SNMP OID for System Status LED's

I am trying to locate the proper MIB and OID location, to determine if the system attention light is on IBM-702x servers running 5.x.

Currently, we get this on our Blade Centers Management Modules at location: 1.3.6.1.4.1.2.3.51.2.2.8.2.1.1.7.xx were xx is the actual Blade number. A value of 1 indicates the LED is on.
