Make sure you check the following:

• Your power supply is a REGULATED 12V power supply and at least 5A
• Check to see if the green LED on the picoPSU is lighted up

If it still does not work, please contact us.

Yes. You will need to desolder the inductor (grey) that is obstructing the ethernet ports on the board and solder a lower profile inductor. The Intel D201GLY series boards consumes only 0.4A on the 3.3V rail (this inductor belongs to 3.3V rail) and get a 10x10mm inductor (about 2-4uH with a height under 4mm, if possible). This can be purchased at: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=513-1332-1-ND

Please make sure you are not using any devices that consume 12V (for example, 3.5" drives or CDROMs).
This PSU cannot power 3.5" drives and 5.25" CDROMS. Use 2.5" drives or SlimCDs or flash drives instead.

In most cases, it will work without any problems. If you need more power, you can get the 20-pin to 24-pin adapter or our 24-pin ATX power supplies (M4-ATX and the picoPSU-150-XT).
