NOTE: The red dot in the jumper denotes pin 1. |
| Jumper Setting | Jumper | Description |
| Pins 1-2 jumpered (Normal mode) |
 |
In Normal mode, system setup settings and installed passwords are retained when the computer starts up. In this mode, an automatic recovery is attempted if the BIOS detects that any of its main blocks are corrupted. |
| Pins 2-3 jumpered (Maintenance mode) |
 |
Starting the computer with the jumper set in Maintenance
mode automatically starts the system setup program, adds the Maintenance option to
the menu bar, and displays the Maintenance screen. This screen provides the
following option. NOTICE: Entering Maintenance mode returns all settings in the system setup program to their defaults. Dell strongly recommends that you record or print all current settings before entering this mode so that you can correct them when the computer is reset to Normal mode. Clear All Passwords — Disables a forgotten password so that you can access the computer and assign new passwords. For the complete password procedure, see "Clearing Forgotten Passwords" in the Solutions Guide. |
The 145-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.
|
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 to measure these voltages. |
| Voltage | Range | Maximum Output Current | Notes |
| +3.3 VDC | +3.14 to +3.47 VDC | 10.00 A | The combined load on the +3.3-VDC and +5-VDC outputs cannot exceed 85 W. |
| +5 VDC | +4.90 to +5.25 VDC | 16.00 A | The combined load on the +3.3-VDC and +5-VDC outputs cannot exceed 85 W. |
| –5 VDC | –4.50 to –5.50 VDC | 0.300 A | |
| +12 VDC | +11.40 to +12.60 VDC | 4.5 A | The +12-VDC output can withstand surges of up to 11.0 A to support disk start-up operations. |
| –12 VDC | –10.80 to –13.20 VDC | 0.300 A | |
| +5 VSB | +4.75 to +5.25 VDC | 1.2 A | The +5 volts standby (VSB) is sometimes called volts flea power (VFP). |
The power-supply output voltages can be measured at the back (wire side) of the DC power connectors without disconnecting them. The following figures show the wire side of the connectors:
DC Power Connector P1
| 1 | +5 VDC (red) | 11 | PSON#2 (brown) |
| 2 | Common (black) | 12 | Common (black) |
| 3 | +5 VDC (red) | 13 | Common (black) |
| 4 | Common (black) | 14 | Common (black) |
| 5 | PWRGOOD1 (orange) | 15 | –5 VDC (white) |
| 6 | +5 VFP (purple) | 16 | +5 VDC (red) |
| 7 | +12 VDC (yellow) | 17 | +5 VDC (red) |
| 8 | –12 VDC (blue) | 18 | +5 VDC (red) |
| 9 | Common (black) | 19 | Not connected |
| 10 | Common (black) | 20 | +5 VDC (red) |
1 Pin 5 — PWRGOOD is a status signal generated by the power supply to notify the computer that the DC operating voltages are within the ranges required for proper computer operation.
2 Pin 11 — PSON# is activated by pressing and releasing the power button while the power supply is in standby state. Activating PSON# connects the power supply's PSON# input to ground, thereby switching the power supply to full-on condition.
