Hub Components

This section provides an overview of the Compaq HB1004 hub’s components including the LED indicators, RJ-45 ports, and the serial COM port. Figure 1-1 shows the hub’s 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.
