There are different traps for fan status depending on which Cisco device you
are interested in.  Here are some we use for Cisco routers, LS1010s and
Catalyst 5000s:

Enterprise Name (Enterprise ID)                 Event Name (event number)
cisco-envmon (1.3.6.1.4.1.9.9.13.3)             ciscoEnvMonFanNotification
(specific 4)
ciscoLS1010ChassisMIB (1.3.6.1.4.1.9.5.11.2)
ciscoLS1010ChassisFailureNotification (specific 1)
cisco-dcd (1.3.6.1.4.1.9.5)                     chassisAlarmOn (specific 5)
