Notes

• See Section 4.3.3 for power cord information and power cord routing choices.

• The high voltage PDUs shown in this figure are 24A rated.

• One Vertical-Mount PDU Bracket Kit with High Voltage Cables is required for this installation.

• For PDU-1, there are 8 Y-cables connected to the PDU to support 16 servers in the above figure.

Each of the 8 Y-cables is connected to two servers.

• For PDU-2, there are 6 power outlets still open (marked with **). 16.8A of current capacity has been

allocated for the servers. The total current draw from the remaining outlets by other off-rack devices

must not exceed 7.2A for the 24A PDU.

• No power cords should be connected to all the unused outlets marked with Ø.
