Avaya 518-456-804 manual Checking the LEDs

2 Installing Your System Quick Reference Guide

•If your system has a 1600 DSL module, initialization of the line and extension ports may take up to 40 seconds. The initialization of the 1600 DSL module itself may take from 2 to 7 minutes

•If your system has a T1 module, initialization may take up to one minute.

Checking the LEDs

After you power up your system, check the green lights on the fronts of the modules:

•If a single light is out, power down the control unit, reseat the module, and then power up the carrier.

•If multiple lights are out, power down the carrier, reseat either both modules (2-slot carrier) or the leftmost module that has a light out (5-slot carrier), and then power up the carrier.

If the lights are still out, see the “Customer Support Document” on the accompanying compact disc for information about whom you should contact.
