AT-MR420TR and AT-MR820TR Installation Guide

Note

A data packet is too fast for the human eye to distinguish on

an LED, therefore the LEDs will not reﬂect real-time activity.

The repeater artiﬁcially stretches the LED on time for easier

observation.

Figure 6: Port Indicators

Each RJ45 repeater port has two LEDs — LINK OK and Receive:

❑ LINK OK

— No light—Indicates typically a physical connection problem.

The device at the other end of the cable may be powered off,

the cable may be loose or disconnected, or the cable has been

wired incorrectly. Check the crossover cable.

— Green (Steady)—Indicates a valid link exists.

❑ Receive

— Amber (Flashing)—Link is OK, port is not partitioned and

there is activity on the port. Brief flashes indicate low traffic

levels.

In short, port status LEDs show the functionality of the port. If the

LINK OK status light is green and the Receive status is flashing

amber, a signal is being received and the segment attached to the port

is functional.
