HP StorageWorks 200 Storage Virtualization System owner's guide (AE071-96004, October 2006)

AC line voltage
requirements
This section l
ists the AC power recommendations. The rack has four power cords, but
only the lower two are used for the controller. The upper two power cords are reserved
for an optional second controller. In case of a failure of the power source for one cord,
the power requ
irements, and therefore the current requirement for the remaining power
cord, will double.
For details about electrical specifications, cabling, and connectors, see the HP
