I have a system that has been installed for some time in a 5 slot frame (3 Cards) ACS Processor, Line/Extension Expansion, and Voice Mail. Last week by accident I removed the memory batteries while the system was turned off. By By setup. When I powered the system back up the expansion card and voice mail would come up for a few seconds (Green Power LED) and the power back down. The ACS came up OK and stays up. All of its functions appear to work properly. I reinstalled an older system backup and most everything seems to work except I can't get the two cards to come up. I tried reseating the boards several times but that has not helped. Any ideas??
