Description: 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.
