Chapter 3 Operations
Alarms & Events
show alarm-config
queries the above settings for all of the conditions. See the
CLI command, show alarm-config , on page 111 for more information. These
conditions become manifest in the TimeProvider 500 in three areas:
1. An event log provides history of “entry into” and “exit from” any condition that has
not been configured as disabled. Each entry in the log is timestamped. See show
log , on page 117 for more information.
2. The
show alarm
query provides a listing of all conditions that are currently
present, excluding those that have either been disabled (by user) or set to
severity level = EVENT.
3. The ALARM LED indicates the highest severity level of all conditions that are
currently present. As with
show alarm
, the ALARM LED will not respond to
conditions that have been disabled (by user). Table 3-3 shows the relationship
between highest active severity level and ALARM LED indication.
When an alarm clears, the alarm condition is no longer present and the following
occurs:

An entry is placed into the alarm log showing that the alarm condition has
cleared.

If the alarm information is included in the show alarm response, it will be removed
from that response.

The Alarm LED logic executes and may drive a change in the Alarm LED
indication.
For more information, refer to Alarm System Messages , on page 126 for alarm
message details.
