LED Indicators

This document describes units manufactured after 13 January 2005. See the prior version of this document for information about units manufactured on or before that date.

Whenever both ENE2020 E1 connections have lost link or have presented an E1 Alarm, the Ethernet link will automatically be disabled (as indicated by no illumination of the Ethernet 100, Act and Lnk LEDs). Upon reestablishment of at least one of the E1 connections, the Ethernet link will be reinstated and the Ethernet LEDs will reflect current Ethernet Status.
