LED Indicators
Refer to the Maintenance for Avaya DEFINITY® Server SI (555-233-123) documentation for detailed
alarm and LED descriptions. If a maintenance object begins to fail some periodic tests, the system
generates an alarm. The system identifies 3 levels of alarms:
•
Major Alarms
attention.
•
Minor Alarms
portion of the system to be inoperable. This condition requires action, but its consequences are not
immediate. Problems might be impaired service to a few trunks or stations or interfering with one
feature across the entire system.
•
Warning Alarms
equipment external to the system. Warning alarms are not reported to the attendant console or
INADS.
Alarms are communicated to the system users and technicians by entries in the alarm log and the lighting
of LEDs located on the attendant console, on all circuit packs, and, optionally, on customer-designated
voice terminals.

Attendant Console LEDs
The console has 2 red LEDs, labeled "ALM" and "ACK". The ALM LED lights steadily when there is a
major or minor alarm at the system cabinet. The ACK LED lights steadily if the alarm has been
successfully reported to INADS. If the system is unable to report the alarm to INADS, the LED flashes;
this signals the attendant to call INADS and report the alarm.
Terminal Alarm Notification
Terminal Alarm Notification is an optional feature that displays several types of alarms on voice
terminals with administered feature buttons or the attendant console. A maximum of 10 digital and/or
hybrid voice terminals may be used.
When an alarm occurs, the green status LED associated with the assigned button is in a steady state. The
LED may be turned off by pressing the button associated with the LED. If the LED is off and the alarm
has not been resolved by the time maintenance reschedules testing, the green status LED resumes its
steady state.
