Federal Communications Commission Notice
Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has
established Radio Frequency (RF) emission limits to provide an interference-free radio
frequency spectrum. Many electronic devices, including computers, generate RF energy
incidental to their intended function and are, therefore, covered by these rules. These
rules place computers and related peripheral devices into two classes, A and B,
depending upon their intended installation. Class A devices are those that may
reasonably be expected to be installed in a business or commercial environment. Class B
devices are those that may reasonably be expected to be installed in a residential
environment (i.e., personal computers). The FCC requires devices in both classes to bear
a label indicating the interference potential of the device as well as additional operating
instructions for the user.
The rating label on the device shows which class (A or B) the equipment falls into. Class
B devices have an FCC ID on the label. Class A devices do not have an FCC ID on the
label. Once the class of the device is determined, refer to the following corresponding
statement.
NOTE:
If this equipment contains a Token Ring interface, this equipment is a Class A digital
device when the Token Ring interface is utilized.
Class A Equipment
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at personal expense.

Canadian Notice
This Class A digital apparatus meets all requirements of the Canadian Interference-
Causing Equipment Regulations.
Avis Canadien
Cet appareil numérique de la classe A respecte toutes les exigences du Règlement sur le
matériel brouilleur du Canada.
Modifications
The FCC requires the user to be notified that any changes or modifications made to this
device that are not expressly approved by Compaq Computer Corporation may void the
user's authority to operate the equipment.
Cables
Connections to this device must be made with shielded cables with metallic RFI/EMI
connector hoods in order to maintain compliance with FCC Rules and Regulations.

Chapter 1
Overview
The Compaq Netelligent 1008/1009 10Base-T unmanaged repeaters are the
ideal connectivity solution for departmental Ethernet networks that contain
8 to 32 nodes. The repeaters are easy to configure and maintain, plus each
has built-in port management.
More importantly, the four repeater versions (basic, AUI, BNC, and UTP) let
you expand your network to other configurations without sacrificing your
existing network configuration. For example, if you currently have a 10Base-
T RJ-45 backbone network, you can easily add eight inexpensive UTP ports
by choosing the basic repeater version. In the same way, you can connect a
10Base-5 (AUI) or a 10Base-2 (BNC) backbone network to your choice of
configurations by selecting the appropriate Netelligent 1000 repeater version.
You can even add a ninth 10Base-T port with the UTP repeater version.
Features
The repeater has the following features:
■ A basic configuration that contains eight RJ-45 ports for connecting
UTP or STP cabling to workstations and servers in a 10Base-T network;
optional connectors are available, making a total of nine ports
■ AUI connector (optional) for connecting to 10Base-5 networks
■ BNC connector (optional) for connection to 10Base-2 networks
■ UTP connector (optional) adds a ninth 10Base-T port
■ Front panel uplink switch converts RJ-45 Port 8 to an uplinkable port,
which lets you connect two repeaters in a star topology
■ LEDs indicate power, port activity, collision, and link status
■ Link integrity feature automatically partitions noisy segments and
detects broken cable segments
■ Compatible with the IEEE 802.3 10Base-T repeater specifications for
connection to shielded/unshielded twisted-pair wiring

LED Indicators
The repeater contains the following LEDs that monitor repeater status:
■ PWR, ACT, COL, and 9X — these LEDs show the repeater's power
status (ON or OFF), the incoming traffic on the repeater (heavy, light, or
no activity), and the collision status (heavy or light activity); the 9X
LED is for the optional UTP port.
■ Link Status — Each RJ-45 port is associated with a Link Status LED
that operates in the following manner:
❏ When you power up the repeater, the Link Status LEDs are ON
momentarily, then are OFF.
❏ When the repeater connects with either a powered network station
or another repeater, the Link Status LED associated with that port is
ON. When the connection breaks, the LED is OFF.
❏ If the repeater makes no connection, the Link Status LED is OFF.
The following illustration shows the locations of the LEDs and the
RJ-45 ports on the front panel of the repeater. Table 1-1 describes the
meaning of each LED display.
