Description (partial)

MDS 9148s may respond to SNMP get of  "cefcPhysicalStatus" ( iso. )  with integer 3 which means unsupported for power supplies that are installed in the 9148s.

Some OEM products use SNMP and poll Cisco switches using  "cefcPhysicalStatus" ( iso. ),  to check power supplies.  The correct response should be "2" or "supported" if the power supply is present.

On the MDS 9148s, if the power supply is present by powered off ( AC input missing or the power switch is in the "0" or OFF position, the switch will respond to the query for that supply with integer 3 ( unsupported ).

This is incorrect, the response should still be integer 2 ( supported ).
