To avoid extension and trunk renumbering if certain PCBs are recognized first, set the
PCB Block option using Program 90-05-01, Menu 3 for each of the PCBs until the
system has reset. Then, unblock the PCBs using Program 90-05-01, Menu 4 in the
correct order to retain the proper system numbering (Use Programs 10-03 or 90-13-03
prior to performing a cold start to record the current slot definitions.).
Without a USB Flash drive installed in the CCPU, turn the system power off by first powering
