System Unit

The following subsections provide service-related information about the
computer.

System Power Supply

The 230-W system power supply can operate from an AC power source of
115 VAC at 60 Hz or 230 VAC at 50 Hz. The system power supply provides the
DC operating voltages and currents listed in Table 1-1.
NOTE: The power supply produces DC voltages only under its loaded condi-
tion. Therefore, when you measure these voltages, the DC power connectors
must be connected to their corresponding power input connectors on the system
board or drives.

Maximum continuous DC output power shall not exceed 230 W. Maximum combined load on
+5 VDC and +3.3 VDC shall not exceed 170 W.

VFP (volts flea power) — sometimes called "standby power."

Pin Assignments for the DC Power Connectors

The power-supply output voltages can be measured at the back (wire side) of
the connectors without disconnecting them. Figures 1-6, 1-7, and 1-8 show the
wire side of the connectors.
