Overview
FE Switch Module User Guide Page 1-3
1.2 OVERVIEW
Cabletron Systems Fast Ethernet Switch Modules connect the ATX hub
to a maximum of four individual Ethernet IEEE 802.3 Local Area
Networks (LANs). Through the ATX backplane, connectivity to other
Fast Ethernet devices, as well as connectivity to FDDI, Token Ring, and
Ethernet networks is supported. You can configure the module to support
Transparent Spanning Tree, Source Routing, or Source Routing
Transparent Bridging on each of the FDDI, Token Ring, or Ethernet ports
of the ATX. The ATX is also able to translate higher level protocols to
allow communications between end-nodes on Ethernet and end-nodes on
FDDI or Token Ring; protocols translated include TCP/IP, Novel
NetWare, and AppleTalk Phase II.
The switch modules include processing circuitry for receiving and
forwarding data packets between the connected devices. Each module
contains an offline button as well as several light emitting diodes (LEDs)
that indicate the operational status of the module and the individual ports.
You can install the switch modules in any of the five interface slots of the
ATX. Each switch module provides connectivity to four distinct 100 Mb
LANs.
1.3 3H02-04 FE SWITCH MODULE
The 3H02-04 (Figure 1-2) provides connection for four independent
100BASE-TX LANs to the ATX backplane and packet processing engine
(PPE). It includes processing circuitry for receiving and forwarding
packets between the connected 100BASE-TX LANs within each module.
The 3H02-04 contains several LEDs to indicate the module’s operational
status. Each segment has link test enabled and supports receive pair
polarity reversal detection and automatic correction.
The 3H02-04 supports unshielded twisted pair (UTP) and IEEE 802.3
100BASE-TX specification.
Chapter 1:
Introduction
Page 1-4 FE Switch Module User Guide
1.3.1 Connectors
The 3H02-04 includes four 8-pin RJ45 receptacle connectors that you can
attach directly to the network by using unshielded twisted-pair (UTP)
cabling. The ATX power supply provides the power for the module.
1.3.2 LEDs
The 3H02-04 contains a total of 14 green LEDs labeled LINK, RX, and
TX for each segment, plus PROC and PWR for the module. The LEDs are
described in Chapter 5 of this manual.
1.3.3 Offline Button
Use the offline button before swapping the module, to take it offline until
the replacement is installed.
Figure 1-2 3H02-04 Front Panel
NOTE
An internal receive/transmit pair crossover is provided in the
second connector on each port. This means that when either a
station or server is directly attached to a 3H02-04 port, you can
choose to use either straight-through or crossover cabling. For
more cabling and crossover information, see Appendix B.

1.4.1 Connectors
The 3H08-04 includes four pairs of fiber optic socket connectors for fiber
optic cabling. Receive (RX) and transmit (TX) connectors are clearly
marked on the front panel of the module. The ATX power supply
provides the power for the module.
1.4.2 LEDs
The 3H08-04 contains a total of 14 green LEDs labeled LINK, RX, and

CHAPTER 2
CONNECTING TO THE NETWORK
This chapter provides reference material and instructions that network
administrators can use to configure the Fast Ethernet Switch Modules.
For instructions on adding a switch module to the ATX, see Chapter 5,
Adding/Swapping Modules
.
2.1 POWER-UP LED SEQUENCE
Watch the LED sequence during power-up. It takes about 1 minute for the
ATX to complete the power-up diagnostics. The ATX begins system
diagnostics on the PPE (topmost module) and then individually on each
installed module, starting at the top and working down to the bottom.
Using both processors, the specific power-up tests run on the switch
module are:
ROM checksum test
Instruction memory test
Memory map tests
Interrupt tests
Fast Ethernet data loopback tests
The power-up LED sequence for the Fast Ethernet module is as follows:
1. All LEDs flash.
2. The PWR LED remains on, and the TX LEDs flash.
3. On each switch module, the following occurs:
a. The PROC LED comes on for 5 seconds, blinks, then remains lit.
b. The RX and TX LEDs flash momentarily.
Chapter 2:
Connecting to the Network
Page 2-2 FE Switch Module User Guide
4. After a few seconds, the switch module reboots and the PROC LED
comes on.
5. All other LED activity beyond this point is a function of the
configuration and connection of the ATX.
2.2 CONNECTING TO A NETWORK
To connect the switch module to a Fast Ethernet network, use the
following types of Ethernet cable:
Unshielded Twisted Pair (UTP for 100BASE-TX)
Fiber (100BASE -FX)
2.2.1 Connecting the 3H02-04 FE Switch Module
You can connect each of the four 100BASE-TX ports of the 3H02-04 to a
100BASE-TX port on a device such as a workstation, server, hub, etc.,
using unshielded twisted pair cable. Each segment on the 3H02-04
provides two connectors. Depending on whether crossover is provided on
the device being connected to, use either crossover or straight-through
UTP cable to connect to a port. Keep in mind, however,
to use only
one
connector on each segment
. For more information on cable
specifications, see Appendix B.
Connect one end of a UTP cable to an open port on the 3H02-04 and the
other end to the RJ45 port on the device (see Figure 2-1).

2.2.2 Connecting the 3H08-04 FE Switch Module
You can connect each of the four pairs of ST fiber ports on the 3H08-04 to
a 100BASE-FX port on a device such as a hub, using fiber optic cable.
Each fiber segment has a pair of female ST connectors clearly marked as
“RX” and “TX.
Attach the transmit (TX) connector on the 3H08-04 to the receive (RX)
connector on the attached device. Similarly, you must then connect the
receive (RX) connector on the 3H08-04 to the transmit (TX) connector on
the attached device (see Figure 2-2). For more information on cable
specifications, see Appendix B.
