Security issues

The Workgroup Server 8550 lets you concentrate valuable or sensitive information on one system that can be physically isolated and more carefully monitored than would be possible if that information were stored on personal computers. Before you set up the server, you may want to consider two measures that you can take to secure the hardware components: physically isolating the system and using a locking cable to secure the system.

Physically isolating the system

It is important to note that even if software security features (such as password protection or locking screen savers) are in use on the server, it is still possible to disconnect peripheral devices from your server. There is no better way to protect hardware components than by physically isolating the server system???locking it either in a well-ventilated cabinet or in a room with controlled access. Depending on your security needs, the nature of the data stored on the server and its external drives may warrant the effort.

Using a locking cable

As an alternative to isolating the system completely in an area of controlled access, you can purchase a locking cable and attach it to your server. The back panel has a built-in port for a locking cable. Follow the instructions supplied with the locking cable to secure it to your server.

F Security

lock ports

8 Chapter 1 / Setting Up Your Server

By itself, a locking cable cannot prevent unauthorized use of the server, but it can prevent the server (and its peripheral devices if they are also secured by locking cables) from being removed.

Installing internal devices

If you purchased additional internal drives or expansion cards for your server, install them now (see Chapter 3 for instructions). If you don???t have internal devices to install, go on to the next section, ???Connecting a Monitor.???

Connecting a monitor

You can connect many types of monitors (often called displays) to your server, including most standard monitors. See Appendix B, ???Technical Information,??? for a complete list.

This section contains instructions for connecting most types of monitor. To connect a monitor from a manufacturer other than Apple, refer also to the instructions that came with the monitor.

Connecting the monitor???s power cord

Monitors have two cords to connect: a power cord and a monitor cable. To connect the monitor power cord:

1Place the monitor where you will be using it.

Keep in mind these considerations:

m Allow a few inches for air circulation around the server and monitor.

m Make sure the top of the screen is slightly below eye level when you???re sitting at the keyboard.

m Position the monitor to minimize glare and reflections on the screen from overhead lights and windows.

m Consult ???Arranging Your Office??? in Appendix A for suggestions about locating your server equipment.

2Connect the monitor???s power cord to the monitor.

On some monitors, the cord is already attached.

3Plug in the monitor???s power cord to the server or grounded electrical outlet.

Some power cords are designed to plug into the back of your server. You

can also plug the power cord into a grounded electrical outlet (an adapter may be needed).

Note: If you have an Apple AudioVision monitor, plug the monitor???s power cord into the back of the server, not into an outlet.

Some monitors have to be connected to a grounded power outlet, not to the server???s power socket. Check the information that came with the monitor.

10 Chapter 1 / Setting Up Your Server

Connecting the monitor cable

After you plug in the monitor???s power cord, connect the monitor cable to the server???s monitor port.

To connect the monitor cable:

1Attach the monitor cable to the monitor.

On some monitors, the cable is already attached.

2Attach the monitor cable to the server???s monitor port.

The monitor port is marked with the icon ???. To connect the cable, firmly push it into the connector and then use the thumbscrews to secure the connection.

If you have an AudioVision monitor, see the information that came with the monitor to use its special features.

IMPORTANT The only way to disconnect power completely is to unplug the power cord. Make sure at least one end of the power cord is within easy reach so that you can unplug the server when you need to.

14 Chapter 1 / Setting Up Your Server

Turning the server on

Before turning the server on, make sure it is in its upright position; the

Workgroup Server 8550 is not designed to run on its side.

To turn on the server for the first time, follow these steps.

1Turn on the monitor.

See the information that came with your monitor for the location of the power switch. On Apple monitors, the power switch has this icon: I.

Note: You only need to turn on the monitor once if its power cord is plugged into the server. From now on, the monitor will turn off automatically when you shut down the server, and it will turn on automatically when you start up the server. (If the monitor???s power cord is not plugged into the server, it must be turned on separately each time you turn on the server.)

2Turn on all external devices.

External devices may include hard disk drives, CD-ROM drives, or tape- backup drives. The server checks only once???at startup???for the presence of external devices, so you need to turn on the devices before you turn on the server.

3Turn on your server by pressing the Power key on the keyboard or pressing the Power button on the front panel of the server.

You???ll find the Power key at the top of the keyboard. You can recognize this key by the triangle outline.

1 Choose Shut Down from the Special menu.

2Respond to the dialog boxes that may appear.

Applications that are running may display dialog boxes that prompt you to save open files or that ask you to enter a message that is to be displayed to users who are logged in to your server.

18 Chapter 1 / Setting Up Your Server

The Workgroup Server 8550 contains built-in hardware and software for connecting the server to two types of networks: LocalTalk and Ethernet. With the appropriate Peripheral Component Interconnect (PCI) card and software, you can also connect your server to additional networks, including other network types, such as Token Ring, Integrated Services Digital Network (ISDN), Fiber Distributed Data Interface (FDDI), and Fast Ethernet (100BASE-T) networks.

You connect the server to a LocalTalk network through the printer port. The built-in Ethernet ports on the Workgroup Server 8550 let you connect the server to an Ethernet network through either the AAUI (Apple Attachment Unit Interface) Ethernet connector or the 10BASE-T Ethernet interface connector. (Although you can connect cables to both of these Ethernet ports at the same time, you can use only one of these built-in Ethernet connections at a time.)

The Workgroup Server 8550 is preconfigured to use the built-in Ethernet connection. If both 10BASE-T and AAUI networks are connected to the built- in Ethernet ports, your server automatically uses the 10BASE-T connection. See Chapter 2, ???Configuring Your Network Connection,??? in the Workgroup Server Administrator???s Guide for instructions on changing the default network connection for your server.

Although your server is preconfigured to access one network segment at a time, with network server software (such as AppleShare 4.2.1) that supports the multihoming capabilities of Open Transport 1.1 (new communications software that is part of the Mac OS included with your server), you can set up your server to access multiple network segments at the same time. See the section ???Building a High-Performance Network??? later in this chapter for more information on multihoming.

19

Connecting to an Ethernet network

The built-in Ethernet capabilities of your Workgroup Server 8550 allow you to connect to any standard Ethernet network using thin coaxial (or ???coax???), 10BASE-T twisted-pair, or thick coaxial cables; fiber-optic media; or other standard Ethernet cables.

You can connect your server directly to an Ethernet network using a 10BASE-T twisted-pair cable. To connect the server to an Ethernet network using coaxial cables, you need one of the following Ethernet media adapters:

mApple Ethernet Thin Coax Transceiver

mApple Ethernet AUI Adapter

See your Apple-authorized dealer for more information on Apple Ethernet media adapters for your Workgroup Server 8550.

WARNING Do not connect cables to the back of the server when the power is on or you may damage your system.

You can connect an adapter and cable for an Ethernet network directly to the server without installing an expansion card. You can find the Ethernet ports on the back of your server by looking for the Ethernet icon:

Although you can connect cables to both of these Ethernet ports at the same time, you can use only one of these built-in Ethernet connections at a time.

The following sections provide basic instructions for connecting your server to an Ethernet network.

20 Chapter 2 / Connecting to the Network

Connecting to twisted-pair Ethernet

Follow this procedure to connect the server to a network that implements Ethernet over twisted-pair cable. The hardware connection requires a twisted- pair patch cord with an RJ-45 telephone-style connector jack. You plug the patch cord into a standard wall plate that is connected to a centralized 10BASE-T hub.

To connect the server to a twisted-pair network:

1Make sure that the server is turned off.

2Plug one end of the twisted-pair patch cord into an RJ-45 wall outlet that supports twisted-pair Ethernet.

3-meter patch cord

3Plug the other end of the twisted-pair patch cord into the 10BASE-T Ethernet port on the server.

The server is preset to use the network software connection for Ethernet. You can use network services as soon as you start up the server.

Connecting to thin coaxial Ethernet

Follow this procedure to connect the server to an Ethernet network that uses thin coaxial cable. The hardware connection requires an Apple (or Apple- compatible) thin coaxial transceiver and a thin coaxial cable.

To connect the server to a thin coaxial network:

1Make sure that the server is turned off.

2Attach one end of a thin coaxial cable to one of the posts on the thin coaxial transceiver.

3Attach the other end of the cable to the last thin coaxial transceiver on the network.

A thin coaxial network must be terminated at the endpoints to function. An Apple transceiver is self-terminating. A non-Apple transceiver may require a terminator; check the documentation that came with the transceiver.

Note: You can connect the server anywhere along a network; however, to do so requires that you temporarily disconnect the network, which could disrupt existing network services.

4Plug the connector on the transceiver into the AAUI Ethernet port on the server.

Connecting to other types of Ethernet

The Apple Ethernet AUI Adapter is a universal adapter that lets you connect the server to less-common types of industry-standard Ethernet media, such as thick coaxial or fiber-optic cable. If you are using the Apple Ethernet AUI Adapter, you also need an Ethernet transceiver for your specific media type, and the transceiver must have a standard AUI port on it.

To connect the server to an Ethernet transceiver for other types of Ethernet media:

1Make sure that the server is turned off.

2Connect the Ethernet transceiver to the network following the instructions in the documentation that came with the transceiver.

3Plug the transceiver cable from the Ethernet transceiver into the standard AUI port on the Apple Ethernet AUI Adapter.

Connecting to a LocalTalk network

To connect your server to a LocalTalk network, you will need LocalTalk cables and a LocalTalk adapter. The Apple LocalTalk Locking Connector Kit DIN-8, available from your Apple-authorized dealer, contains the components you need to connect the server to an existing LocalTalk network by means of the printer port.

24 Chapter 2 / Connecting to the Network

Now that you have made the server???s physical connection to LocalTalk, you can start up the server.

IMPORTANT After connecting to a LocalTalk network (if you have not also connected to Ethernet), each time you start up the server you???ll see a dialog box that indicates an error condition. This dialog box informs you that the system has made a temporary switch from EtherTalk (its preset network software connection) to LocalTalk. You will see this message until you change the default setting in the AppleTalk control panel. Turn to Chapter 2, ???Configuring Your Network Connection??? in the Workgroup Server Administrator???s Guide to learn how to switch the setting in the AppleTalk control panel.

Building a high-performance network

Your Workgroup Server 8550 is designed to support a multisegment, high- performance network. Connection devices such as repeaters, bridges, routers, and gateways extend network segments and provide efficient links between a variety of network segments. For information about extending and connecting AppleTalk networks, see Planning and Managing AppleTalk Networks (an Apple book published by Addison-Wesley that is available at computer bookstores).

In addition to its built-in Local Talk and Ethernet ports, your server has three expansions slots where you can install PCI cards for connecting additional network segments, including different network types such as Token Ring, Integrated Services Digital Network (ISDN), Fiber Distributed Data Interface (FDDI), and Fast Ethernet (100BASE-T) networks. The multihoming capabilities of Open Transport 1.1, the new networking and communications software that is part of the Mac OS, make it possible for your server to access multiple network segments at the same time.

Creating a high-performance Ethernet segment

You can increase performance in Ethernet networks by creating subnetworks of devices connected by 10BASE-T Ethernet hubs (repeaters that regenerate signals from one device to another). The Apple Ethernet 10T/5 Workgroup Hub provides a modular, plug-and-play approach to creating and expanding high-performance Ethernet networks. This hub gives you a simple, cost- effective means of connecting together a wide variety of Macintosh and other personal computers, Workgroup Servers, and Ethernet-capable printers.

One of the easiest and most cost-effective ways to increase bandwidth is to connect network devices with switched Ethernet hubs. A switched hub connects devices on a 10BASE-T network, but it switches packets between ports, instead of passing them across a shared backbone, allowing each device that is connected to the switched hub to use the entire capacity of the link. In a 10BASE-T network, you may want to dedicate switched hubs to devices that require extra bandwidth, such as file servers. You can create a high-speed (100BASE-T) Ethernet segment by installing a 100MB Ethernet PCI expansion card in your server (see Chapter 3 for card installation instructions) and using high-performance switched hubs to connect the network devices.

Contact your Apple-authorized dealer for help selecting PCI expansion cards and hubs to optimize performance on your Ethernet networks.

26 Chapter 2 / Connecting to the Network

Using multiple network segments

By installing additional PCI network cards (and associated software), you can connect your server to a variety of networks. To use more than one network segment at the same time, you will also need network server software that supports multihoming on PCI-based systems (such as AppleShare 4.2.1). The following illustration is an example of a server that has multihoming enabled on the built-in Ethernet and LocalTalk connections, as well as on two additional network connections provided by PCI network cards.

Ethernet connection

LocalTalk connection

Other network connections

Multihoming allows

this server to communicate with up to four networks.

Setting up multihoming

Follow these steps to set up multihoming capabilities on your server:

1Install PCI network cards (and associated software) for additional network segments that you want to connect to your server.

Follow the instructions in Chapter 3 of this setup guide.

Note: This step is optional, as you can take advantage of multihoming capabilities even when network segments are connected only to the built-in LocalTalk and Ethernet ports on your server.

2Con???gure the Open Transport options for your server.

Follow the instructions for configuring your AppleTalk network connection in Chapter 2, ???Configuring Your Network Connection,??? of the Workgroup Server Administrator???s Guide.

IMPORTANT Each port must be assigned to a different zone.

3Con???gure your network server software to enable multihoming on your server.

See the documentation that accompanied your network server software. (For AppleShare version 4.2.1, see the Addendum to AppleShare Administrator???s Guide.)

Use a router to connect each network segment

Although users on different multihomed network segments can share and exchange ???les by using the server as a common storage area, each multihomed network segment is not visible to the other segments without use of a router. For example, suppose you have four multihomed network segments connected to your server (A, B, C, and D). Computers and other network devices such as LaserWriter printers on segment A are not visible to segments B, C, or D unless there???s a router between A and the other three segments.

28 Chapter 2 / Connecting to the Network

Have users select the server in their own zone

If network segments connected to your server are connected to each other through routers, users will see the server in all the connected zones (in the Chooser). For best performance, make sure that users select in the Chooser the server that resides in the same zone as their own computer.

For instance, in the following illustration, users will be able to see the Archives server in Zones 1, 2, 3 and 4. Users in Zone 1 should log on to the Archives server in Zone 1.

Zone 1

Users in Zone 1 should select the Archives server

visible in the Chooser in Zone 1.

You can expand the capabilities of your server by installing items internally and by connecting external devices. The following figure shows you the location of the Workgroup Server 8550???s internal components. An external view of the server, depicting the ports to which you connect other devices, is shown in the section ???Your Server at a Glance??? in Chapter 1.

IMPORTANT Make sure each device you add is compatible with your server and does not exceed the maximum power allowance for that device. If it is a SCSI, ADB, or internal device, make sure to turn off your server before connecting the device. For further information, consult your Apple-authorized dealer, the manufacturer of the component you want to add, or Appendix B, ???Technical Information.???

Opening the server safely

WARNING The components in your server, as well as the internal devices that you may install in your server, are very susceptible to damage from electrostatic discharge. When opening your server and while installing internal devices in the server, it is very important to take precautions to protect the server???s components from static electricity damage.

You can take the following preventative measures to avoid electrostatic discharge while you are installing internal devices in your server:

mWear a grounded wriststrap (like the one shown below) while installing internal devices in the server.

mCarefully follow all instructions for discharging static electricity included in the procedures in this chapter.

Follow these steps to open the server:

1Make sure that the server is shut down and that any cables (including the power cord) are disconnected from the server.

2Press the Power button to discharge static electricity.

32 Chapter 3 / Expanding Your Server and Connecting Other Equipment

3Loosen the four large screws at the corners of the back panel.

Do not remove the screws or the back panel.

4Remove the cover from the server.

Slide the cover away from the back panel an inch or two. Then raise the cover straight up and off the server.

Installing an expansion card

You can install printed circuit boards (called cards) for networking and communications, SCSI acceleration, video and graphics applications, or other purposes. The cards fit into connectors, called expansion slots, inside the server.

Your Workgroup Server 8550 has three expansion slots, each designed to accept a Peripheral Component Interconnect (PCI) card. Install only expansion cards that come with Mac OS drivers and are compliant with the PCI 2.0 standard. NuBus cards cannot be used in your server???s expansion slots. There is also an expansion slot that contains the server???s processor card. (The processor card can be upgraded by replacing it with a more powerful processor card.)

WARNING To avoid damaging your server and expansion card, do not attempt to install any expansion card without first checking the documentation for that card. If the documentation specifies that an Apple-certified technician must install the card (usually because the installation requires special training or tools), consult the service and support information that came with your server for instructions on how to contact an Apple-authorized service provider or Apple for assistance. If you attempt to install the card yourself, any damage you may cause to the server or card will not be covered by the limited warranty on your server. If the card is not an Apple-labeled product, check with an Apple-authorized dealer or service provider to see if you can install it yourself.

Power requirements

The combined power consumption of expansion cards must not exceed the limits specified for your Workgroup Server 8550. If you have more than one expansion card installed, check the information that came with your cards to make sure that their power consumption is within the limits specified in Appendix B, ???Technical Information.???

34 Chapter 3 / Expanding Your Server and Connecting Other Equipment

Installing a PCI expansion card

IMPORTANT Some cards may need to be installed by an Apple-authorized service provider. Check the information that came with the card.

Follow these steps to install an expansion card.

1Carefully follow the instructions provided earlier in this chapter for opening the server safely.

Remember to wear a grounded wriststrap while installing an expansion card.

2Touch the metal part of the power supply case inside the server to discharge static electricity.

Always do this before you touch any parts or install components inside the server.

6 Align the connector end of the card with the expansion slot.

If your expansion card is full-length, be sure that it engages the card guide in the server???s interior.

7Press the card ???rmly until the connector is seated.

m Slide the card between the two levers that held the access port cover you removed earlier. You may need to press the levers apart slightly to guide the card between them.

m Don???t force the card. If you meet a lot of resistance, pull the card out and try again.

m To see if the card is properly connected, pull it gently. If it resists and stays in place, it???s connected. (Make sure you don???t pull the card so much that you accidentally disconnect it.)

If you have other cards to install, put them in now by repeating steps 4 through 7.

8Replace the retainer.

This guide on the retainer engages the processor card in the server.

When the card is properly seated, the levers snap into place and secure the card.

38 Chapter 3 / Expanding Your Server and Connecting Other Equipment

9Replace the cover on the server.

Lower the cover all the way down onto the case. Push the cover toward the back until it touches the back panel.

10Tighten the screws on the back panel.

You are now finished installing the card. If a software driver was included with your expansion card (on a floppy disk), after you finish setting up your server and turn it on, you will need to install the driver.

Return to Chapter 1 to complete the steps for setting up and turning on your server, and then, if you need to install driver software, refer to the documentation that accompanied the expansion card and to ???Installing Device Drivers??? in Chapter 1 of the Workgroup Server Administrator??? Guide.

WARNING Never turn on your server unless all of its internal and external parts are in place. Operating the server when it is open or missing parts can be dangerous, and can damage your server.

Upgrading the processor

Your server???s processor can be upgraded with the installation of a processor upgrade card.

To upgrade the processor, remove the old processor card following the instructions earlier in this chapter for opening the server safely. Then, the new processor card can be installed following the procedure in this chapter for installing expansion cards. (Note that an access port cover does not need to be removed as described in step 4 of ???Installing a PCI Expansion Card??? earlier in this chapter.)

IMPORTANT The processor card can be damaged by static electricity. To avoid damaging the card, hold it only by the edges???do not touch the connectors or the components on the card.

Refer to the documentation that came with the processor upgrade card for important installation instructions specific to the card.

40 Chapter 3 / Expanding Your Server and Connecting Other Equipment

Expanding memory

Additional memory can be installed in your server. Memory for your server is provided in packages called Dual Inline Memory Modules (DIMMs). Appendix B, ???Technical Information,??? describes how much additional memory can be installed in the server.

Adding dynamic random-access memory (DRAM) DIMMs increases your server???s memory. The DRAM DIMMs must be the correct type for your server, and can be installed one at a time. For the best performance, however, the DRAM DIMMs should be installed in pairs of the same size into paired slots in your server.

You can also improve your server???s performance by upgrading the Level 2 (L2) cache with a higher-capacity cache DIMM. (The L2 cache stores the most frequently used portions of memory in high-speed RAM.)

The memory used to display images on the screen (called video RAM, or VRAM) can also be expanded by installing DIMMs. VRAM DIMMs must be installed in pairs.

It is very important that the DIMMs be correctly installed in your Workgroup Server 8550. Incorrect installation can result in errors, unpredictable results, and damage to your equipment and data.

WARNING To avoid damage to your server, Apple recommends that only an Apple-certified technician install additional DIMMs. Consult the service and support information that came with your server for instructions on how to contact an Apple-authorized service provider or Apple for service. If you attempt to install additional DIMMs yourself, any damage you may cause to your equipment will not be covered by the limited warranty on your server. See an Apple-authorized dealer or service provider for additional information about this or any other warranty question.

Expanding memory 41

Connecting hard disks and other SCSI devices

Your Workgroup Server 8550 has two buses for connecting devices that use the Small Computer System Interface (SCSI, pronounced ???skuh-zee???). The SCSI connections permit high-speed communication between the server and the devices. SCSI devices commonly attached to the Workgroup Server 8550 include hard disks, CD-ROM drives, scanners, printers, and tape-backup drives.

IMPORTANT Before connecting a device to your server, be sure that the server (and any other device already connected to it) is turned off. Read the instructions in this section and the instructions that came with your hard disk or other SCSI device before connecting it to your server.

Bus A is the internal Fast SCSI-2 bus (10 MB per second) that connects your server???s CPU to the built-in disk drive in the bottom bay of the internal disk drive bracket. Additional devices cannot be connected to the internal SCSI bus (unless the cabling for this bus is modified by an Apple-authorized service provider).

Bus B is an internal/external SCSI-1 bus (5 MB per second) to which a total of seven devices can be connected. The CD-ROM drive that is built into your server is connected to the internal/external SCSI bus. The optional internal hard disk (which can be installed in the top bay of the internal disk drive bracket) and the optional built-in DAT drive (or any other drive in your server???s auxiliary bay) are also connected to this internal/external SCSI bus when installed. Your server has a port for connecting additional external SCSI devices to the internal/external SCSI bus. The SCSI icon appears above the port on the server???s back panel.

SCSI icon

SCSI port

You can connect SCSI devices to the SCSI port in a chain. The first device in the chain plugs into the SCSI port; the second device plugs into the first device, and so on. If the only device connected to your server???s

internal/external SCSI bus is its built-in CD-ROM drive, you can attach up to six external SCSI devices. However, if you have a built-in DAT drive and a second internal hard disk connected to this SCSI bus, you can attach only four external SCSI devices to the port.

42 Chapter 3 / Expanding Your Server and Connecting Other Equipment

Devices on the same SCSI bus must have unique ID numbers (however, devices on different SCSI buses may use the same SCSI ID number).

Setting up a SCSI device to use with your server involves:

msetting the device???s SCSI ID number

mphysically connecting the device to your server (including appropriate termination)

minstalling any necessary device drivers (and restarting your system)

Setting the SCSI ID number

If you have a SCSI device not sold by Apple, see the instructions that came with that device for information on setting its SCSI ID number.

WARNING Each SCSI device connected to your server must have its own, unique SCSI ID number. Using two or more devices with the same ID number (on the same SCSI bus) can cause your equipment to malfunction.

If you have an Apple SCSI device, set the SCSI ID number as follows:

1Make sure your server is shut down and the SCSI device is turned off.

2Choose a number between 0 and 6 that doesn???t duplicate the ID of any other SCSI device connected to your server on the same SCSI bus.

The following table shows the server???s default SCSI ID numbers as well as the SCSI ID numbers available for you to use on the internal/external bus.

Connecting hard disks and other SCSI devices 43

On the internal/external bus, you can use SCSI ID numbers 0, 4, 5, 6. The secondary hard disk (in the top bay of the internal disk drive bracket), the optional built-in DAT drive (or any other drive in your server???s auxiliary bay), and the built-in CD-ROM drive reserve SCSI IDs 1, 2, and 3, respectively, on the internal/external bus. If you do not have a secondary hard disk in the internal disk drive bracket, you can also use SCSI ID 1 for this bus; if you do not have a DAT or other drive in the auxiliary bay, you can use SCSI ID 2 on this bus.

3 Locate the ID number switch on the back of your SCSI device.

SCSI ID switch

4Push the ID switch repeatedly until the number you want appears.

On some SCSI devices, the ID number switch is inside a small hole. Insert a straightened paper clip to push the switch.

Follow the instructions in the next section to install an additional hard disk in the internal disk drive bracket. To replace or install a drive in the server???s auxiliary bay, see ???Installing a Drive in the Auxiliary Bay.???

4 If you are replacing a drive, slide the drive out of the bay.

5Con???rm that the new drive has its own, unique ID number between 0 and 6.

SCSI ID 2 is recommended for a device in the auxiliary bay. See the section ???Setting the SCSI ID Number??? earlier in this chapter for details.

6Check the termination status of the new drive.

You do not need to terminate a drive installed in the auxiliary bay. The internal end of internal/external SCSI bus should be terminated already, either by the termination block at the end of the SCSI ribbon cable or by a terminated disk drive in the upper bay of the internal disk drive bracket.

Only one internal terminator is allowed on the internal/external SCSI bus. If the drive that you are installing in the auxiliary bay has a built-in terminator, and there is no disk drive in the upper bay of the internal disk drive bracket, you can remove the termination block at the end of the SCSI ribbon cable and allow the device you are installing to terminate the bus. However, if there is a disk drive in the upper bay of the internal disk drive bracket, this device is at the end of the internal SCSI chain and must terminate the bus. In this case, you should have an Apple-authorized service provider remove any built-in terminator from the drive that you want to install in the auxiliary bay.

56 Chapter 3 / Expanding Your Server and Connecting Other Equipment

7If necessary, attach the new drive to its bracket.

Follow the instructions that came with the new drive and bracket.

WARNING Never turn on your server unless all of its internal and external parts are in place. Operating the server when it is open or missing parts can be dangerous, and can damage your server.

Connecting hard disks and other SCSI devices 59

Connecting an external SCSI device

To connect a SCSI device to the port on your server???s back panel:

1 Make sure that the server and SCSI device are turned off.

WARNING Do not connect or disconnect any device while the device or your server is turned on. Doing so could damage the device, your server, or both.

2Check that the device has its own, unique ID number between 0 and 6.

See the section ???Setting the SCSI ID Number??? earlier in this chapter for details.

3Use a SCSI cable to connect the device either to the server???s SCSI port or to the last SCSI device already in the chain.

If the device is the first or only one you???re connecting, use a SCSI system cable to connect it to the server???s SCSI port.

If the device is not the first one, use a SCSI peripheral interface cable to connect it to the last device in the chain.

IMPORTANT To get the best results with SCSI devices, be sure to use high- quality SCSI cables and check that the total length of the cables in a SCSI chain does not exceed 6 meters (20 feet). Use SCSI cables manufactured by Apple Computer or those of similar quality.

60 Chapter 3 / Expanding Your Server and Connecting Other Equipment

4Make sure that only the last device in the SCSI chain has a terminator and that no other external SCSI device has a terminator.

To ensure accurate transmission of information, a terminator must be at each end of a SCSI chain.

Some external SCSI devices from manufacturers other than Apple have a built-in terminator. (Check the information that came with the device.) If the device at the end of the SCSI chain does not have a built-in terminator, you need to attach an external terminator.

External SCSI terminator

If your SCSI device has a built-in terminator, you may choose to use it as either the only device or the last device in the chain, or you may have your Apple-authorized service provider remove any extra built-in terminators. You can attach or remove external terminators yourself.

Note: If only one external device has a built-in terminator, rearrange the SCSI chain so that device is at the end.

IMPORTANT Always turn on any external SCSI devices connected to your server before turning on the server itself. Otherwise, your server cannot recognize the SCSI devices.

Before using the newly installed SCSI device, you may need to install associated software; see the following section, ???Installing a Device Driver.??? If you installed a hard disk, see also the subsequent section, ???Do You Need to Initialize a Hard Disk????

Connecting hard disks and other SCSI devices 61

Installing a device driver

A SCSI device driver is software that lets the server communicate with a particular SCSI device.

Note: If you have set up your server and connected additional devices, but not yet turned the server on, return to the section ???Plugging In the Server??? in Chapter 1 before installing a device driver.

To install a driver:

mStart up your server, if necessary, and drag the driver icon to the System Folder icon on your startup disk.

Any drivers needed for a SCSI device are usually on a floppy disk that comes with the device. (If no drivers come with the device, then it doesn???t need any.) You may have to restart your server to activate the driver.

Do you need to initialize a hard disk?

You need to initialize a hard disk only in the following cases:

mThe disk is new and uninitialized. Your internal hard disk and most external hard disks are initialized at the factory and do not have to be initialized again. If you are adding a new non-Apple hard disk to your server, check your owner???s manual to see if it needs to be initialized.

mYou???ve experienced repeated errors using this disk. If problems persist after you reinitialize the disk, the disk is in need of servicing.

You use the Apple Drive Setup program to initialize and name a hard disk. Apple Drive Setup is provided as part of your system software and can be found in the Utilities folder on the server???s hard disk as well as on the Workgroup Server Software CD-ROM disc. See Chapter 4, ???Managing Hard Disks,??? in the Workgroup Server Administrator???s Guide and the instructions for preparing a disk for use in the ???Disks??? topic in Macintosh Guide, available in the Guide (h) menu.

If you are using the Apple RAID Software that accompanied your Workgroup Server, you may want to use the Apple RAID Setup program to reinitialize your hard disk(s) to optimize your server???s performance. See the Apple RAID Administrator???s Guide for instructions.

With appropriate software, you can use an Apple PlainTalk Microphone (or a compatible line-level microphone) to give spoken commands to your server and to record your voice or other sounds.

Apple PlainTalk Microphone

Do not use the round omnidirectional microphone supplied with some other Macintosh models.

Follow these steps to connect and position the microphone:

1Shut down the server.

2Plug the microphone???s connector into the sound input port (X) on the back of the server.

3Place the microphone at the top center of the monitor, so that the microphone???s Apple (K) icon is facing you.

If you can???t place the microphone on top of the monitor, position the microphone according to these guidelines:

mThe microphone should be between 1 and 3 feet away from you.

mThe microphone should be directly in front of you to minimize the effect of background noises.

68 Chapter 3 / Expanding Your Server and Connecting Other Equipment

4Turn on the server.

You???re now ready to begin using your microphone.

You may want to install software that enables you to give spoken commands to the server, get computer-voice feedback to your spoken commands, and have the server read text to you. For information about installing software on your server, see Chapter 3, ???Using Application Software,??? in the Workgroup Server Administrator???s Guide. To set the sound options for your microphone, see ???Choosing Sound Devices and Alert Sounds??? in Chapter 1 of the

Workgroup Server Administrator???s Guide. For further instructions on how to use speech software, see the ???Speech??? topic of Macintosh Guide, available in the Guide (h) menu.

Connecting external stereo speakers

You can take advantage of your server???s stereo sound output by attaching externally powered (amplified) speakers.

1Assemble the speakers and the cable you need.

You need a cable with stereo miniplugs at each end to connect one or both speakers to the server. (Some speakers require a dual-plug adapter. Others, like those shown in the next illustration, accept a single stereo miniplug and are joined by standard speaker wires.)

2Turn off the server.

3Plug a stereo miniplug into the sound output port (-) on the server.

4Plug a stereo miniplug into the Audio In port on one of the speakers.

If the speakers take a dual-plug cable, connect both plugs.

5Connect the speakers together with speaker wires, if necessary.

Your finished connections should look something like this:

-Sound output port

6Turn on the server.

Now you hear the server???s sound through the external speakers. (You may also need to set options in the Sound & Displays control panel in order to hear sound through your speakers. To set sound options, see ???Choosing Sound Devices and Alert Sounds??? in Chapter 1 of the Workgroup Server Administrator???s Guide. Refer to the ???Sound??? topic of Macintosh Guide, available in the Guide [h] menu, for more information.)

Note: Use the Sound & Displays control panel to control volume and to set other options for playing sound through the external speakers. If you are playing an audio CD, you may also need to adjust the volume control in the program you???re using to play CDs.

80 Appendix A / Safety, Maintenance, and Health Information

Health-related information about computer use

Muscle soreness, eye fatigue, and other discomforts and injuries sometimes associated with using computers can occur from performing any number of activities. In fact, misuse of the same muscles during multiple activities can create a problem that might not otherwise exist. For example, if you engage in nonwork activities that involve repetitive stress on the wrist???such as bicycling???and also use your computer keyboard improperly, you may increase your likelihood of developing wrist problems. Some individuals are at greater risk of developing these problems because of their health, physiology, lifestyle, and general exposure to stress. Work organization and conditions, such as workstation setup and lighting, also play a part in your overall health and comfort. Preventing health problems is a multifaceted task that requires careful attention to the way you use your body every hour of every day.

The most common health effects associated with using a computer are musculoskeletal discomfort and eye fatigue. We???ll discuss each area of concern below. For information about electric and magnetic emissions, look in the reference material that came with your server.

Musculoskeletal discomfort

As with any activity that involves sitting for long periods of time, using a computer can make your muscles sore and stiff. To minimize these effects, set up your work environment carefully, using the guidelines that follow, and take frequent breaks to rest tired muscles. To make working with your computer more comfortable, allow enough space in your work area so that you can change position frequently and maintain a relaxed posture.

Another type of musculoskeletal concern is repetitive stress injuries (RSIs), also known as cumulative trauma disorders (CTDs). These problems can occur when a certain muscle or tendon is repeatedly overused and forced into an unnatural position. The exact causes of RSIs are not totally understood, but in addition to awkward posture, such factors as the amount of repetition, the force used in the activity, the individual???s physiology, workplace stress level, and lifestyle may affect the likelihood of experiencing an RSI.

RSIs did not suddenly arise when computers were invented; tennis elbow and writer???s cramp, for example, are two RSIs that have been with us for a long time. Although less common than other RSIs, one serious RSI discussed more often today is a wrist problem called carpal tunnel syndrome, which may be aggravated by improper use of computer keyboards. This nerve disorder results from excessive pressure on the median nerve as it passes through the wrist to the hand.

This section offers advice on setting up your work area to enhance your comfort while you use your computer. Since the effects of repetitive movements associated with using a computer can be compounded by those of other work and leisure activities to produce or aggravate physical problems, proper use of your computer system must be considered as just one element of a healthy lifestyle.

No one, of course, can guarantee that you won???t have problems even when you follow the most expert advice on using computer equipment. You should always check with a qualified health specialist if muscle, joint, or eye problems occur.

Eye fatigue

Eye fatigue can occur whenever the eyes are focused on a nearby object for a long time. This problem occurs because the eye muscles must work harder to view an object that???s closer than about 20 feet (6 meters). Improper lighting can hasten the development of eye fatigue. Although eye fatigue is annoying, there???s no evidence that it leads to permanent damage.

Whenever you???re engaged in an activity that involves close-up work???such as reading a magazine, doing craft work, or using a computer???be sure to have sufficient glare-free lighting and give your eyes frequent rest breaks by looking up and focusing on distant objects. Remember to have your eyes examined regularly.

To prevent discomfort and eye fatigue:

mArrange your workspace so that the furniture is properly adjusted for you and doesn???t contribute to an awkward working posture.

mTake frequent short breaks to give your muscles and eyes a chance to rest.

82 Appendix A / Safety, Maintenance, and Health Information

Arranging your office

Here are some guidelines for adjusting the furniture in your office to accommodate your physical size and shape.

mAn adjustable chair that provides firm, comfortable support is best. Adjust the height of the chair so that your thighs are horizontal and your feet flat on the floor.

The back of the chair should support your lower back (lumbar region). Follow the manufacturer???s instructions for adjusting the backrest to fit your body properly.

mWhen you use the computer keyboard, your shoulders should be relaxed. Your upper arm and forearm should form an approximate right angle, with your wrist and hand in roughly a straight line.

You may have to raise your chair so that your forearms and hands are at the proper angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you can use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you may lower the desktop to eliminate the need for a footrest. Another option is to use a desk with a keyboard tray that???s lower than the regular work surface.

mPosition the mouse at the same height as your keyboard. Allow adequate space to use the mouse comfortably.

45???70 cm (18???28 in.)

Shoulders relaxed

Forearms and hands in a straight line

Forearms level or tilted up slightly

Lower back supported

Thighs horizontal

Top of the screen at or slightly below eye level (You may need to adjust the height of your monitor by placing something under it or by raising your work surface.)

Screen positioned to avoid reflected glare

Clearance under work surface

Feet flat on the floor

mArrange the monitor so that the top of the screen is slightly below your eye level when you???re sitting at the keyboard. The best distance from your eyes to the screen is up to you, although most people seem to prefer 18 to 28 inches (45 to 70 cm).

mPosition the monitor to minimize glare and reflections on the screen from overhead lights and windows. You may want to use a tiltable monitor stand. The stand lets you set the monitor at the best angle for viewing, helping to reduce or eliminate glare from lighting sources you can???t move.

Avoiding fatigue

mChange your seated position, stand up, or stretch whenever you start to feel tired. Frequent short breaks are helpful in reducing fatigue.

mUse a light touch when typing or using a mouse and keep your hands and fingers relaxed.

mSome computer users may develop discomfort in their hands, wrists, or arms after intensive work without breaks. If you begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a qualified health specialist.

mAllow adequate workspace so that you can use your keyboard and mouse comfortably. Place papers or other items so that you can view them easily while using your computer. A document stand may make reading papers more comfortable.

mEye muscles must work harder to focus on nearby objects. Occasionally focus your eyes on a distant object, and blink often while you work.

mClean your screen regularly. Keeping the screen clean helps reduce unwanted reflections.

84 Appendix A / Safety, Maintenance, and Health Information

What about electromagnetic emissions?

There has been recent public discussion of the possible health effects of prolonged exposure to extremely low frequency (ELF) and very low frequency (VLF) electromagnetic fields. Such fields are associated with electromagnetic sources such as television sets, electrical wiring, and some household appliances???as well as computer monitors.

Apple has reviewed scientific reports and sought the counsel of government regulatory agencies and respected health organizations. Based on the prevailing evidence and opinions, Apple believes that the electric and magnetic fields produced by computer monitors do not pose a health risk.

In response to those customers who wish to reduce their exposure to electromagnetic fields, Apple has lowered the emission levels of our products. We are also actively encouraging further scientific research so we can continue to promote the health and safety of our customers and employees.

mone 512K DIMM of static RAM (SRAM) used as an L2 cache, upgradable to 4 MB

DRAM, VRAM, and cache configurations

You can have memory???dynamic random-access memory (DRAM) or video random-access memory (VRAM)???added to your server in packages called Dual Inline Memory Modules, or DIMMs. You can also upgrade your server???s L2 cache by installing a DIMM.

Specifications 89

WARNING To avoid damage to your server, Apple Computer recommends that only an Apple-certified technician install additional DIMMs. Consult the service and support information that came with your server for instructions on how to contact an Apple-authorized service provider or Apple for service. If you attempt to install additional DIMMs yourself, any damage you may cause to your equipment will not be covered by the limited warranty on your server. See an Apple-authorized dealer or service provider for additional information about this or any other warranty question.

DRAM configurations

Your server can use any DRAM configuration with DIMMs of these sizes: 8, 16, 32, or 64 MB. The exact configuration depends on the density of the DRAM chips that are mounted on the DIMMs.

You can increase your server???s DRAM to up to 512 MB. The main logic board has eight slots where DIMMs can be installed. To increase DRAM to

the maximum of 512 MB, have an Apple-authorized dealer or service provider fill all eight slots with 64 MB DIMMs. You can also fill slots with 8, 16, or 32 MB DIMMs.

Note: 128 MB DIMMs can fit in the server???s memory slots to increase DRAM to as much as 1 gigabyte (GB). These DIMMs have not been tested for use with Workgroup Server 8550 systems, however.

IMPORTANT The DIMMs should be 64-bit-wide, 168-pin fast-paged mode, with 70-nanosecond (ns) RAM access time or faster. The Single Inline Memory Modules (SIMMs) from older Macintosh computers are not compatible with your server and should not be used.

90 Appendix B / Technical Information

VRAM configurations

VRAM, like standard DRAM, is also provided in DIMMs. Your server comes with 2 MB of VRAM installed in two 1 MB DIMMs. (These DIMMs are installed in bank 1.) Your server???s VRAM can be expanded to a maximum of 4 MB by adding two 1 MB DIMMs to bank 2. Both DIMMs must be added at the same time.

IMPORTANT The VRAM DIMMs must be 32-bit-wide, 112-pin fast-paged mode with 70-ns RAM access time or faster. Do not use the 256K or 512K VRAM SIMMs used in older Macintosh computers.

Cache configurations

Your server has a 512K L2 cache. You can upgrade the L2 cache to a maximum of 4 MB by replacing the existing 512K cache DIMM with a higher-capacity cache DIMM.

Adding DRAM

If you decide to have additional DRAM installed in your server, the DIMMs can be installed one at a time in any order in any of the memory slots.

However, if you wish to take advantage of your server???s memory interleaving capability, which provides maximum performance, you must have the DIMMs installed in pairs and in paired slots. (A1 and B1 are the first pair of slots, A2 and B2 are the second, and so on.) Memory interleaving allows the server to read or write to its memory at the same time that other memory reads or writes are occurring, thus providing faster performance.

Specifications 91

*When installing DRAM, for best performance, fill slots A1 and B1, then A2 and B2, then A3 and B3, and so forth.

Graphics modes

The table on the following page shows the image sizes for monitors that can be connected to the monitor port, along with the number of colors or grays supported with 2 MB of VRAM and with the optional expansion to 4 MB of VRAM.

There are also many special PCI monitor cards available from other manufacturers that can support other monitors and special video requirements. See your Apple-authorized dealer for information.

Note: On some monitors from manufacturers other than Apple, the connector pinout designates one pin for both green video and timing synchronization. These ???sync on green??? monitors are not compatible with Workgroup Server 8550 systems. If you???re not sure what type of monitor you have, check with your dealer.

Mouse

m Supports all models of the ADB mouse.

Interfaces

mOne Apple Desktop Bus (ADB) port supporting up to three ADB input devices (such as a trackball, keyboard, or mouse) daisy-chained through a low-speed, synchronous serial bus.

mMonitor port supporting color and grayscale monitors of various sizes and resolutions. (See ???Graphics Modes??? earlier in this appendix.)

mThree internal expansion slots supporting Peripheral Component Interconnect (PCI) expansion cards. Install only expansion cards that come with Mac OS drivers and that are compliant with the PCI 2.0 standard. NuBus cards cannot be used in these expansion slots.

94 Appendix B / Technical Information

mTwo RS-232/RS-422 serial GeoPort-compatible serial ports, 230.4 Kbits per second maximum (up to 2.048 Mbits per second if clocked externally).

mOne built-in Ethernet 10BASE-T port for direct connection to 10BASE-T networks. (If both AAUI and 10BASE-T connectors are plugged in, the server uses the 10BASE-T connector by default.)

mOne built-in Apple Ethernet AAUI port for connecting to high-speed Ethernet networks. Requires the appropriate AAUI transceiver adapter (10BASE-T, thin coaxial, or thick coaxial).

mOne 3.5 mm sound output port for headphones or line-level devices.

mOne 3.5 mm sound input port for stereo sound input. The sound input port supports the Apple PlainTalk Microphone that comes with some Macintosh computers. The sound input port also supports a standard stereo (miniplug-to-RCA) cable adapter for connecting stereo equipment to your server. It does not support the omnidirectional microphone

(the round microphone shipped with some earlier models of Macintosh) or the attenuated RCA adapter provided with some models of Macintosh.

mOne internal/external SCSI interface that supports up to six external SCSI devices, or one internal device plus five external SCSI devices (the built-in CD-ROM drive is also connected to this interface). If you have a built-in DAT drive and a second internal hard disk, you can attach up to four additional external SCSI devices to this interface. This interface operates at 5 MB per second.

IMPORTANT Some older SCSI devices may require updated drivers. (A ???driver??? is special software that is installed in your System Folder.) Contact the device manufacturer for information on obtaining driver software.

mOne internal Fast SCSI-2 interface that supports the built-in hard disk located in the lower bay of the internal disk drive. This interface operates at 10 MB per second.

Specifications 95

Audio system

mCustom sound circuitry, including stereo generator (digital-to-analog converter, or DAC)???capable of driving stereo miniplug headphones or audio equipment???and stereo sampling hardware (analog-to-digital converter, or ADC) for recording stereo sound.

m16-bit stereo input and output.

mSample rates of 44.1 and 22.05 kilohertz (kHz).

Typical specifications

mMaximum current available for all ADB devices: 500 mA.

Note: The ADB port can support up to three daisy-chained ADB devices.

98 Appendix B / Technical Information

Audio and telecommunications devices

The following table shows power allowances for external devices connected to input ports.

Expansion cards and devices

If you add a PCI expansion card, a 5.25-inch storage device, or a 3.5-inch storage device to your server, make sure the component???s power requirements don???t exceed the maximum power allowances allocated to it by the server.

The maximum power allowances for expansion cards in your server can accommodate three 15-watt or two 25-watt cards. Detailed guidelines are presented in the following table.

*15-watt expansion cards should not consume more than 15 watts of power total. **25-watt cards should not consume more than 25 watts of power total.

***Peak power is for startup only and must not occur in normal operation.

Specifications 99

Assigning SCSI ID numbers

The two SCSI buses can connect up to eight SCSI devices.

Bus A, the internal Fast SCSI-2 bus, is designed to connect one internal hard disk drive (the built-in startup drive) to the server (CPU).

Bus B, the internal/external SCSI-1 bus, is designed to connect an optional secondary internal hard disk (in the upper bay of the internal disk drive bracket), an optional built-in DAT drive (or other internal drive in the server???s auxiliary bay), the built-in CD-ROM drive, and up to four additional external SCSI devices to the server (CPU).

The drives that were installed in your server at the factory, as well as the server itself, have already reserved certain SCSI ID numbers. Other ID numbers are available for assignment to SCSI devices that are added after you buy your server as described in the following table.

100 Appendix B / Technical Information
