5.4.2.2 Processing and Communication Element(s)
After removing the processing and communication element from the board rack, the function
of the affected subsystem is naturally not present.
Since for the replacement of a processing and communication element a shutoff of the power
supply is not required, the function of other basic system elements and their subordinate sys-
tem elements is maintained.
After the insertion of the new processing and communication element, this performs a startup.

For the replacement of a serial interface module first the basic system element (carrier mod-
ule) must be removed from the board rack. For this, please consider the previously mentioned

quired, the function of the basic system elements and their subordinate system elements is
