Auto-Ranging
Power supply that automatically senses and adjust itself to the proper input voltage range
(110 VAC or 220 VAC). No manual switches or manual adjustments are needed.

Dropout
A condition that allows the line voltage input to the power supply to drop to below the
minimum operating voltage.

Latch Off
A power supply, after detecting a fault condition, shuts itself off. Even if the fault condition
disappears the supply does not restart unless manual or electronic intervention occurs.
Manual intervention commonly includes briefly removing and then reconnecting the supply, or
it could be done through a switch. Electronic intervention could be done by electronic signals
in the Server System.

Noise
The periodic or random signals over frequency band of 10 Hz to 20 MHz.

Over-current
A condition in which a supply attempts to provide more output current than the amount for
which it is rated. This commonly occurs if there is a ‘short circuit’ condition in the load
attached to the supply.
