(am I right?) in an R12K/225, but it didn't work, just gave a red light. Tried a second core from an Octane/300
CPU, same result.
Putting the R10K core back in, still a red light. Worked ok before the swap attempt. Something gone fubar...
I can't think of any other details that would be relevant.
Ahh, the red light. Unless the PM is baffed itself, check the compression pins in the connector socket. It's not so much that the pins work loose or misalign, but its fairly easy to gunk up one of the contact surfaces, or have a miscellaneous bit fall into the socket and cause contact problems. The R12k-300 should have worked fine, as should the original R10k-225, they have the same voltage requirements.
