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

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

Troubleshooting
Diagnosing Hub Indicators
The hub can be easily monitored through panel LED indicators to assist the
network manager in identifying problems. This section describes common
problems you may encounter and possible solutions.
Table B-1
Diagnosing Hub Indicators
Symptom Cause Solution
Power indicator does not light
up (green) after power on
Defective power outlet, power
cord, or internal power supply
Check the power outlet by plugging in another
device that is functioning properly. Check the
power cord with another device. If these
measures fail to resolve the problem, contact
Compaq Technical Support at 1678-23143
Link indicator does not light
up (green) after making a
connection
Network interface (e.g., a network
adapter card on the attached
device), network cable, or hub
port is defective
Verify that the hub and attached device are
powered on. Be sure the cable is plugged into
both the hub and attached device. Check the
adapter on the attached device and cable
connections for possible defects. See if your
cable is functioning properly by using it for
another port and attached device that displays
valid indications when connected to the
network. Replace the defective adapter or
cable if necessary. Also verify that you have
not exceeded specified limits for any attached
media.

Troubleshooting
B-2
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 100Ω 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).
