Nortel Networks Media Dependent Adapter - Manual (Page 3)

Introduction
This document provides procedures for installing optional
plug-in media dependent adapter (MDAs) into supported
Bay Networks products equipped with an expansion slot.
The MDAs can support high-speed connections to servers,
shared Fast Ethernet hubs, or backbone devices.
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)
Note: Installing or removing an MDA from an
operating switch (hot-swapping) 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.
