Power Supply Lamps (hot-swap power supply model only)
The power supply on the rear of the server has two lamps.
NOTE: The server equipped with an optional power unit can continue
the operation with the normal power unit if the other power unit is
defected (redundant function). The defected power unit can be
replaced with a new one in the hot-swap mode without power
interruption.
