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 100Category 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.

WARNING: Do not plug a phone jack connector into any RJ-45 port.  
This may damage the hub. Instead, use only twisted-pair cables with  
RJ-45 connectors.  
NOTES: 1. Make sure each twisted-pair cable does not exceed 100 meters (328 feet)  
2. When using Port 4 as an MDI-X port, set the port selection switch to MDI-X  
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 100Category 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).

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.

Configuration  
The Compaq HB1004 provides a proprietary, user-friendly, menu driven out-  
of-band program (Compaq HB1004 System Configuration Program). This  
program allows you to configure the hub using a PC directly attached to the  
RS232 port on the front of the hub, or remotely via a modem connected to the  
RS232 port. With this program you can define system parameters, manage and  
control the hub and associated ports, and monitor network conditions. Table 3-1  
briefly describes the menu selections available for this program.

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 100Category 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).
