The status of the main Power Supply. on means that the power supply is present
and fully operational. off means that the power supply is totally off (and
obviously only applies to systems with a redundant power supply). faulty means
that the main power supply is delivering power but that a component of the
power supply is faulty. This applies to systems like SwitchBlade which have 3
power supplies but do not provide individual power supply monitoring. Also,
in the case of SwitchBlade, power supply status includes the status of the fans
in the power supply.
