Specifications A-3
1
The power supply auto-ranges to the AC voltage and frequency. It does not have to be reconfigured to oper-
ate over its rated operating ranges.
2
The typical AC Input Power rating is based on a configuration of 3 CPUs, 3 internal disks, 1 memory con-
troller, 288Mb of memory, 2 HP-HSC cards, 1 HP-HSC expansion card, 1 HP-PB FDDI and 1 F/W SCSI
card.
