Alarms
The E-Series 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 may render the E-Series non-functional.
A minor alarm is any fault that threatens the operation of the E-Series.
You can monitor alarm conditions on the E-Series system through the console, LEDs, and audible alarms.
If you configure the SNMP command (
snmp-server enable traps envmon
), the FTOS also sends an
SNMP trap.
In the E-Series 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.
