Installing and Maintaining the E1200i System
87
The E1200i generates major and minor alarms for the following conditions:
•
fan trays 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 E1200i non-functional.
A minor alarm is any fault that threatens the operation of the E1200i.
You can monitor alarm conditions on the E1200i 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 E1200i 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.
