Section SNMP Traps and MIBs you would try : CISCO-ENTITY-FRU-CONTROL-MIB, for your task.
In order to get the right information you need to enable the entity traps in the device :
vpn(config)# snmp-server enable traps entity
After that run the snmpwalk for ciscoEntityFRUControlMIB :
C:\usr\bin>snmpwalk -v2c -c cisny 172.16.4.230 1.3.6.1.4.1.9.9.117
SNMPv2-SMI::enterprises.9.9.117.1.3.1.0 = INTEGER: 1
This is a TruthValue you are going to received just 2 values :
1: ok
2: false
If you received (1) it means it is working, however if you don't have the entity traps enable you will received (2) :
vpn(config)# no snmp-server enable traps entity
C:\usr\bin>snmpwalk -v2c -c cisny 172.16.4.230 1.3.6.1.4.1.9.9.117
SNMPv2-SMI::enterprises.9.9.117.1.3.1.0 = INTEGER: 2
This test is for version 8.4(1).
There are some bugs for the same behavior but for ASA 5585:
CSCty32558 SNMP power supply sensor values on ASA 5585 oscillate
It is fixed in 8.4
CSCul90037 ASA5585 Power supply entries needs to be updated in ENTITY-MIB
There is an enhancement request for a trap when the power supply module is removed/installed and Power off/on
CSCtr76874 SNMP trap for Power Supply does not generate
Hope it helps!
