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 condition. 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. . Table 1-1.

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.
.
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 sides of the connectors.
