Chapter 1
Overview
The Compaq HB1004 10Base-T Ethernet Hub is a stand-alone, intelligent, 4
port hub. If offers an SNMP V1-compliant firmware agent. The HB1004 can
be monitored and controlled through a network management station. In
addition, you can also cascade the hub to additional 10Mb/s hubs or
10/100Mb/s switches.
The hub supports both in-band and out-of-band management. For in-band
management you can use SNMP compliant network management software to
monitor and control the system. For out-of-band management, you can connect
the hub’s RS232 port to a PC running the Compaq HB1004 System
Configuration Program.
Features
QFour RJ-45 10Base-T ports
QIEEE 802.3 compliant
QProvides one DB9 connector RS232 port for out-of-band network
management using the Compaq HB1004 System Configuration Program
QOne port is selectable to provide either MDI or MDI-X support
QSupports automatic polarity detection and correction, permitting
automatic recovery due to wiring errors
QAutomatically auto-partitions bad ports to protect normal network
operation
QAutomatically adapts to a wide range of power sources
QCan be mounted on a desktop or in a standard 19” rack
QIncludes a comprehensive LED indicator panel for reporting network
activity, unit configuration, and problem diagnosis
QSNMP support including MIB-II, repeater MIB, and Compaq private
MIB
QSupports FlashROM on board for easily updating the microcode using
TFTP or the Compaq HB1004 System Configuration Program running
on a PC

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.

Unit LEDs
The unit-level LEDs on the HB1004 indicate the status of the power supply and
the percentage of use and collisions on the hub.
Table 1-1
Hub LED Conditions and Descriptions
LED Status Description
Power On Power supply is operational
Off Power supply is off
Utilization Indicates percentage of network utilization
1 Green lit 1% to 5%
2 Green lit 5% to 15%
3 Green lit 15% to 30%
3 Green, 1 Amber lit 30% to 65%
3 Green, 2 Amber lit Above 65%
Collision Indicates percentage of network collision count variation
1 Green lit 1% to 3%
2 Green lit 3% to 5%
3 Green lit 5% to 10%
3 Green, 1 Amber lit 10% to 15%
3 Green, 2 Amber lit Above 15%

Port LEDs
There are two LEDs for each port to indicate link/activity and partition/disable
on the ports.
Table 1-2
Port LED Conditions and Descriptions
LED Status Description
Link/Activity Solid green A network device has established a link with the hub
Flashing green Data is passing through the port, flashes in proportion to
rate of traffic passing through the port
Partition/Disable Solid Amber Indicates the port is partitioned
Flashing Amber Indicates the port has been disabled by management
Off The port is operating normally
MDI/MDI-X Slide Switch
The MDI/MDI-X slide switch is located on the front panel of the hub. This
switch allows you to use Port 4 as an uplink port to connect the hub to another
hub or switch. When the switch is in the MDI position, Port 4 uses the MDI
pinout for an uplink port. When the switch is in the MDI-X position, Port 4
uses the MDI-X pinout to connect to a workstation or server NIC.
