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
Compaq Netelligent 2524, 2624, 3512, and 3612 100Base-T repeaters are
designed to bring reliable 100 Mb/s performance to your desktop. Compaq
Smart Uplink technology lets you interconnect managing versions of these
repeaters (Models 2624 and 3612) to increase the diameter of your network
beyond the normal limitations set by 100Base-T Class 1 specifications. You can
also integrate the repeater into your existing 10Base-T network using a switch,
bridge, or router. These repeaters offer a wide array of features for a versatile,
low-cost stackable repeater solution.
These Netelligent repeaters are available in the following models:
Netelligent 2524 — 24-port unmanaged 100Base-TX repeater
(Part Number 267001-001)
Netelligent 2624 — 24-port managing 100Base-TX repeater
(Part Number 267000-001)
Model 3512 — 12-port unmanaged 100Base-TX repeater
(Part No. 267008-001)
Model 3612 — 12-port managing 100Base-TX repeater
(Part No. 267007-001)
Features
These Netelligent repeaters provide these features:
24 RJ-45 ports for 2524/2624; 12 RJ-45 ports for 3512/3612
One Smart Uplink slot for a Smart Uplink module (SUM) and one
console port for Telnet and TFTP (Models 2624 and 3612 only)
24 bi-colored LED indicators (12 for Models 3512 and 3612) show port
activity, port link, and port disable/auto partition; other LEDs show
collisions, the power supply status, and the management status of the
repeater

Smart Uplink capability extends the distance between repeaters to up to
100 meters/328 feet (or 412 meters/1352 feet with fiber). This allows
integration of multiple 100 Mb/s repeaters into an existing 100Base-T
configuration without normal repeater hop limitations.
TX, FX (ST), and FX (SC) Smart Uplink modules available
Four-group RMON (Remote MONitor) support allows remote diagnostic
monitoring via the network management system (Model 3612 only)
Fast Ethernet wiring standards ensure compatibility with all types of
UTP cabling
2524/2624 repeaters are stackable up to three units high (as long as the
stack contains a 2624 model), providing up to 72 workstation
connections. The 3512/3612 repeaters are stackable up to five units high
(as long as the stack contains a 3612 model), providing up to 60
workstation connections.
2524/2624 repeaters allow one backplane segment per stack, connected
via a backplane connection cable (Part No. 283305-001).
3512/3612 repeaters are segmentable on a per-unit basis; or, by
interconnecting repeaters with a FlexPlane backplane connection cable
(Part No. 810172-000), all repeaters in a stack can share up to three
common backplane segments.
Host/target design allows unmanaged repeaters (Models 2524 or 3512)
to be managed by a single managing repeater (Models 2624 or 3612).
2524 and 2624 repeaters provide an internal 110W power supply. 3512
and 3612 repeaters provide redundant hot-swappable load-sharing power
supply (90W) capability .
Compaq Netelligent Management Software is included free of charge
(2624 and 3612 managing units).

LED Indicators
The repeater has several LED indicators to help you monitor and manage the
repeater. Table 1-1 describes the repeater LEDs.
Model 2524/2624 LEDs
The LEDs on the left side of the front panel indicate the collision status, power
supply, and general status of the repeater. The LEDs above each RJ-45 port
indicate activity on those ports. When you power on a managing 2624 repeater,
it performs a power-on self test (POST). The POST lasts approximately 1
minute. After the POST, all LEDs automatically change to their operational
modes.
Model 3512/3612 LEDs
The LEDs on the left side of the front panel indicate the status of both power
supplies (PWR A/main and PWR B/redundant) and the general repeater status.
The LEDs on the right side of the front panel show the collision status of the
repeater and the current backplane selection (1, 2, or 3). The LEDs above each
RJ-45 port indicates activity on those ports.
When you power on the managing 3612 repeater, it performs a power-on self
test (POST). The POST lasts approximately 1 minute, depending on the amount
of DRAM installed in the repeater (see Appendix C “Upgrading the DRAM”).
After the POST, all LEDs automatically change to their operational modes.

NOTE: LEDs listed as “Yellow” might appear orange on the front panel.
RJ-45 Ports
The repeater’s RJ-45 ports allow connection to UTP or STP cabling to
workstations and servers in a 100Base-T network.
Smart Uplink Slot (2624, 3512/3612 Models)
The Smart Uplink slot houses a Smart Uplink module (SUM), which serves as a
connection point between repeaters, repeater stacks, and other manufacturers'
100Base-T repeaters or stacks. Smart Uplink modules let you extend your
network without the usual repeater hop limitations inherent with Class I
repeaters. Figure 1-4 shows the Smart Uplink modules.
