North American AC power cabling

The XP10000 racks each require 20-amp, single-phase 200 VAC power supplied by
four power cords with plugs, four receptacles, and four main disconnect devices (circuit
breakers). If the second rack contains only one disk chassis, only two power cords and
breakers are required, but four are required if you plan to add another disk chassis.
The XP10000 comes from the HP factory with the AC power cords and plugs you have
ordered. Plug types rated for 30 Amps are specified under the heading,
earlier in this chapter. The opposite end of the power cord connects to the XP10000
power distribution unit input, which is a type IEC320 C20 connector.
Connect each AC power cable to a separate receptacle on a separate circuit breaker,
and connect each pair of power cords (the left pair and the right pair) to separate
distribution panels to ensure power fault tolerance.
CAUTION:
Do not apply power until instructed to do so by HP. An HP representative should be
present whenever the disk array is being connected to a new power source.

Branch circuit requirements

To protect the disk array, your building must be wired correctly. Each supply ("hot")
conductor must be protected by a short-circuit protective device and by an overcurrent
protective device. The table listed under
specifications for the overcurrent protective devices required for single-phase operation.
All protective devices must comply with national standards of the country where the
units are to be installed. If a protective device interrupts any supply conductor, it must
also interrupt all other supply conductors.
