Ac Line Voltage Requirements - HP StorageWorks XP10000 Owner's Manual

AC line voltage requirements

38
This section lists the AC power recommendations. Each rack has four
power cords. In case of a failure of the power source for one cord, the
power requirements, and therefore the current requirement for the
remaining power cord, will double.
For details about electrical specifications, cabling, and connectors, see the
HP StorageWorks XP10000 Disk Array Site Preparation Guide.

Rated line current per power cord
Number of power cords per rack
Recommended circuit breakers
1 60 Hz only.
HP requires a separate branch circuit for each power cord connection. The
circuit breaker for each branch circuit must have a minimum rating of 20
amps. Breakers must be easily visible and accessible so power can be
quickly removed in an emergency. Local building electrical codes may
dictate specific additional circuit breaker requirements. Consult your
electrician or local code for the requirements in your location.
If you have multiple power sources, such as a UPS, connect two of the
power cords for each cabinet to each power source for maximum protection
from power outages. Consult your local HP service representative about
which power cords are to be attached to the two power sources.
