These are the +12V DC output rails. They provide the main power to your device.

Here is the for revision 2 of the D220P-01. (Revision 1 had slight differences in the sense wire – this is specifically for the D220P-01 REV:02).

To enable the 12V output without a Dell system, you typically need to jumper Pin 5 (Remote) to Ground . Users often report the LED turning from orange (standby) to green (active) once properly shorted.
