56 HP StorageWorks Disk Array XP1024: Site Preparation Guide
30-amp, three-phase power
When the disk array uses 30-amp, three-phase input power, HP Disk Array
XP1024 DKCs and DKUs have two power cords each as shown in the
figure below.
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 3760PDG. Be sure to install Russellstoll 3934 (alternate,
9C34U0) or 3754 (alternate, 39R34U0W) socket receptacles between the
power distribution panel of the building and the power plugs for the units.
The power cords provided with your disk array are non-shielded, type ST
or equivalent with four #8 AWG (minimum) conductors terminated at one
end with an assembled plug connector.
