Figure 1-1 Compaq HB1004 10Base-T Ethernet Hub Front Panel

RJ-45 Ports

The hub???s four RJ-45 ports allow connections to workstations and servers in a 10Base-T network via UTP cabling. When the MDI/MDI-X slide switch on the front panel of the hub is set to MDI, Port 4 uses the MDI pinout and can be used for a 10Base-T uplink. When the switch is set to MDI-X, Port 4 uses the MDI-X pinout and can be connected directly to a network interface card (NIC).

Serial COM Port

The HB1004 hub contains a serial COM port that uses a male DB9 connector with a standard AT pinout. You can use this port to connect to a workstation for out-of-band communication using the Compaq HB1004 System Configuration Program.

LED Indicators

The LED panel of the hub helps you monitor the hub???s operation. When you power on the hub, it performs a power-on self test (POST) which lasts a few seconds. After the POST, all LEDs reflect the current operational modes described in Table 1-1.

Setup and Configuration

Preparing for Configuration

Management

There are two methods for configuring the Compaq HB1004 - using the out-of- band program or using in-band network management software (not supplied). The diskette included with the Compaq HB1004 contains the menu-driven Compaq HB1004 System Configuration Program. To use this program, make a direct PC or modem connection to the serial port on the front of the hub.

Out-of-Band Connection

Out-of-band configuration requires a computer as your workstation. There are two valid connection types to the hub:

QOut-of-band onsite connection - The workstation, normally within the vicinity of the hub, is directly connected to the serial port on the hub.

QOut-of-band modem connection - The workstation is connected to the remote hub via a modem.

Onsite Connection

Attach a PC to the serial port on the hub. Use the communication cable (and DB9 to RJ-45 converters) provided with this package. Configure the PC???s serial port for 9600 baud, 8 bits, no parity, and one stop bit (9600, 8, N, 1). See Figure 3-1.

NOTE: Some PCs may have a 25 pin serial port. For these PCs use the DB25 to RJ-45 converter supplied with the hub instead of the DB9 to RJ-45 converter mentioned above to connect the PC.

B-2 Troubleshooting

Power and Cooling Problems

If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fan on back of the unit was unobstructed and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, contact Compaq Technical Support at 1678-23143.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g., the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

Port and Cable Assignments

RJ-45 hub ports (MDI-X) can be attached to any device that uses a standard network interface (e.g., a workstation or server). Similar networking devices (e.g., another hub or switch) can be cascaded by connecting any of the RJ-45 ports (MDI-X) on the HB1004 hub to an MDI port on the other device. You can also set Port 4 on the HB1004 hub to MDI and connect to an MDI-X port on the other device. Use 100?? Category 3, 4, or 5 twisted-pair cable, unshielded or shielded (UTP/STP), for all RJ-45 connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).
