PMB LEDs and Code Wheels
Up to 16 Central Subsystems can be linked, via Platform Management Boards (PMBs) to a
single PAP unit, to provide a single point of administration and maintenance.
Each PMB is equipped with two code wheels used to identify each Central Subsystem and
each CSS module in your configuration. These code wheels are set prior to shipping (factory
default setting), according to configuration.
