Introduction

1 - Introduction

The Lantronix Micro Print Server (MPS) is a multiprotocol print server that provides shared network access to printers for a variety of network protocols and operating systems. The MPS supports the AppleTalk (EtherTalk), Microsoft LAN Manager, Local Area Transport (LAT), IPX (NetWare), and TCP/IP protocols. The MPS can queue multiple pending jobs and service those jobs in the order that they are received from the hosts. The Centronics parallel port on the back of the MPS is compatible with the Hewlett-Packard Bitronics interface, which allows bi-directional communication on the parallel port.

There are three MPS models which are the same except for the Ethernet interface used. The MPS1-T has an RJ45 port for 10BASE-T connections, the MPS1-2 has a BNC connector for 10BASE-2 connections, and the MPS100 can auto-negotiate between 10BASE-T and 100BASE-T media connected to its RJ45 port. The features, installation process, and con???guration procedures are the same.

NOTE: In this manual, all MPS models will be referred to as ???the MPS??? or ???the Server??? unless a distinction needs to be made between them.

1 - 1

Installation

1.Connect the MPS Centronics connector directly to your printer???s connector.

2a. For MPS1-T and MPS100 models, connect a twisted pair Ethernet cable to the MPS RJ45 connector.

2b. For MPS1-2 models, connect a thin coaxial Ethernet cable to the MPS BNC connector.

3.Attach one end of the power cable to the MPS; plug the other end into an electrical outlet. Power will come on automatically.

NOTE: The LINK LED indicates a good network connection. The ACT LED gives information about what the MPS is doing; for example, when code is being downloaded as the unit boots, the LED will blink green quickly.

Allow 45 seconds for the unit to fully boot. The LINK LED will be lit if there is a valid connection to the network, and the ACT LED should blink.

4.Print a Test page by pressing the Test/Reset button.

NOTE: If the Test page does not print, refer to Appendix B, Troubleshooting.

5.Install EZWebCon on your 32-bit Windows PC to con???gure your Server. The EZWebCon software is located on the CD-ROM. See EZWebCon Con???guration on page 3-2 for more information.

Getting Started

3 - Getting Started

It is important to consider the following points before logging into and con???guring the MPS:

???The MPS IP address must be con???gured before any TCP/IP functionality is available. (See Setting the IP Address on page 4-2.)

???There are two important passwords on the MPS: the privileged password and the login password.

Changing any server, service, or port setting requires privileged user status. The default privileged password is system.

The login password is required for remote console logins. The default login password is access.

NOTE: If you would like to change either the privileged or login password, either use EZWebCon or refer to the Print Server Reference Manual located on the CD-ROM.

3 - 1

Getting Started

3.1 EZWebCon Con???guration

The EZWebCon con???guration software is the recommended way to con???gure the MPS. EZWebCon is a graphical user interface that guides ???rst time users through the initial con???guration process and allows experienced users to update and change any con???gurable parameters. There are two important things to note about EZWebCon:

???Your Server must have an IP address before EZWebCon can log into it for con???guration purposes. See Setting the IP Address on page 4-2 for instructions.

???EZWebCon requires a Java Virtual Machine (JVM) on the client. Lantronix provides JVM installers for Solaris and 32-bit Windows users, as well as source code and instructions for compiling it for use on other systems.

The EZWebCon software is located on the distribution CD-ROM. All instructions for installing EZWebCon are provided in the README ???le. For assistance once EZWebCon is running, refer to the EZWebCon on-line help.

NOTE: EZWebCon is also available from the Lantronix FTP and BBS servers. See Appendix D for more information about logging into the FTP and BBS servers.

3 - 2

Getting Started

3.2 Incoming Logins

Incoming logins made via EZWebCon can be used to con???gure the server. Incoming LAT and TCP/IP logins can also be used.

Incoming Telnet is enabled by default to allow TCP/IP connections. To change this setting, use the De???ne Server Incoming command described in the Command Reference chapter of the Print Server Reference Manual located on CD-ROM.

Incoming logins do not prompt for a login password; therefore, you may wish to disable them. If it is undesirable to disable incoming logins, the Server can be con???gured to prompt for a password with the De???ne Server Incoming Password Enabled command.

3.3 Services

With few exceptions, a service must be created before print queues can be con???gured on the MPS. A service is a resource accessible to network hosts. A Lantronix service is also known as a remote printer name or remote queue name on many operating systems. The following 3 default services are available once the Server has booted:

TCP/IP Configuration

4 - TCP/IP Con???guration

The EZWebCon con???guration software is the easiest way to con???gure the MPS. The following sections cover IP address con???guration and print con???guration methods for TCP/IP hosts.

NOTE: The Server needs an IP address before you can use EZWebCon. See page 4-2 for instructions.

The MPS provides two major methods of printing via TCP/IP: Berkeley remote LPR and RTEL host software.

Neither Windows for Workgroups nor Windows 95 support LPR directly; however, there are third party solutions available. For more information about recommended peer-to- peer printing solutions, see the Lantronix Windows 95 FAQ on the CD-ROM or the Lantronix web site.

TCP/IP Configuration

4.1 Setting the IP Address

The MPS IP address must be con???gured before any TCP/IP functionality is available.

To set the IP address, use one of the following methods: EZWebCon; a directed Ping packet; a DHCP, BOOTP, or RARP reply; or commands entered at the command line (Local>) interface.

4.1.1 Using EZWebCon

The MPS must have an IP address before you can log into it using EZWebCon. To assign the IP address from EZWebCon:

1.Start EZWebCon. Instructions for installing, running, and using EZWebCon can be found on the distribution CD-ROM.

2.Click on the Lantronix logo menu in the bottom left corner of the EZWebCon win- dow, then select Assign IP Address to Server.

3.Fill in the following information:

A.The last three bytes of the MPS???s hardware address. The hardware address is printed on the bottom of the Server.

B.The desired IP address.

4 - 2

TCP/IP Configuration

C.The subnet, if you wish to use a subnet other than the default.

D.The IP address of the TFTP server you wish to use, if desired.

4.Click OK.

5.Cycle power on the server. EZWebCon will let you know whether the con???gura- tion was successful.

4.1.2 Using a Directed Ping Packet

The ARP/ping method is available under UNIX, Windows 95, and Windows NT. If the MPS has no IP address, it will set its address from the ???rst directed IP packet it receives.

NOTE: The ARP/ping method only works during the first two minutes of MPS operation. After two minutes, an alternate method must be used or the MPS must be rebooted.

On a UNIX host, create an entry in the host???s ARP table and substitute the intended IP address and the hardware address of the server, then ping the server. This process typically requires superuser privileges.

# arp -s 192.0.1.228 00:80:a3:xx:xx:xx % ping 192.0.1.228

4 - 3

TCP/IP Configuration

In order for the ARP command to work on Windows, the ARP table on the PC must have at least one IP address de???ned other than its own. If the ARP table is empty, the command will return an error message. Type ARP -A at the DOS command prompt to verify that there is at least one entry in the ARP table.

If there is no other entry beside the local machine, ping another IP machine on your network to build the ARP table. This has to be a host other than the machine that you're working on. Once there is at least one entry in the ARP table, use the following commands to ARP the IP address to the MPS and make the MPS acknowledge the IP assignment.

C:\ ARP -S 192.0.1.228 00-80-A3-XX-XX-XX

C:\ PING 192.0.1.228

NOTE: There should be replies from the IP address if the ARP command worked.

When the MPS receives the ping packet, it will notice that its IP address is not set and will send out broadcasts to see if another node is using the speci???ed address. If no duplicate is found, the server will use the IP address and will respond to the ping packet.

The MPS will not save the learned IP address permanently; this procedure is intended as a temporary measure to enable EZWebCon to communicate with the server, or allow an

administrator to Telnet into the MPS. Once logged in, the administrator can enter the Change IPaddress command to make the address permanent.

% telnet 192.0.1.228

Type Help at the ???Local_>??? prompt for assistance.

Enter Username> gopher

Local> SET PRIVILEGED

Password> system (not echoed)

Local>> DEFINE IPADDRESS 192.0.1.228

Any host wishing to access the MPS will have to be told the MPS???s IP address. This is typically con???gured in the unix ???le /etc/hosts or via a nameserver. Refer to the host???s documentation for additional information.

4 - 5

TCP/IP Configuration

4.1.3 Using a DHCP, BOOTP, or RARP Reply

At boot time a host-based DHCP, BOOTP, or RARP server can respond to an MPS request for an available IP address. For information about con???guring the DHCP, BOOTP, or RARP server, see your host documentation.

4.1.4Using the Command Line Interface

1.Connect to the serial port (Port 1) using a terminal emulation program. The serial settings should be 9600 baud, 8 bits, 1 stop bit, no parity.

2.Become the privileged user and enter the new IP address.

TCP/IP Configuration

4.2 Notes About LPR

There are four important things to note about the LPR printing method:

1.Because of the way the LPR protocol is typically implemented on the host, the processing options and banner page are sent after the job data itself. The MPS will print a banner page at the end of a job, and cannot support most of the LPR options. If it is necessary to have the banner page at the beginning of the printout, install and use the RTEL software. If banners are not needed, they can be disabled.

2.The MPS cannot print multiple copies of the print job when using the ???-#n??? lpr option.

3.If two print queues on the host refer to two services on the same MPS, they must use separate spooling directories.

4.No special purpose input or output ???lters can be used when printing via LPR. If this functionality is necessary, use the named pipe interface program in the RTEL print queue con???guration software.

4 - 7

TCP/IP Configuration

4.4 LPR on UNIX Hosts

The Berkeley remote printing system is supported on many machines, and is simple to con???gure.

This section describes how to con???gure LPR print queues on generic UNIX hosts such as SUN hosts. There are slight variations in LPR con???guration for AIX, HP, and SCO hosts, as will be explained in the following sections.

1.Install a print queue on your host by adding the MPS name and IP address to the

/etc/hosts ???le:

192.0.1.83MPS_xxxxxx

2.Add the host print queue to the /etc/printcap ???le:

mps_prt|Printer on LAB MPS:\ :rm=MPS_xxxxxx:\ :rp=MPS_xxxxxx_TEXT:\ :sd=/usr/spool/lpd/mps_prt:

The punctuation shown is required, and no extra spaces should be added.

4 - 15

TCP/IP Configuration

This will create a host queue named mps_prt. The rm parameter is the name of the MPS in the host's address file, the rp parameter is the name of the service as it exists on the MPS, and the sd parameter specifies the name of a directory used to hold temporary spooling files.

3.Create a world-writable spooling directory using the mkdir command.

#mkdir /usr/spool/lpd/mps_prt

#chmod 777 /usr/spool/lpd/mps_prt

4.If desired, use the mx option to allow unlimited size ???les to be printed and the sh option to prevent header pages from being generated. See the host's documenta- tion or man pages for more information on the format of the printcap ???le and how to create the spool directory.

5.Print to the queue using normal lpr commands:

%lpr -Pmps_prt /etc/hosts

4 - 16

TCP/IP Configuration

4.4.1 LPR on AIX Hosts

LPR has only been tested on AIX versions 3.2 and higher. The System Management Interface Tool (SMIT) allows you to enable LPD printing and create print queues.

To create a print queue:

1.At the host prompt type smit.

2.Choose Print Spooling.

3.Choose Manage Print Server and Start the Print Server Subsystem (lpd daemon).

4.In the Start the Print Server Subsystem dialog box, type both in the ???rst ???eld.

The message ???The lpd subsystem has been started??? will appear. Click Done. To add a print queue:

1.From the main window choose Print Spooling.

2.Choose Manage Print Server and Manage Print Queues.

3.Choose Add a print queue.

4.From the dialog box that appears choose remote.

4 - 17

TCP/IP Configuration

5.From the next dialog box choose Remote Printing.

6.The Add a Standard Remote Print Queue dialog box will appear. Enter the following information.

???The name of the print queue,

???The name of the MPS unit,

???The name of the MPS service,

???The type of print spooler on the remote server, and

???A description of the printer on the remote server.

A dialog box will appear with the message ???Added print queue mps_prt.???

NOTE: If you are unable to use SMIT, see the Print Server Reference Manual for UNIX commands for setting up print queues.

7.Print to the queue using normal lp syntax.

%lp -dmps_prt filename

4 - 18

TCP/IP Configuration

4.4.2 LPR on HP Hosts

The System Administration Manager (SAM) allows you to create print queues.

NOTE: If you are unable to use SAM, the Print Server Reference Manual located on the CD-ROM described UNIX commands that can be used to set up print queues.

To create a print queue:

1.At the HP prompt type sam.

2.From the main application window choose Printers and Plotters.

3.Choose Printers/Plotters from the Printers and Plotters window.

4.In the pull-down menu select Remote Printer/Plotter from the Actions menu.

5.The Add Remote Printer window will appear. SAM will prompt you for:

???The printer name (the name of the print queue),

???The remote system name (the MPS name),

???The remote printer name (the MPS service),

???The remote cancel model, and

???The remote status model.

4 - 19

TCP/IP Configuration

NOTE: Printer names on HP hosts are limited to 13 characters. The MPS text service name will be too long, so you will have to rename the Server.

4.4.3 LPR on SCO UNIX Hosts

LPR is supported in SCO V3.2 release 4 with TCP/IP Version 1.2 and greater.

To con???gure a print queue using LPR:

1.Issue the mkdev rlp command. This will install the Berkeley remote printing ???les and executable programs.

NOTE: The mkdev rlp command should only be issued once, or serious problems will occur. If this happens, contact SCO technical support.

You can print to this queue using normal lp syntax once the remote printer is set up.

To create a remote printer:

1.Issue the rlpconf command.

2.Answer the questions that follow. See the ???gure on the next page for more information.

Remote Printing Configuration

Enter information for remote printers or local printers accepting remote printing requests

Please enter the printer name (q to quit): backupprinter

Is printer backupprinter a remote printer or a local printer? (r/l) r

Please enter the name of the remote host that backupprinter is attached to: MPS_xxxxxx

The backupprinter is connected to host MPS_xxxxxx. Is this correct? (y/n) y

Would you like this to be the sys.default printer? (y/n) y

Make sure your hostname appears in MPS_PRT???s /etc/hosts.equivor or /etc/ hosts:lpd file.

Make sure backupprinter appears in /etc/printcap (in BSD format). Make sure backupprinter has a spool directory on MPS_PRT.

Putting the printer in printer description file and creating spool di- rectory... done

Updating LP information... done

The printer name is your MPS service name. The remote host name is the name of your MPS as it is listed in your hosts file.

During initial configuration, the queue name must be the same as the remote printer name. However, you may change the queue name later by manually editing the printcap file.

4 - 21

TCP/IP Configuration

4.5 RTEL Functionality

If the LPR method of printing is not adequate for an application (for example, if you need banners before jobs, or more ???exibility), con???gure the Lantronix-supplied RTEL software on the host. After installing the software con???guring the connections to the MPS, you can use normal UNIX print commands and queue utilities such as lpc and lpstat.

NOTE: RTEL binaries are provided for many systems. Source code is also pro- vided for use on non-supported systems.

To print to the MPS using special formatting or using third-party software packages, you may have to create ???print pipes??? on the host. The RTEL software provides this functionality by providing a UNIX named-pipe interface.

To recreate the RTEL source ???les:

1.Copy the ???le RTEL_SRC.TAR from the distribution CD-ROM to the UNIX host. Ensure that a binary copy is performed.

2.Untar the archive.

3.See the README ???les in the created directories that describe the contents of the RTEL distribution and man pages that describe the actual software functionality.

NetWare Configuration

5 - NetWare Con???guration

The EZWebCon con???guration software is the easiest way to con???gure the MPS. The following sections cover print con???guration methods for NetWare hosts.

NOTE: The Server needs an IP address before you can use EZWebCon. See the Setting the IP Address section on page 4-2 for instructions.

This chapter explains creating NDS print queues with NetWare Administrator and with the PCONSOLE Quick Setup option. To create NDS print queues, you must be running NetWare version 4.x with NDS capabilities.

If you are running NetWare versions 2.x, 3.x, or version 4.x with bindery emulation, you may con???gure bindery print queues using QINST (bindery only) or PCONSOLE. For more information, see the NetWare chapter of the Print Server Reference Manual, located on CD-ROM.

5.2 Creating Print Queues Using NetWare Administrator Quick Setup

The NetWare Administrator management utility allows you to manage network resources, such as queue-based print services, in a tree structure. You can either use the Quick Setup option or individually create printing-related objects.

To create a print queue with the Quick Setup option.

NOTE: NetWare Administrator can be used for both NDS and bindery print queues.

1.Start NetWare Administrator.

2.In the Directory Tree windows, select the context in which to install the printer.

3.From the Menu Bar, select Tools: Print Services Quick Setup.

4.In the Print Server Name ???eld, enter the name of your Lantronix server (viewable by entering the Show Server command at the Local> prompt).

5.In the Printer Name ???eld, enter the name of the desired print service con???gured on your Lantronix server.

6.In the Print Queue Name ???eld, enter the name of the print queue to create. The name should be meaningful to you; it will not affect Server con???guration.

7.Click Create.

8.Reboot the MPS.

5 - 4

NetWare Configuration

5.3Creating NDS Print Queues Using PCONSOLE

1.Log in as Admin on the ???le server you will be changing.

2.Type PCONSOLE at the X: prompt to start the utility.

For example, if your file server is mapped to the F: drive, you would use the F: prompt.

3.From the main menu choose Quick Set-Up.

4.PCONSOLE will prompt you for information with which to con???gure the print queue.

The print server name is the name of your MPS (MPS_xxxxxx). The new printer name is the service name (for example, MPS_xxxxxx_Text). The new print queue can be any name. The print queue volume is the name of the file server from which the printer receives print requests. The remaining fields can be left in their default settings.

NOTE: In the above text, xxxxxx represents the last 6 digits of your MPS???s hardware address. The hardware address is printed on the unit???s label.

5.Press the F10 key to save the print queue information.

6.Reboot the MPS.

5 - 5

LAT Configuration

6 - LAT Con???guration

The EZWebCon con???guration software is the easiest way to con???gure the MPS. The following sections cover print con???guration methods for LAT hosts.

NOTE: The Server needs an IP address before you can use EZWebCon. See the Setting the IP Address section on page 4-2 for instructions.

LAT print queues can be created by printing to a port or printing to a service. Printing directly to a port requires no MPS con???guration.

NOTE: Printing directly to a port is the easiest method for printing to the MPS. If you would like instructions for printing to a service, see the Print Server Reference Manual on the CD-ROM.

6.1Printing Directly to a Port

1. Create a LAT application port that references the Server port.

$ RUN SYS$SYSTEM:LATCP

LATCP> CREATE PORT LTAnnn/APPLICATION

LATCP> SET PORT LTAnnn/NODE=MPS_xxxxxx/PORT=Port_n

LATCP> EXIT

LAT Configuration

6.1.1 LAT Host Troubleshooting

By default, the LAT error message codes on the host are not translated into text error messages. If a LAT job fails and appears in the queue with an eight-digit hex result code, the code can be translated by issuing the following commands:

$ SHOW QUEUE/FULL/ALL queue_name (note the error code nnnnnnnn)

$ SET MESSAGE SYS$MESSAGE:NETWRKMSG.EXE $ EXIT %Xnnnnnnnn

Table 6-1: Troubleshooting LAT Con???gurations Using a Port

The speci???ed node name matches the Server???s node name

The speci???ed port name matches the port???s name

Use the Show Server command.

Use the List Port 1 command.

AppleTalk Configuration

7 - AppleTalk Con???guration

The EZWebCon con???guration software is the easiest way to con???gure the MPS. The following sections cover print con???guration methods for AppleTalk hosts.

NOTE: The Server needs an IP address before you can use EZWebCon. See the Setting the IP Address section on page 4-2 for instructions.

NOTE: Macintoshes that do not support EtherTalk will need either an Ether- net card or a LocalTalk-to-EtherTalk router to use the MPS.

7.1 Bitronics

The MPS advertises its printer as a LaserWriter. Therefore, printing from a Macintosh is only possible with a PostScript printer and bi-directional communication between the MPS and that printer.

NOTE: MacOS 8.1 can also print via LPD. See the Print Server Reference Manual located on CD-ROM for configuration instructions.

The MPS supports the Bitronics interface, an extension to the standard Centronics interface. Printers that support Bitronics allow bi-directional communication via the parallel port. To enable Bitronics on the MPS parallel port, use the De???ne Port 1 Bitronics Enabled command.

7 - 1

AppleTalk Configuration

7.2 Macintosh Services

Before attempting to print from a Macintosh, ensure that AppleTalk and PostScript are both enabled on at least one service. Once the service is con???gured, it will appear in the Chooser in the same zone as the MPS. Select the service in the Chooser and complete the appropriate setup options. Then close the Chooser window and print a test page of text to the Macintosh service.

7.3 AppleTalk Zones

If there is a router on the network, the MPS will appear in the default zone speci???ed by the router. To change the default zone use the De???ne Protocol AppleTalk Zone command.

If the MPS is attached to a network without an AppleTalk router, all AppleTalk devices (including the MPS) will appear in the default zone in the Chooser.

NOTE: If no router is present on the network, the MPS will not accept AppleTalk print jobs for 60 seconds after booting.

LAN Manager/DLC Configuration

8 - LAN Manager/DLC Con???guration

The EZWebCon con???guration software is the easiest way to con???gure the MPS. This chapter explains DLC con???guration for Windows NT 4.x hosts. Windows 95 does not support DLC printing (see Chapter 4, TCP/IP Con???guration, for more information).

NOTE: The Server needs an IP address before you can use EZWebCon. See the Setting the IP Address section on page 4-2 for instructions.

NOTE: Printing using an LPD client is the preferred method for sending print jobs to the MPS. To print using the TCP/IP protocol see the Using the Command Line Interface section on page 4-8.

8.1 DLC Con???guration

8.1.1 Server Con???guration

To use the DLC protocol, you must have one service with the DLC characteristic enabled. Use the De???ne Service servicename DLC Enabled command. The DLC characteristic may be associated with only one service on a given MPS.

Troubleshooting

B.4 DHCP Troubleshooting

Table B-4: DHCP Troubleshooting

DHCP is enabled on the Server.

Make sure the DHCP server is operational.

Did the Server get its IP address from the DHCP server?

Use the De???ne Server DHCP Enabled command.

If you manually enter an IP address, DHCP is automatically disabled.

Check to see that the DHCP server is on and is functioning correctly.

Refer to the DHCP Manager on your DHCP server for information about addresses currently in use. If the DHCP server does not list your Server???s IP address, there may be a problem.

D.2 Updating Using FTP

The server software resides on the Lantronix FTP server (ftp.lantronix.com). Most of these ???les are binary data, so the binary option must be used to transfer the ???les. All released ???les are in the pub directory. Always download the README ???le in the pub directory before downloading anything else; it contains a directory of available versions.

To log into the FTP server, enter a username of anonymous and enter your full email address as the password. The following text will be displayed:

230-Welcome to the Lantronix FTP Server.

230-

230-IMPORTANT: Please get the README file before proceeding.

230-IMPORTANT: Set BINARY mode before transferring executables.

D.3 Updating Using the BBS

The Lantronix system uses high speed modems for the physical connection and allows ???le transfers using KERMIT, xmodem, ymodem, and zmodem. The modem phone number is (949) 367-1051. The account name is ets and the password is server.

Remember that the download ???les (MPS.SYS) and executable images are image data and should only be transferred in binary mode, otherwise the ???les will be corrupted.

D.4 Reloading Software

The Server stores software in Flash ROM to control the initialization process, operation, and command processing. The contents of Flash ROM can be updated by downloading a new version of the operational software via NetWare, TCP/IP, or MOP. Regardless of which protocol is used to update Flash ROM, the following points are important:

???The Flash ROM software is contained in a ???le called MPS.SYS. The name should not be changed.

???The download ???le should be world-readable on the host.

???There is a sixteen character length limit for the path name.

???There is a twelve character limit for the ???lename.

D - 4

Updating Software

???De???ne commands must be used because Set con???gurations are cleared when the Server boots. Use the List Server Boot command to check settings before rebooting.

NOTE: It is very important to check the Server settings before using the Initialize Reload command to ensure that you are reloading the correct software file.

D.4.1 Reloading Sequence

If DHCP, BOOTP, or RARP is enabled on the Server, the Server will request assistance from a DHCP, BOOTP, or RARP server before starting the download attempts. The Server will then try TFTP, NetWare, and MOP booting, in that order, provided that it has enough information to try each download method.

Downloading and rewriting the Flash ROM will take approximately two minutes from the time the Initialize command is issued. If the download ???le cannot be found or accessed, the Server can be rebooted with the code still in Flash ROM. As noted in Chapter 2, the OK/ACT LED will blink quickly while the Server is booting (and reloading code) and then slowly when it returns to normal operation.

NOTE: If you experience problems reloading Flash ROM, refer to Troubleshooting Flash ROM Updates on page D-9.

D.4.2 NetWare

The MPS.SYS ???le should be placed in the login directory on the NetWare ???le server. The Server cannot actually log into the ???le server (since it knows no username/password); it can only access ???les in the login directory itself. On the Server, specify the ???le server name, ???lename, and path.

Local> SET PRIVILEGED

Password> SYSTEM (not echoed)

Local>> DEFINE SERVER NETWARE LOADHOST fileserver

Local>> DEFINE SERVER SOFTWARE SYS:\LOGIN\ MPS.SYS

Local>> INITIALIZE RELOAD

D.4.3 TCP/IP

Before the Server downloads the new software, it will send DHCP, BOOTP, and/or RARP queries (BOOTP and RARP queries are enabled by default). Next, the Server will attempt to download the MPS.SYS ???le using TFTP (Trivial File Transfer Protocol).

If a host provides DHCP, BOOTP, or RARP support, it can be used to set the Server's IP address (all) and loadhost information (BOOTP and RARP only). Add the Server's name,

Updating Software

IP address, hardware address, and download path and ???lename to the appropriate host ???le (usually /etc/bootptab).

Some BOOTP and TFTP implementations require a speci???c directory for the MPS.SYS ???le; in this case the path should not be speci???ed in the bootptab ???le and the ???le must be placed in that directory. See your host???s documentation for instructions on how to con???gure the MPS.SYS ???le in the directory.

If BOOTP cannot be used to con???gure the Server's IP parameters, con???gure them by hand using the following commands listed below.

Local> SET PRIVILEGED

Password> SYSTEM (not echoed)

Local>> DEFINE SERVER IPADDRESS nnn.nnn.nnn.nnn

Local>> DEFINE SERVER SOFTWARE ???/tftpboot/ MPS.SYS???

Local>> DEFINE SERVER LOADHOST nnn.nnn.nnn.nnn

Local>> LIST SERVER BOOT

Local>> INITIALIZE RELOAD

NOTE: For instructions on how to log into the Server and enter these commands, refer to Chapter 6, TCP/IP Configuration.

Updating Software

The path and ???lename are case-sensitive and must be enclosed by quotation marks. When attempting to boot across an IP router, you must con???gure the router to proxy- ARP for the Server, or use the bootgateway feature. For more information, see Set/De???ne Bootgateway in the Commands chapter of the Print Server Reference Manual on CD-ROM.

D.4.4 MOP

Copy the MPS.SYS ???le to the MOM$LOAD directory. The MPS.SYS ???lename is the only parameter that the Server needs to reload via MOP. Make sure the service characteristic is enabled on the host's Ethernet circuit, and then reload the server using the Initialize Reload command.

NOTE: If an error message is displayed indicating an invalid record size on the VAX console, the MPS.SYS file was not transferred in binary mode.
