Alarms
The E1200 generates major and minor alarms for the following conditions:
• fan trays status
• Power Supply status
• fan tray status
• power supply status
• RPMs status
• high temperature on RPMs
• line cards status
• high temperature on line cards
• SFM3s status
• high temperature on SFM3s.
A major alarm is any fault that would render the E1200 non-functional.
A minor alarm is any fault that threatens the operation of the E1200.
You can monitor alarm conditions on the E1200 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 E1200 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.
