There is no specific object for the PS fan in this version of IOS. However, it does support the ciscoEnvMonSupplyStatusTable. The ciscoEnvMonSupplyState object will give you the overall status of the power supply.

What type of device is this, and what version of code is it running?

Got this object, caemSupplyFailedComponent, from CISCO-ACCESS-ENVMON-MIB, but i'm not getting the response from an snmpwalk that I expect. Still doesn't indicate the failure of the fan on the PS.
