I have an option 81c that currently has 3 shelves down from a lightening strike. I have powered the stack up and tried to enxp both 1, 2, and 3. I get a npr327 and the display on the Controller card simply shows a double 0 0. Normally the cards show c 0 and then flash 0 0 and back and forth until the controller card is enabled. Does anyone know what the double 0 0 represents and any suggestions to get this switch up and running would be most appreciated. I have moved another controller card from and working shelf and get the same results.
