I would do the same and for the same reason. Sounds like a bad power supply on the board which means changing the KSU and reprogramming.

What I would do:
a) Bother each user and take note of their phone's model, buttons and their programming (Yes it's a PITA, but they'll appreciate it as they won't have to reprogram any buttons afterwards.) While there also note the ext's number & port. Example: 223/126 You'll need this on the bench!
b) Take note of all "system" programming
c) Pre-Program another CICS with the same level of software on the bench. When programming each extension, connect the same model of phone as that extension had with the old system or you're wasting your time.
d) Return to client either during off hours or preferably at a "quiet" time during the day...usually lunch hour, and replace the KSU.

All programming will be as it was if you did it right and you'll be the hero. Total "Client Down Time" should be 5-10 minutes.
