SSIM-T5-04 Token Ring

SmartStack Interface Module

Introduction

The SmartStack SSIM-T5-04 provides four additional Token
Ring ports for the base SmartStack STS16-20RM or STS16­20FRM Token Ring switc h. These ports can be configured just
like the 20 fi xed To ken Rin g port s on t he base s witch. Eac h or
all of the interface module ports can be configured (in
combination with an y of the fixe d port s on the bas e swit ch) to
be used in CrossLink connections, and configured to be
included in virtual LANs. The interface module ports support
address filters and BOOTP/TFTP, Telnet or SNMP sessions.

Figure 1. SSIM-T5-04 interface module Front Panel

The ports on the SSIM-T5-04 i nterface module support Toke n
Ring twisted-pa ir (UTP/STP) media via RJ-45 connectors.
The interface module ports can be confi gured j ust like th e base
switch ports to provide either shared (half-duplex) 4 or 16
Mbps Token Ring connections or dedicated (full-duplex) 32
Mbps connections.

In addition to the RJ-45 Token-Ring connectors, there are 10
LEDs on the faceplate of the in terface module (a set of two for
each port plus two for the interface module general status).
These LEDs indicate th e ope rational status of the interface
module and of the ports.

Installation

1. Power off the base switch by unplugging it.

2. Remove the plate covering the expansion slot on the front
of the base swit ch by unscrewing the two retaining
thum b scr ew s. Keep the plat e f or use in the event th at the
interface modul e is removed.

3. Carefully insert the interface module into the rails on each
side of the expansion slot, sliding it back until the
connector on the interface module is seated into the
conne c t o r at th e ba ck of th e slot.Wh e n th e in t er f ac e
module is fully seated, the interface module faceplate will
be flush with the front of the base switch.

4. Secure the interf ac e m odule with the two attached
thumbscrews.

Testing the interface module

1. Power on the base switch to start diagnostics. The STS16­20RM Token Ring switch indicates that dia gnostics are in
progress by turning on its DIAG LED. After about a
minute, the interface module DIAG LED will also be
turned on.

2. Verify that the base switch diagnostics have been
completed su ccessfully. On the STS16-20RM, this is
indicated wh e n it s D IAG LE D is tu r ned off, and th e E R R
LED stays turned off. Diagnostics can take up to four
minutes to complete.

3. Verify that the ERR LED on the interface module is off. If
it is of f, dia gnostics h av e been succ essfully complete d, and
the interfac e module is ready for configuration.

Configuration

The interface module ports can be configured j ust lik e the base
switch ports . They will appear as additional por ts on any
configuration panel where ports are listed. The port numbers
will begin where the numb ers of the base switch stop.

If for example the base switch has 20 ports and an interface
module in the left front panel slot, the interface module ports
will appear after P ort 20 on the various port configuration
panels and be desi gnated 21, 22, 23 and 24. If t he modu le is in
the right front panel slot, the ports will be desi gnated 25, 26,
27 and 28.

Follow the instructions contained in the

20RM/STS16-20FRM Token Ring Switches, Installation and
User Guide

for configuring the interface module ports.

Troubleshooting

•

If you are ins talling the inte rface modul e and the LEDs do
not come on when the base switch is powered on, verify
that the interface module is properly seate d in the slot.

•

During diagnostics, the interface module DIAG LED is
on. If the ERR LED is on at any time , it indicates that the
interface module is defective and needs to be serviced.

The individual inte rface modul e port s are like the base swit ch
ports for the purpo ses of troubleshooting. See the

STS16-20RM/STS16-20FRM Token Ring Switch, Installation
and User Guide

for troubleshooting hints.
