Federal Communications Commission (FCC) Compliance Notice: Radio Frequency Notice

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 generates, uses, and can radiate radio frequency energy. If it is not installed and used in accordance with the instruction manual, it may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to take whatever measures may be necessary to correct the interference at their own expense.

EN 55 022 Declaration of Conformance

This is to certify that the Bay Networks 100BASE-FX/TX MDA are shielded against the generation of radio interference in accordance with the application of Council Directive 89/336/EEC, Article 4a. Conformity is declared by the application of EN 55 022 Class A (CISPR 22).

Warning: This device is a Class A product. In a domestic environment, this product may cause radio interference, in which case, the user may be required to take appropriate measures.

These products conform to the provisions of Council Directive 89/336/EEC and 72/ 23/EEC. The Declaration of Conformity is available on the Bay Networks World Wide Web site at www.baynetworks.com.

Introduction

This document provides proced ures for i nst alli n g opt ion al plug-in media dependent adapter (MDAs) into supported Bay Networks products equipped with an expansion slot. The MDAs can sup port high -speed connections to serv ers, shared Fast Ethernet hubs, or backbone devices.

Installing or removing an MDA from an

Note:

operating switch (hot-swappin g) causes the switch to auto-reset as soon as the insertion or removal of the device is sensed by the switch software. Although the switch is hot-swap survivable, data integrity during the reset will be compromised.

The following MDA versions are available:

• 400-4TX MDA --- 10BASE-T/100BASE-TX MDA (4-port copper)

• 400-2FX MDA ---100BASE-FX MDA (2-port fiber)

• 450-1SR MDA --- 1000BASE-SX MDA (1-port shortwave gigabit fiber, with 1-redundant port)

• 450-1SX MDA --- 1000BASE-SX MDA (1-port shortwave gigabit fiber)

• 450-1LR MDA --- 1000BASE-LX MDA (1-port longwave gigabit fiber, with 1-redundant port)

• 450-1LX MDA --- 1000BASE-LX MDA (1-port longwave gigabit fiber)

Bay Networks is constantly adding new models and features to existin g product lines; see your Bay Networks sales representative for a full range of available MDAs.

400-4TX MDA

The 400-4TX MDA (Figure 1

) uses a standard RJ-45 connector to attach an Ethernet device. This MDA is capable of operating at either 10 Mb/s or 100 Mb/s speed. The speed is determined through autonegotiation with its connecting device.
