Preparing for installation
60-amp, three-phase power
When the disk array uses 60-amp, three-phase input power, HP Disk Array
XP1024 DKUs have two power cords, but the DKC has no external power
cords as shown in the figure below.

In this configuration, an internal cable from the first (R1) DKU provides
power to the DKC. If one power source malfunctions, the other power
source assumes the total load, providing uninterrupted operation. HP
recommends that each power cord have a separate electrical circuit as its
source in case of a circuit failure. Each power-supply cord is supplied with
an attachment plug type Russellstoll RS460P9W. Be sure to install
Russellstoll RS460C9W or RS460R9W socket receptacles between the
power distribution panel of the building and the attachment plugs for the
unit.
The power cords provided with your disk array are non-shielded, type ST
or equivalent with four #4 AWG (minimum) conductors terminated at one
end with an assembled plug connector.
