Last week I realigned a MICS 6.1 that had 4 analog expansion modules in order to add 3 additional mod's. I put mod 3 and 4 in series and 5 and 6, making 16 analog on fiber port 3 and another 16 on port 4. When I restarted the system it scattered the DN and port #'s across the four modules at random. I shut the system down and added a fifth analog and sixth digital and a line mod on eight. The corruption remained on the first 4 but 5,6 and 8 came up normal. I was forced to completely Initalize and reprogram the entire system from scratch. ?? is there a way to do this without the corruption, or should I have re-inited from the beginning
