Alarms
The E300 System generates major and minor alarms for the following conditions:
• fan tray status
• power supply status
• RPMs status
• high temperature on RPMs
• line cards status
• high temperature on line cards
• SFMs status
• high temperature on SFMs.
A major alarm is any fault that would render the E300 System non-functional.
A minor alarm is any fault that threatens the operation of the E300 System.
You can monitor alarm conditions on the E300 System system through the console, LEDs, and audible
alarms. If you configure the SNMP command (
sends an SNMP trap.
In the E300 System system, alarms are logged for each occurrence, but the system may not send an event
log for multiple occurrences. For example, whenever a module exceeds the shutdown threshold, the
module shuts down.
If more than one module exceeds the warning or high temperature thresholds within a five minute period,
the system generates one event for all effected modules, but alarms are logged for each occurrence. If the
modules temperature falls to 5° lower than the warning threshold temperature, the system clears the alarm
and an SNMP trap.
