We currently have a Comdial DXP and believe the CPU is going out or has gone out. It is a DXCPU-68K SW rev 12A

If we ordered a new CPU and swapped it and the new cpu has a different sw than the old one will any information be lost. The DXRam is also Rev B the system is very old... Thanks for all helpful replies.

You have multiple areas for concern. Yes all be lost unless you can restore your old database. Depending on the level of CPU your existing Services board may have to be upgraded. Your new CPU may have restricted software that won't allow specific telephones to work on it.

Well the new cpu we got had a newer sw version than the old one, we swapped the old ram to the new board, and to no avail there was no communication with the phone system, i could see the lights going green on the board and on the cpu,, replaced with old board and orig memory...

I also noticed in the terminal that I see some failures happening..
