About the power distribution unit 41

A PDU can distribute power to a maximum of four power supply units that can be installed in two or more servers. Therefore, if there are three or four servers installed in a rack, then you must install a second PDU.

Note: The power supply module installs in the server. It does not refer to a UPS, which is a separate unit on the rack.

PDU terminal blocks and wiring diagram

A PDU consists of eight terminal blocks within a metal enclosure. Before installing the PDU, connect the terminal blocks so that each output connector receives power from a separate -48 V dc branch circuit, as shown in the following diagram. Use AWG 10 wires for these connections.

Single PDU wiring diagram

DC power input

DC power input into the distribution unit connects BAT-1 to BAT-4 and BR-1 to BR-4. Refer to the preceding diagrams for the location of these terminals. Connect the input wires before installing the PDU on the rack.
