Overview
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.

Introduction
1.3.1 Connectors

attach directly to the network by using unshielded twisted-pair (UTP)
cabling. The ATX power supply provides the power for the module.
NOTE
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.
1.3.2 LEDs
An internal receive/transmit pair crossover is provided in the
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.

The 3H08-04 supports fiber optic and the IEEE 802.3 100BASE-FX
specification.
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.
