Power Supply

The 200-Watt (W) power supply can operate from an AC power source of 115 volts AC (VAC) at 60 hertz (Hz) or 230 VAC at 50 Hz. The power

supply provides the DC operating voltages and currents listed in the following table.

Table 2. DC Voltage Ranges

DC Power Cables

DC Power Connector Pin Assignments

The power-supply output voltages can be measured at the back (wire side) of the DC power connectors without disconnecting them. Figures 1

through 4 show the wire side of the connectors.

NOTE: The power supply produces DC voltages only under its loaded condition. The DC power cable connectors must be connected to

their corresponding power input connectors on the system board or drives in order to measure these voltages.
