FCC Notice
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial environment.
This equipment uses, generates, and can radiate radio frequency energy and if not installed in
accordance with the operator’s manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause interference in which case the user
will be required to correct the interference at his own expense.
WARNING: Changes or modifications made to this device which are not expressly approved by the
party responsible for compliance could void the user’s authority to operate the equipment.
VCCI Notice
This equipment is in the 1st Class Category (information equipment to be used in commercial and/or
industrial areas) and conforms to the standards set by the Voluntary Control Council for Interference
by Information Technology Equipment (VCCI) aimed at preventing radio interference in commercial
and/or industrial areas.
Consequently, when used in a residential area or in an adjacent area thereto, radio interference may be
caused to radios and TV receivers, etc.
Read the instructions for correct handling.

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.
