When a PSU monitored by the plugin "Cisco Nexus Switches: State of FRU Power Supplies" had no power, the service went to UNKNOWN. It now goes CRITICAL.

In addition we changed the conditions under which a service is discovered. Powered off FRUs in the following state have not been discovered before, but are now (quoted from the MIB):

offEnvPower(5): FRU is powered off because of power problem in the FRU. For example, the FRU's power translation (DC-DC converter) or distribution failed.

FRUs disabled administratively are no longer discovered:

offAdmin(3): Administratively off.
