3.4 Using Logged Operation Events
(See “Event Log Menu” on Page 71)
The transceiver’s microprocessor monitors many operational parameters and logs them as various classes
of “events”. If the event is one that affects performance, it is an “alarm”. There are also normal or routine
events such as those marking the rebooting of the system, implementation of parameter changes and
external access to the Management System. Informational events are stored in temporary (RAM) memory
that will be lost in the absence of primary power, and Alarms will be stored in permanent memory (Flash
memory) until cleared by user request. Table 3-4 summarizes these classifications.
These various events are stored in the transceiver’s “Event Log” and can be a valuable aid in troubleshooting
unit problems or detecting attempts at breaching network security.
3.5 Alarm/Event Conditions
(See “View Current Alarms” on Page 73)
Most events, classified as “critical” or Alarms will make the PWR LED blink, and will inhibit normal oper-
ation of the transceiver. The LED blinks until the corrective action is completed.

Level Description/Impact Storage
Informational Normal operating activities RAM
Minor Does not affect unit operation RAM
Major Degraded unit performance but
still capable of operation RAM
Critical Prevents the unit from operating Flash
