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.

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.

Connecting the Hub System

The Compaq HB1004 hub has four RJ-45 ports, one of which serves as an

MDI/MDI-X port.

Making a Connection via an MDI-X Port

You can connect any RJ-45 (MDI-X) station port on the hub to any device that

uses a standard network interface such as a PC or server. You can also connect

to an MDI-X port of a network interconnection device such as a bridge or router

by using a cross-over cable.

1. Prepare the network devices you wish to network. Make sure you have

installed 10Base-T network interface cards for connecting to the hub’s

RJ-45 (MDI-X) station ports. You also need to prepare straight-through

shielded or unshielded twisted-pair cables with RJ-45 plugs at both ends.

Use 100Ω Category 3, 4, or 5 cable for all RJ-45 connections.

2. Connect one end of the cable to the RJ-45 port of the network interface

card, and the other end to any available (MDI-X) station port on the hub.

When inserting an RJ-45 plug, be sure the tab on the plug clicks into

position to ensure that it is properly seated. Using the hub in a stand-

alone configuration, you can network up to four end nodes.

Making a Connection via the MDI/MDI-X Port

(Port 4)

1. To make a direct connection to a compatible hub or switch, use the

MDI/MDI-X port (Port 4). When connecting to this port, remember to

set the port selection switch to MDI. You can also connect any RJ-45

(MDI-X) port on the hub to an MDI/MDI-X port on the other device

when the other device’s port is set to MDI.

2. Prepare straight-through shielded or unshielded twisted-pair cables with

RJ-45 plugs at both ends. Use 100Ω Category 3, 4, or 5 cable for all RJ-

45 connections. When inserting an RJ-45 plug, be sure the tab on the

plug clicks into position to ensure that it is properly seated.

NOTES:

1. To connect to another hub or switch, you may also attach to (MDI-X)

station ports at both ends if you use a crossover cable.

2. When using Port 4 as an MDI port, set the port selection switch to

MDI.

3. When connecting to another 10Mb/s hub, you can cascade up to four

hubs, and use up to 100 meters (328 feet) of cable between each

inter-hub link.

Powering On the Hub

1. Plug the power cord into the power socket at the rear of the hub, and the

other end into a power outlet (see Figure 2-4).

Diagnostic Tests

After power on, the hub automatically performs a diagnostic self-test. During

this test, port status LEDs indicate the success or failure of each test.

The system tests each component one at a time. At the completion of the test, if

no diagnostic LEDs are lit, then all components passed the test. If a component

fails the test, the corresponding LED will continue blinking. The following

table identifies the component that corresponds to each diagnostic test LED.

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:

Q

Out-of-band onsite connection - The workstation, normally within the

vicinity of the hub, is directly connected to the serial port on the hub.

Q

Out-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.
