•ALARM HISTORY Indicator—present only until it is clicked
away, indicates, in effect, whether someone has noticed the alarm and
looked into its significance. The color of this indicator will be that of
the worst alarm existing for the identified network element (if any
major alarm exists, the color will be red).
NOTE: These two types of indicators operate independently from one another. If
the condition causing the alarm is cleared, resulting in a “green” status indicator,
the history indicator will still remain until it is clicked away. By the same token,
acknowledging the alarm has no effect on the alarm status indicator since that has
no effect on the underlying physical condition causing the alarm.
To view and acknowledge alarms
1. Select ViewÞAlarmOverview to display the AlarmOverview window.
2. Look for ALARM STATUS indicators with colors yellow or red, as shown in
Figure 27.
Figure 27. Units With Alarms
3. Interpret the ALARM STATUS indicators as follows:
•Red = one or more major alarms exist. A major alarm places the
identified unit in standby operating mode (stopping RF functions).
•Ye l lo w = one or more minor alarms exist at the network element. A minor
alarm allows the unit to continue functioning in normal mode.
•Green = no alarms exist at the network element.
4. Check if any unit has an ALARM HIST indicator, such as shown in
Figure 28. If any does, click on the ALARM HIST button (labeled Hist Ack)
to start the process to acknowledge the alarm.

appear from the display, as shown in Figure 30.
6. Check the EMS log file, as shown in Figure 31, for alarm history text to deter-
mine the events associated with the alarm. For information on how to view the
file, refer to Topic 3.15, Viewing the EMS Log File, on page 53.
