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.
