Alarms
The E600i 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 E600i non-functional.
A minor alarm is any fault that threatens the operation of the E600i.
You can monitor alarm conditions on the E600i 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 E600i 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.
