Hi I have a 400W PSU from a Cisco Catalyst 4006 and would like to know the pin out for the rear connector. In particular I am looking to identify the sense pins as the unit will not power-up with out these sensing the
+12v rail. For information sake I am trying to use this 33.3A 12V psu to power and amateur radio rig!Many thanks for any help you may be able to provide.

I know of no reverse engineering that's been done on Cisco's power supplies. If there is, I happen to have several catalyst 5500 power supplies that I'd be willing to ship to anyone for a minimal amount.
-however- My suggestion to you is to save your frustration with it and buy an old PC ($5 - $10) and strip it's power supply. If the PC is not too old, it should have a decently large power supply. There are several web sites that outline the use of ATX power supplies for other purposes.
