I am reinstalling a Prologix for a customer that has downsized from 200 phones to 35. There is only room on the wall for one cabinet. How do I tell the Prologix that it is only an "A" cabinet now? I have rearranged the boards the way I want them, and the system sees them properly, but it also still sees the B and C cabinet, albeit as empty. Is it always that way, or is there something I need to change in either hardware, software, or both? Along the same lines - does anyone know the number/name of the hardware installation manual for the Prologix? It is a G3CsiV13.
