A few years ago I purchased (used) a Fujitsu 4100 fan tray.  It's comprised of ten (10) 48-VDC fans.

It uses a parallel computer-type cable for power and alarms.  I'm not interested in the alarms.  I've not found any documentation about the fan tray and/or cable.

Any of you have any information and/or ideas on how to power these fans?

From what I can tell and the fan wires go into a circuit board.  If need be, I can bare it down to those wires.

Tnx & 73,
