HP StorageWorks XP24000/XP20000 Disk Array Site Preparation Guide (AE002-96055, September 2010)
an HP XP24000 disk array with the 30-amp power option to comply with these local codes. Your
electrician knows the appropriate code requirements for your location/site.
XP20000 electrical specifications
XP20000 AC line voltage requirements
The AC power requirements, shown in Table 24, are essentially the same for primary and secondary
racks. Each rack operates on 200 VAC nominal, 20 amps, 50 or 60 Hz, single-phase power. An
independent branch circuit and a circuit breaker are required for each AC input power cord.

Important notes:
208 VAC is 60 Hz only. 220 VAC and 240 VAC are 50 Hz only. Rated line current per power cord
is the maximum allowable current under worst-case conditions. This value applies to each individual
power cord and is specified in RMS amperes. For the second rack, four power cords and circuit
breakers are strongly recommended even though a minimum configuration containing only one
expansion disk chassis requires only two power cords and two circuit breakers. If a second expansion
disk chassis is added to the second rack, four power cords and four circuit breakers are required.
XP20000 HP power cables and connectors
HP offers the following AC power cables and connectors, which you can order individually (four of
each are required per primary or secondary rack):
• AE190A/AU, option 001 4.5 m power cord w/NEMA L6-20P plug
• AE190A/AU, option 002 4.5 m power cord with stripped ends
• AE190A/AU, option 003 4.5 m power cord w/ IEC 309 plug
• AE190A/AU, option 004 4.5 m power cord w/ CEE7/7
• AE190A/AU, option 005 4.5 m power cord w/NEMA L6-30P plug
You can supply your own power cables as long as they meet a 20-amp rating, fit the IEC320-C20
PDU inlets, and meet local codes.
XP20000 power cabling
The XP20000 primary rack has four separate connections to 200 VAC, single-phase, 20-amp power.
The AC power inputs to the primary rack are distributed to four power distribution units (PDUs) as
