44 HP StorageWorks Disk Arrays XP128/XP1024: Owner’s Guide
AC line voltage
The following AC power recommendations for the HP StorageWorks Disk
Array XP128 are for each power cord. Each array frame has two power
cords (with the AC power cord option there are four cords). In case of a
failure of the power source for one cord, the power requirements and the
current requirement for the remaining power cord will double.
Table 6 (page 44) lists the basic AC power requirements for a 50-amp
single-phase XP128 DKU. Table 7 (page 44) lists the basic AC power
requirements for a 30-amp single-phase XP128 DKU.
