Folks, I worked with Harry on the phone on this a bit tonight.
It appears it may well be a hardware problem. I finally gathered my courage, trusted IBM engineering, and powered-up the system *with the CPC module completely removed* The symptoms - what worked, and what didn't, on the SE - with the CPC removed were *exactly the same* as when the CPC was installed! It's clear that for some reason either the CPC isn't getting powered-on, or the OS/2 side *thinks* it isn't powered on. Or the SE is totally unable to communicate with the CPC. I suspect the CPC isn't powering-on; it doesn't even get warm. Harry recalls a similar situation on his MP3000, where a failure to POR was traced to the RS422 cable from the OCAs (AKA 'power supplies'!) being disconnected from the appropriate card on the PCI bus. So I'm concentrating my investigations on this area. The hardware console does report a 'power problem' each and every time the machine is started - but the FRU reported as causing the error is the 4mm DAT! I can't see how that can be to blame. I ask again: has anyone on the list seen similar symptoms? Failure to POR or CPC appearing powered off, on a MP3000. I could use some help here!

You do need to be able to do a POR, however. After that you can just IPL manually. If the CPC wasn't working you would be reading about it in your hardware log. What you describe is the SE is unable to issue control commands to the CPC and receive returned information. > > > >What seems to be missing is control signalling between the SE and the CPC.
