I tried installing the 400 line card into the final slot. Both cards in the in slot 4 & 5 wouldn't come up. Replaced the main processor card. I had a 308 in slot 1&2 and the partner messaging card in slot 4. All cards came up. It didn't matter that v-mail port weren't programmed. I reprogrammed the phone system and all is good. The faulty processor board smelled like burned plastic! Thanks for the help! :banana:
