tomfanning / Dell Poweredge 1855 1955 PSU AHF-2DC 2100W (12v 175A) Pinout.txt
Created January 14, 2016 15:46
Dell Poweredge 1855 1955 PSU AHF-2DC 2100W (12v 175A) Pinout.
Works on 220-240v only.
Is compatible with US home type split-phase 220VAC but be cautious as to the correct wiring of the plug.
All of the important pins are included.
Connect PS On (A5) and PS Kill (B3) to ground to power up.
A5 = PS On
B3 = PS Kill
