We have a Cisco 7609 and I need to monitor the power supplies via SNMP. The appropriate OID for each power supply is as follows:

Power Supply 1 Status: .1.3.6.1.4.1.9.5.1.2.4.0

Power Supply 2 Status: .1.3.6.1.4.1.9.5.1.2.7.0

The appropriate MIB is CISCO-STACK-MIB, looking at the chassisPs2Status section. A return value of 2 means OK, anything else is an error.

The OIDs for the status of the fan trays are:

Fan Tray 1: .1.3.6.1.4.1.9.9.13.1.4.1.3.3
Fan Tray 2: .1.3.6.1.4.1.9.9.13.1.4.1.3.4
