I have a used MICS with 6.0 (NT7B64YU Rel 1 MICS DR6.0) software that was working when I removed from service. Wanted to get it going as I used my last one yesterday and need a spare. 2 non-CLID cards on KSU, No expansion card. However, when booting up, I get a "Config error" on the screen of a M7208 and "In Maintenance" on the M7310. No other phones or anything else connected. According to an old post on another forum the problem was the expansion card was in the wrong slot. Obviously not in this case. What now?
