Peripheral Power Supply/AC

The system has one peripheral power supply/AC input (PPS/AC) installed in the rear of the system. The PPS/AC, also known as PPS 0 to the system software, has the AC switch and AC cable socket.

Additionally, the peripheral power supply/AC provides DC power for the CD-ROM/tape drives tray and precharge power for hot-plugging boards and PCMs.
