Alarm LEDs
Table 2-3 describes the BSR 64000 Alarm LEDs on the SRM. The SRM provides
a set of three Alarm LEDs. These LEDs are visible on the module front panel of
the SRM and are labeled: MIN (Minor), MAJ (Major), and CRIT (Critical).

State Interpretation
MIN Yellow Off Off Minor alarms indicate problems that do not have a
serious effect on service to customers or problems
in circuits that are not essential to network element
operation.
MAJ Off Red Off Major alarms are used for hardware or software
conditions that indicate a serious disruption of
service or the malfunctioning or failure of important
circuits. These conditions require immediate
attention and response to restore or maintain
system capability. The urgency is less than in
critical situations because of a lesser immediate or
impending effect on service or system
performance.
CRIT Off Off Red Critical alarms are used to indicate that a severe
service-affecting condition has occurred and that
immediate corrective action is imperative.
Note: When an audible alarm condition sounds, press the ACO button
located on the front panel of the System Resource Module (SRM) to clear
the audible alarm.
