Alarms
The C300 System generates alarms for the following conditions:
• fan tray status
• supply status
• RPMs status
• high temperature on RPMs
• line cards status
• high temperature on line cards
A major alarm is any fault that would render the C300 System non-functional.
A minor alarm is any fault that threatens the operation of the C300 System.
You can monitor alarm conditions on the C300 System system through the console and LEDs. If you
configure the SNMP command (
snmp-server enable traps envmon), the FTOS also sends an SNMP
trap.
In the C300 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.
