Switch 4 was off and the battery switch was on. The KSU is also protected by a small UPS so I do not suspect the database to be corrupted by a power fluctuation. The system only restarted properly after I removed the voicemail card. I put the voicemail card back in the system and it would no longer restart. I had not changed any dipswitch settings up to this point. My next step was to shut down the system (voicemail card installed), turn off the battery switch and switch 4 to initialize the system. It then started up properly with the voicemail card installed. I reloaded the database and it has been running for 4 days without any problems.

I suspect two possible explanations. (1) the cmos battery is marginal, or (2) the customer has made mistakes while in the programming mode. They were trying to extend the amount of time before messages were automatically deleted.

What do you think?
