FAN 1 is OK

FAN 2 is OK

FAN PS-1 is OK

FAN PS-2 is NOT PRESENT


I wanted to see what the html version showed and in this format we have FAN 4 Failure Alerts. Please see attached. Can anyone tell me if there is or should be a FAN 4 to begin with?

Thanks for the ratings.  It doesn't report a "failure", per se.  It just says that it can't detect the fan for the redundant PS.

Fan 4 is should be coming from the redundant Power Supply.  If you don't have a redundant power supply option installed, then please disregard this.


If you do, then contact Cisco TAC and request for an RMA of the faulty component.
