Product Description

Overview

Allied Telesyn’s multiport AT-MR420T/AT-MR820T Micro Repeaters

are a compact, inexpensive solution for all Ethernet media conversions

and Local Area Network (LAN) applications.

The AT-MR420T/AT-MR820T Micro Repeaters combine 10 Mbps

Ethernet connectivity with the same features and functionality of

larger, more expensive repeaters. At the same time, it supports full-

length cable segments with the maximum number of supported devices

allowed within IEEE 802.3 standards.

AT-MR420T/AT-MR820T Faceplates

Figure 1 and Figure 2 show the front and back panels of the two

versions, respectively. The front panel consists of eight Network Load

LEDs indicating the percentage of network utilization, and eight/

sixteen Link and Receive status LEDs for each network port. Three

additional LEDs indicate Activity, Collision, and Power for the

repeater itself.

The back panel consists of four/eight Unshielded Twisted Pair (UTP)

RJ45 network ports (including port 4/8, an uplink port), and the AUI

(10Base5) backbone network port. The three-pin AC power receptacle

is located on the far right end of the back panel.
