1
The power supply is an auto-ranging power supply. It does not have to be
recon:figured to operate over its rated operating ranges. However, the system
should not be operated at voltages between the two input voltage ranges.
2
Typical load assumes 192MB memory, two internal disk drives, two
peripherals, PSI I/O card, 802.3 LAN, and a 64MHz CPU.
The power supply can provide power for up to three internal peripherals.
