Chapter 1
Overview
The Compaq Netelligent 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 the repeaters 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. The series offers a wide array of features for a
versatile, low-cost stackable repeater solution.
The repeaters are available in two models:
Model 3612 — 12-port managed 100Base-TX repeater (Part No.
267007-001)
Model 3512 — 12-port unmanaged 100Base-TX repeater (Part No.
267008-001)
Features
The repeaters provide these features:
12 RJ-45 ports, one Smart Uplink port for a Smart Uplink Module
(SUM), and one console port for Telnet and TFTP support (Model 3612
only)
12 bi-colored LED indicators show port activity, port link, and port
disable/auto partition; other LEDs show collisions, the currently selected
backplane, 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) and lets you
integrate multiple 100 Mb/s repeaters into an existing 100Base-T
configuration without normal repeater hop limitations
Four-group RMON (Remote MONitor) support allows remote
diagnostic monitoring via the network management system
Fast Ethernet wiring standards ensure compatibility with all types of
UTP cabling

LED Indicators
The repeater has several LED indicators to help you monitor and manage the
repeater. 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
the RJ-45 ports indicate activity at those ports.
When you power on a managed repeater (Model 3612), it performs a power-on
self test (POST), which 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 normal modes of
operation.

RJ-45 Ports
The repeater has 12 RJ-45 ports that let you connect UTP or STP cabling to
workstations and servers in a 100Base-T network.
Smart Uplink Port
The Smart Uplink port houses a Smart Uplink Module (SUM), which serves as
a connection point between repeaters, repeater stacks, and other manufacturers'
100Base-T repeaters or stacks. SUMs let you extend your network without the
usual repeater hop limitations inherent with Class I repeaters.

Power Supply
The repeaters are equipped with a single 90-watt power supply module (Part
No. 267322-001). If desired, you can purchase another power supply and
operate the repeater in a redundant power supply configuration. The repeater
has two power supply bays on the back panel. The left bay houses the main
power supply (A). The right bay houses the redundant power supply (B).

Migrating from 10Base-T to
Fast Ethernet
Fast Ethernet (100Base-T) has evolved from standard Ethernet (10Base-T).
Therefore, migrating to Fast Ethernet is fairly simple. Consider the following
three suggestions as you incorporate Fast Ethernet into your network:
Purchase dual-speed Network Interface Cards (NICs) from this point
forward. These NICs operate at 10 Mb/s or 100 Mb/s, so you can use
them with your 10Base-T repeaters now and continue to use them when
you decide to purchase 100Base-T equipment.
Verify that any fiber runs you plan to use at 100 Mb/s meet the distance
limitations discussed in the “Cable Requirements” section in Chapter 2,
“Planning Repeater Installation.”
Purchase 100Base-TX repeaters and reconnect the dual-speed NICs to
these repeaters. Interconnect the 10 Mb/s and 100 Mb/s networks using a
server, dual-speed switch, or a router.
Figure 1-7 shows an example of a network configuration that incorporates both
10Base-T and Fast Ethernet equipment, including the 100Base-TX repeater.

Fast Ethernet Repeater Management
The managed 100Base-T repeater (Model 3612) contains a Management
Daughtercard (MDC100), which provides SNMP management through both in-
band and out-of-band communications. This repeater uses a master/slave
management architecture in conjunction with the repeater hardware to provide
four-group RMON support (Statistics, History, Alarm, and Event) in a stack of
100Base-T repeaters.
In addition to normal repeater operation, all managing repeaters provide in-
band and out-of-band management via a dedicated local MAC port and the
front panel, DB9, COM port:
In-band (or out-of-band via SLIP): SNMP, RMON, Telnet console, and
TFTP download
Out-of-band via VT100 interface: Same console as Telnet and firmware
upgrades
You can perform the following operations via a network management
application, such as the HubView Network Management System:
Select the backplane
Enable or disable ports
Enable port intrusion and security
Monitor port link status, port partition/enable status, and port statistics
NOTE: The repeater retains most configuration settings when powered down and
automatically re-initializes during the power-up cycle.
For more information about the repeater's management capabilities, see Chapter
4, “Repeater Management.”
Internal DIP Switch
If management is not available for the repeater, you can isolate a repeater's
collision domain from the other repeaters in the stack by setting an internal DIP
switch. This switch is accessible through the Power Supply A or B opening.

1-10 Overview
Writer: Chris Seiter Project: Chapter 1 Comments: 185811-002
File Name:Fast_1.doc Last Saved On:7/10/96 9:46 AM
See Appendix B, “Internal DIP Switch” for information about switch settings.
CAUTION: Remove power from the repeater before you set the DIP
switch.
NOTE: Use the DIP switch only when all other configuration methods are
unsuccessful.
100Base-T Repeater Expansion
Each 100Base-T repeater has an expansion interface that consists of two 100-
pin connectors (UP and DOWN) on the repeater's back panel. You can achieve
both management and Ethernet expansion by connecting the UP connector of a
lower repeater to the DOWN connector of an upper repeater using a FlexPlane
connector (Part No. 810172-000).

The FlexPlane includes a management bus that enables one managed repeater
to manage all other unmanaged 100Base-T repeaters in a stack. All internal
stack management is out-of-band so that there is no impact on your network
traffic.
