Introduction
The 9T122-08 MicroLAN™ Switch Extension Module, shown in Figure 1-1, is a
three port Token Ring switch module. This module supports two separate Token
Rings with four lobe connections each, and an interface to the FNB backplane.
Each front panel Token Ring also supports Ring-in/Ring-out connections by
using plug-in Token Ring Port Interface modules (TPIMs).
Features
Processor
The 9T122-08 is equipped with an advanced Intel i960 microprocessor. This
microprocessor provides a platform for all management functions within a
scalable RISC-based architecture.
System Management
Interfaces to the two System Management Buses (SMB-1 and SMB-10) for
intermodule management.
Connectivity
The 9T122-08 provides four RJ-45 Trunk Coupling Unit (TCU) lobe connectors for
each of the two front panel Token Rings. Each front panel Token Ring has sockets
for TPIMs, allowing for Ring-in/Ring-out connections
SRT Packet Switching
SRT Bridging between the front panel Token Ring connections and SR-TB
bridging to any other module in the chassis via FNB -1 or FNB -2 of the FNB bus.
The module is capable of Transparent Bridging and/or Source Route Bridging.
IEEE 802.1d Spanning Tree Protocol is supported in all bridging functions.
Translational bridging between Source Routing and Transparent Frames types is
also performed for packets destined for the FNB.

Introduction
1-2
Management Information Base (MIB) Support
The 9T122-08 module provides MIB support including:
• IETF MIB II (RFC 1213)
• IETF Bridge MIBs (RFC 1493 and 1525)
• IEEE 802.5 Token Ring MIB (RFC 1231)
• Cabletron Enterprise MIBs
Ring Security
Ring Security prevents unauthorized stations from attaching to the ring. Using
Local or Remote Management, the module may be configured as to which MAC
addresses are allowed to operate on the ring.
Telnet
A telnet session can be set up with the module to provide access to the Local
Management screens.
LANVIEW LEDs
The 9T122-08 uses LANVIEW – the Cabletron Systems built-in visual diagnostic
and status monitoring system. With LANVIEW LEDs, you can quickly identify
the device, port, and physical layer status at a glance.
Hot Swapping
The 9T122-08 can be installed or removed from the chassis while the SmartSwitch
9000 is powered up without affecting the operation of the remaining modules in
the chassis.
For a complete list of supported MIBs, refer to the release notes provided in the
module package.

Installing the SmartSwitch 9000
Module
This module uses TPIMs for the front panel RI/RO connections. They are not
shipped with the module and must be purchased separately. There are
configuration switches on some of the TPIMs. They are described in the
instruction card shipped with the TPIMs. For information on the various TPIMs
models, see Appendix A .
Unpacking the Module
1. Carefully remove the module from the shipping box. (Save the box and
packing materials in the event the module must be reshipped.)
2. Remove the module from the plastic bag. Observe all precautions to prevent
damage from Electrostatic Discharge (ESD).
3. Carefully examine the module, checking for damage. If any damage exists,
DO NOT install the module. Contact Cabletron Systems Technical Support
immediately.
Installing anTPIM
The 9T122-08 MicroLAN module is shipped without TPIMs. To install a TPIM,
follow the procedure below:
1. Loosen the mounting screw and remove the faceplate from the RI/RO port on
the 9T122-08 or
If replacing a TPIM, loosen the mounting screw and pull the TPIM straight out from
the 9T122-08.
2. Slide the new TPIM into place as shown in Figure 2-1.

3. Ensure proper mating between the connectors on the rear of the module and
on the inside of the 9T122-08.
4. Tighten the mounting screw.

Ring Speed
The module defaults to a 16Mbps ring speed on all rings. This may be changed
though local management.
Installing the Module into the SmartSwitch 9000
Chassis
The SmartSwitch 9000 MicroLAN Module may be installed into any of the 14 slots
that are available. To install a module, follow the steps below:
1. Switch off the power supplies and remove all power from the SmartSwitch
9000 chassis.
2. Remove the blank panels, covering the slots that the module is being mounted
in. All other slots must be covered, if modules are not being installed, to
ensure proper airflow and cooling.
3. Attach one end of the ESD wrist strap packaged with the SmartSwitch 9000
chassis to your wrist. Plug the other end into the ESD Wrist Strap Grounding
receptacle in the lower right corner of the SmartSwitch 9000 chassis shown in
Figure 2-4.
4. The module is installed into the chassis by sliding it into slots and locking
down both the top and bottom plastic tabs, as shown in Figure 2-4. Take care
that the module slides in straight and engages the backplane connectors
properly. When installing the module, ensure that both circuit cards are
between the card guides, as shown in Figure 2-4. Check both the upper and
lower tracks of both cards.

The Reset Switch
The Reset switch is located on the front panel, under the top plastic tab, as shown
in Figure 2-5. It serves two functions:
• Pressing the reset switch twice within three seconds causes the processor (i960)
to reset.
• Pressing and holding the switch on for three or more seconds causes the
module to shutdown. Pressing and holding again for three seconds restarts the
module.
SNMP management may be used to disable this switch to enhance module
security.
