Avaya 03-300430 User Manual

The console has two red LEDs, labeled “ALM” and “ACK.” The ALM LED lights steadily when 
there is a major or minor alarm at the switch cabinet. The ACK LED lights steadily if the alarm 
has been successfully reported. If the system is unable to report the alarm, the LED flashes; this 
signals the attendant to call the Avaya alarm receiving system and report the alarm.

Typically each circuit pack has three LEDs on the front panel visible at the front of the carrier. 
There are some exceptions to this (for example, DS1CONV or IPSI circuit pack) that are 
covered later in this section. On most circuit packs, the LEDs indicate the following when lit 
(

on page 257). Exceptions to these indications are explained in 

subsequent sections.

This section includes LED interpretation on the following circuit packs:

Red

Alarm

The system detected a fault in this circuit pack. The alarm log should contain 

an on-board alarm for this circuit pack or one of the maintenance objects 

associated with it. The red LED is also lit briefly when a circuit pack is 

inserted or reset. If the circuit pack passes its initialization tests, the LED is 

extinguished. If a fault is detected, it remains lit.

Green

Testing The system is currently running tests on this circuit pack as part of 

background maintenance or demand testing. This LED is also lit briefly 

during initialization tests when a circuit pack is inserted or reset.

Yellow

Busy

The circuit pack is currently in use by the system.
