depending on its model.
The server supports one or two PSUs.
The server supports AC or DC PSUs.
The PSUs are hot-swappable.
The server supports two PSUs in 1+1 redundancy.
The same model of PSUs must be used in a server.
The PSUs are protected against short circuit. Double-pole fuse is provided for
the PSUs with dual input live wires.

For a server configured with one or two 1500 W Platinum AC PSUs:
● When the input voltage is from 100 V AC to 132 V AC, the output power drops to 1000
W.
● Two 1500 W AC Platinum PSUs can serve as 1700 W PSUs.
