Monitoring Fan Tray Status
The CMM constantly monitors fan operation. If any of the switch’s fans unexpectedly shuts down, the
CMM sends out a trap and the FAN LED on the CMM’s front panel displays amber.
Note.
To check the switch’s current fan tray status, use the
show fan
command. For example:
-> show fan
Fan Status
------+---------------
Fan-1 Running
Fan-2 Running
For more information about this command, see the “Chassis Management and Monitoring Commands”
chapter in the
OmniSwitch
CLI Reference Guide
.
Fan Tray Redundancy
In the event that one fan tray quits unexpectedly, the remaining fan tray will continue running; switch
operations are not disrupted.
Note.
Fan failure needs to be reported immediately in order to make an RMA unit available, and upon
receiving the unit, it must be replaced immediately. For information on emergency replacement of the fan
tray, refer to
“Removing Fan Trays”
above.
Storing Backup Fan Trays.
It is a good idea to keep at least one backup fan tray in your data facility.
