Full Pinout for these pin compatible Power Supplies.

Astec/Emerson DS450-3/DS550-3, Sun Fire X4100/X4100 M2, X4200/X4200 M2, Dell Poweredge 1850, 2800, 2850, 2950, AA23290, AA23300, 7000814-0000, NPS700AB, N750P-S0, AHF-650-12-Y Full Pinout Assignment.

Astec manufactures the DS450-3/DS550-3.
The Sun Fire X4100/X4100 M2, X4200/X4200 M2 servers use the DS550-3 PSU.
The Dell 1850 AA23300 PSU is really a DS550-3 in disguise.

Dell 1850 AA23300 PSU and Astec DS550-3 voltage control modification 12V-14.2V.

Connect PS On and PS Kill to ground to power up.

Pin B2 may be the analog fan control voltage input or may be left spare.
Connecting B2 to ground may slow fan speed and/or connecting to 3.3v may increase fan speed.

The accompanying Pinout from the Sun Fire™ X4100/X4100 M2 and X4200/X4200 M2 Servers Service Manual is for verification purposes.
