ML570 repetitive power on

 

ML570 repetitive power on

I'm working on a Proliant ML570T01
It has redundant power supplies, redundant fans, Two processors.
When the power cord is connected to the power supplies, all the fans spin up for about two seconds, then they go off, after about eight seconds they come on again, and then go off.
This continues for as long as the power is plugged in.
I've tried one power supply at a time, disconnected powerand cables to all the peripherals (drive cage, etc.), disconnected the power switch, reseated peripheral board, memory board, processors.
No change
Any suggestions?
Thank you.
