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).

Chapter 1

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

NOTE

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

For a complete list of supported MIBs, refer to the release notes provided in the module package.

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.
