I have a site that experienced a CICS 4.2 failure. A few of the ports stopped working. When you plug a phone in the LEDs will not stop flashing and you cannot get dialtone. I tried to swap the ports and found that at least 3 other ports were doing the came thing. I have replacement CICS cabinet coming. When I swap the cabinet out, do I have to completely reprogram the system or does the site information reside ont he Software feature card?
