Proliant 7000, CR46 System Interlock On

[Mark_750]

We recently moved two Compaq Proliant 7000 units (due to their size, that's another story). One unit now refuses to power on, and the system interlock led is on.

From what I understand the two causes of this LED are the system I/O board becoming loose and not seated properly, or an interlock switch is active. I've reseated the board multiple times and pulled most of the machine apart to reseat the panels.

I see two interlock switch connections on the i/o board, and processor board, but no physical interlock switch - both seem to be disabled with a wire loop.

Any other ideas to get this machine running?

hi mark

there is also a cable from the io board which is part of the interlock.

check that one.

there are not too many cables. and it is not the scsi cables.#

best regards

Didn't seem to do it. I went as far as pulling the wire loop out of the header and testing it with a multimeter, and it passed.

I don't see anything else that it can be...
