1.16.2 Monitoring Activities and Alarms
This section identifies the types of network and maintenance functions that can be monitored, detected
and corrected by the AirLink 8000 software. The EMS receives unsolicited diagnostic information in
event messages. Some events are interpreted as alarms and sound an audible alert.
Using the Diagnostics window functions, you can:
-- Clear Alarms
-- Request Equipment Status
-- Send Loopback Tests
-- Reboot an RBU
-- View RBU Properties
-- Diagnose Alarms
-- Resolve EMS/RBU Communications Failures
-- Resolve Rack Alarms
-- OVER TEMP
-- AIR MOVER
-- PWR SPPLY
-- RF-PA
-- PRM PWR1
-- PRM PWR2
-- Resolve RBU CCA Failures
-- Interpret Miscellaneous Alarm Events
The AirLink 8000 system software continually monitors the health of the system. If a noteworthy event
occurs, the component that detects the event sends an event message to the EMS. The EMS displays the
event in the Systems Events List in a Diagnostic window.
Events are diagnostic in nature and contain information specific to the condition being reported. The
event includes a severity indicator. 
The EMS system defines the following severity levels:
-- D=>Debug message
-- I=>Informational
-- A=>Audit
-- W=>Warning
-- E=>Error
-- F=>Fatal
An alarm is an event, generated by AirLink 8000 software that has a severity level of Error or Fatal. In
addition to displaying the event, the EMS sounds an audible alarm that consists of a short tone repeated
once every second. This alarm can be cleared from the EMS.
