Minor threshold—When a minor threshold is exceeded, a minor alarm occurs and the following
action is taken for all four sensors:
System messages are displayed.
–
Call Home alerts are sent (if configured).
–
SNMP notifications are sent (if configured).
–
Major threshold—When a major threshold is exceeded, a major alarm occurs and the following
action is taken.
For sensors 1, 3, and 4 (outlet and onboard sensors):
–
System messages are displayed.
Call Home alerts are sent (if configured).
SNMP notifications are sent (if configured).
For sensor 2 (intake sensor):
–
If the threshold is exceeded in a switching module, only that module is shut down.
If the threshold is exceeded in an active supervisor module with HA-standby or standby present,
only that supervisor module is shut down and the standby supervisor module takes over.
If you do not have a standby supervisor module in your switch, you have an interval of 2 minutes
to decrease the temperature. During this interval the software monitors the temperature every
five (5) seconds and continuously sends system messages as configured.
To realize the benefits of these built-in, automatic sensors on any switch in the Cisco MDS 9500
Series, we highly recommend that you install dual supervisor modules. If you are using a Cisco
MDS 9000 Family switch without dual supervisor modules, we recommend that you
immediately replace the fan module if even one fan is not working.
