Introduction
1.4 GENERAL DESCRIPTION
Cabletron Systems 3T01-04 and 3T01-02 modules connect the ATX to a 4
or 16 Mbps Token Ring network. The modules enable connectivity to
FDDI, Ethernet, and Token Ring Networks, and can be configured to
support Transparent Spanning Tree, Source Route, or Source Routing
Transparent Bridging. The ATX is also able to translate higher level
protocols to allow communication between end-user devices on Token
Ring and end-user devices on FDDI or Ethernet. Protocols translated
include: TCP/IP, Novell NetWare, and AppleTalk Phase II.
The Token Ring module ports can be connected to one Token Ring
network. The module contains connectors for shielded twisted pair (STP)
and unshielded twisted pair (UTP) cabling. Each module has eighteen
LEDs which indicate the current status of the module and the Token Ring
networks. The offline button allows you to remove the module for
swapping.
Up to four Token Ring networks can be attached to either module. The
module is available in two models: STP (3T01-04) and UTP (3T01-02).
Each module contains four connectors (STP or UTP), 18 status LEDs,
and an offline button.
The Token Ring module may be installed in any of the fiv e interf ace slots
and the ATX can simultaneously support up to five Token Ring modules.
If five of either the 3T01-04 or 3T02-04 modules are installed, up to 20
networks can be connected.

1.5 STANDARDS
The physical and electrical characteristics of the Token Ring module
conform to the IEEE 802.5 standard. The protocol for the MAC layer is
specified by the IEEE 802.5 standard while that for the Logical Link
Layer is specified by the IEEE 802.2.
1.6 CONNECTORS
The Token Ring modules are available in versions for either UTP or STP
lobe cabling. The STP version of the four port Token Ring module has
four DB9 connectors; the UTP version has four RJ45 connectors. Power
for the module is provided by the ATX backplane.

Introduction
1.7 LEDs
Each Token Ring module provides 18 green LEDs for troubleshooting
and status monitoring. For each of the four Ring ports there are four LEDs
labeled RX, TX, ST, and 16. Additionally there are two module LEDs
labeled PROC and PWR. The LEDs are described in Chapter 5 of this
manual.
Page 1-6 Token Ring Switch Module User Guide
CHAPTER 2
CONNECTING TO THE NETWORK
2.1 INTRODUCTION
Installation of a T ok en Ring network typically requires more planning and
explicit configuration than does a transparently-bridged Ethernet network.
This chapter provides reference material and instructions that network
administrators can use to configure the Token Ring modules.
For instructions on adding a Token Ring module to the ATX, see
Chapter 6,
Adding/Swapping Modules
2.2 POWER-UP LED SEQUENCE
Power up the ATX and observe the LED sequence. 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 progressing from top to bottom.
The power-up LED sequence for the Token Ring module not attached to a
network is as follows:
.
1. All LEDs flash.
2. The POWER and 16 LEDs remain on.
3. After a few seconds the PROC LED comes on.
4. The ST LEDs come on.
5. The RX and TX LEDs flash briefly.
6. The ST and PROC LEDs go off.
7. The PROC LED comes on and the 16 LEDs go off.
8. The TX and RX LEDs flash briefly.
9. The Token Ring module then boots with the PROC and PWR LEDs
on.
10. All other LED activity beyond this point is a function of the
configuration and connection of the ATX.
Token Ring Switch Module User Guide Page 2-1
Chapter 2:
Connecting to the Network
2.3 TYPICAL CONFIGURATIONS
Physical connectivity to a Token Ring network is provided by either
shielded twisted pair (STP) or unshielded twisted pair (UTP) cabling that
connects the Token Ring module to a Hub. Each Token Ring switch
module provides only one kind of connector, either four DB9 connectors
for STP cabling or four RJ45 connectors for UTP cabling.
2.4 CONNECTING THE TOKEN RING MODULE
TO A HUB
It is not possible to attach workstations directly to the ATX Token Ring
port. Either an active or a passive Hub must be used. A passive Hub
contains fairly simple electronics (principally relays) which form a
self-healing electrical ring. An active Hub contains more sophisticated
ring-maintenance circuitry and may be manageable.
2.4.1 Unshielded T wisted Pair
When using Unshielded Twisted Pair cabling in a Token Ring
environment, make sure that it conforms to the specifications in Table 2-1
(this assumes patch cables that are no longer than 8 feet or 2.4 meters):
