Introduction
The 9T125-08 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 9T125-08 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 9T125-08 provides four RJ45 Trunk Coupling Unit (TCU) lobe connector 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 may occur 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
Management Information Base (MIB) Support
The 9T125-08 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
• RMON
Ring Security
This feature 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.
LANVIEW LEDs
The 9T125-08 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 9T125-08 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.
Webview
Management of the 9T125-08 may be accomplished using Cabletron’s WEBVIEW. This
allows managing the module though an on-line browser.

Chapter 2
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 aTPIM
The 9T125-08 MicroLAN extension module is shipped without TPIMs. To install a
TPIM, follow the procedure below:
1. Remove the faceplate from the RI/RO port on the 9T125-08 or, if replacing a
TPIM, loosen the mounting screw and pull the TPIM straight out from the
9T125-08.
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 9T125-08.
4. Tighten the mounting screw.

User Accessible Components
Figure 2-2 shows the various components that are accessible to the user. These
consist of an eight position dip switch (explained in the next section), replaceable
PROMs and sockets for RAM. These will be used for future upgrades.

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, 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 2-3.
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 2-3. Take care
that the module slides in straight and engages the backplane connectors
properly. Ensure that both circuit cards are between the card guides. 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 2-4. 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 the switch again for three seconds
restarts the module.
SNMP management may be used to disable this switch to enhance module
security.
