DC Voltage Ranges
OptiPlex E1 systems are equipped with a switch-selectable (115/230 VAC) universal power supply that can operate from standard AC power outlets in all countries.
The system power supplies provide the DC operating voltages and currents listed in the following table.
1 The combined load on the +5-VDC and +3.3-VDC outputs should not exceed 105 W on the low-profile system.
2 Withstands surges of up to 11.0 A to support disk start-up operations.
3 VFP (volts flea power) — sometimes called "standby power."
DC Power Cables (Low-Profile Chassis)
NOTE: Each 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.
