Sun Enterprise 6500/5500/4500 Systems Reference Manual

Peripheral Power Supply (PPS)

The green LED is to the right of the yellow LED on the peripheral power supply. The green LED indicates that the peripheral power supply is operating, but does not necessarily indicate that the DC outputs are within specification.

When the peripheral power supply module yellow LED is lit, a DC power output has malfunctioned or the voltage level is out of specification.

The peripheral power supply produces +5 VDC and +12 VDC current. The current is available for peripherals such as a tape drive and/or CD-ROM drive. In addition, the +5 VDC output of the peripheral power supply is available at the center plane for current sharing with the +5 VDC outputs of the power supply modules.
