I have a two cabinet 1100. No issues for 9 years. Today I move it. System locked up, no dial tone, phone says INITIALIZING. This is only with 1 phone attached. I disconnect the expansion cabinet, all trunks and just one phone, it does it again. I reboot and it comes back, no issue again for 5 hours and then again locked up. I took a backup before moving it. I also have backups from long ago. Should I reseat all the cards? I don't need the expansion cabinet, can I leave it disconnected or should I remove that expansion card? What do you recommend?
