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.
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.
. . . . . . . . . . . . . . . . . . . .
This Class A digital apparatus meets all requirements of the Canadian Interference-
Causing Equipment Regulations.
Cet appareil numérique de la classe A respecte toutes les exigences du Règlement sur le
matériel brouilleur du Canada.
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.
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.
. . . . . . . . . . . . . . . . . . . .
Products with the CE Marking comply with both the EMC Directive (89/336/EEC) and
the Low Voltage Directive (73/23/EEC) issued by the Commission of the European
Community.
Compliance with these directives implies conformity to the following European Norms
(in brackets are the equivalent international standards):
■ EN55022 (CISPR 22) - Electromagnetic Interference

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.
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
. . . . . . . . . . . . . . . . . . . .
Figure 1-1 shows the repeater with the following options: basic configuration
with eight RJ-45 ports; AUI configuration (the AUI connector is located on
the back panel); the BNC and UTP configurations with BNC and UTP

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

This chapter describes the basic requirements for setting up the repeater,
including environmental, electrical, and spatial requirements, as well as UTP
cabling specifications. It also explains how to power up the repeater, how to
make a basic repeater-to-workstation connection, and how to set up basic
network configurations.
You can place the repeater on a level surface (a desktop or cabinet, for
example) or mount it on a vertical surface using velcro attachments. Before
you select a location for the repeater, read this section to determine the
necessary environmental, electrical, and spatial requirements.
Be sure the operating environment for the repeater is within the
following ranges:
■
Temperature: 32° to 120° F; 0° to 49° C
■
Humidity: 5% to 95% (non-condensing)
■
Altitude: 0 to 30,000 feet; 0 to 10,000 meters
Be sure there is a commercial power outlet within 6 feet (1.8 meters) cord
distance of the repeater. If there is no outlet within this distance, use a power
strip or grounded extension cord to extend the range of the power cable. The
power outlet must be a non-switched, three-pronged, grounded outlet. The
electrical requirements for the repeater, see Appendix A, “Technical
Specifications” in this guide.
. . . . . . . . . . . . . . . . . . . .
The repeater's dimensions are 4.0 x 7.0 x 5.0 inches or 10.2 x 17.9 x 12.8 cm
(HxWxD). When you set the repeater on a level surface, allow at least
2 inches (5.1 cm) on each side of the repeater for proper air circulation.
If you place the repeater on a level surface, the rubber feet (attached to the
bottom of the repeater) help protect the surface and prevent the repeater
from slipping.
The domestic and international power connections differ for the repeater.
Each is described below.
To connect the repeater to external, domestic power, follow
these steps:
1. Locate the power cord connector on the back of the repeater, as shown
in Figure 2-1.

3. Insert the three-pronged plug on the other end of the power cord into a
non-switched, grounded power outlet on a wall, a power strip, or a
grounded extension cord. The power outlet should be near the repeater
and easily accessible (within the 6-foot, 1.8 meter, cord distance).
4.
When you restart the repeater, all the LEDs on the front panel
momentarily turn ON. This confirms that the repeater is working.
To connect the repeater to external, international power, follow
these steps:
1. Place the international power transformer (supplied) on a
flat surface.
2. Insert the plug on the power transformer cable into the power outlet in
the back of the repeater. Be sure the lip on the power plug faces the top
of the repeater (as illustrated for domestic connections in Figure 2-2).
3. Insert the plug of the IEC power cord into the three-pronged, power
transformer outlet, as shown in Figure 2-3:

This section outlines twisted-pair wire specifications and describes how to
make a simple direct connection between a repeater and a workstation.
To ensure long-term LAN reliability, be sure that the twisted-pair wiring
meets the following minimum specifications. You may need to install new
twisted-pair wiring if the wiring does not meet the following requirements:
■
The wiring must be shielded or unshielded twisted-pair (STP/UTP).
■
Two pairs of wires
■
Depending on building codes, different insulation materials may be
required. Plenum-rated or Teflon-coated wiring may be required in some
areas.
■
The UTP wire should meet the following specifications:
❏
Solid copper
❏
Nominal capacitance: Less than 16pF/foot
❏
Nominal impedance: 100 Ohms
❏
Nominal attenuation: Less than 11.5db
❏
Wire gauge: Between 18 and 26 AWG
■
The wiring has a maximum distance requirement of 328 feet (100
meters), which includes all cross-connect wire, wire in the walls, and
any drop cables from wall plates to workstations (see the next section to
determine the proper length). Maximum distances may be less for UTP
cable run underground, in conduit, or in large cable bundles.
■
The wiring must be in good condition and the insulation should not be
frayed or worn.
. . . . . . . . . . . . . . . . . . . .
The repeater is compatible with all AT&T Type D wiring (D-Inside wiring)
and AT&T PDS wiring. You can also use IBM Type 1 wiring (with two
inside conductors).
Two types of D-Inside wiring will work with the repeater:
A modular cord is D-Inside wiring with RJ-45 plugs on each end. The
connection between a repeater and a workstation consists of four pairs of
straight-through, D-Inside wiring (the repeater uses only two pairs), as shown
in the following figures:
Brown-White 8
White-Brown 7
Green-White 6
Blue-White 5
White-Blue 4
White-Green 3
Orange-White 2
White-Orange 1

7 White-Brown
8 Brown-White
. . . . . . . . . . . . . . . . . . . .
In this cable, the wire connected to Pin 1 must be twisted with the wire
connected to Pin 2, and the wire connected to Pin 3 must be twisted with the
wire connected to Pin 6. This is shown in Figure 2-5. Pins 4, 5, 7, and 8 are
reserved for telephone and other services.

Each RJ-45 jack on the repeater has the 10Base-T standard pin-out
shown below. A straight-through cable using the pair combinations
below provides the appropriate 10Base-T connection between the
repeater and the workstation.
. . . . . . . . . . . . . . . . . . . .
To connect the repeater to a workstation, follow these steps:
1. Plug one end of the modular cord into a 10Base-T-equipped workstation.
2. Plug the other end of the modular cord directly into the desired port on
the repeater. The maximum end-to-end cable distance is 328 feet
(100 meters).
After you connect the workstation to the repeater and power on both
units, the repeater's PWR LED and the LED that corresponds to the
connected RJ-45 port should be ON. If the LEDs are not ON, check
the connections.
