CPU-Redundancy (Redundant Basic System Elements)

The voting between both BSEs (between the redundant CPU pairs) is performed automatically
by the M-CPU (automatic voting with CPU redundancy).
You define the criteria for a voter switchover in the Redundancy Table (see also the
description of the Priority Levels in sections
Connection between both BSEs over HSL
The High Speed Link (HSL) is used for the synchronization of both redundant BSEs
(C-CPUs).
For CPU redundancy the HSL-connections are installed permanently at the back of the
mounting rack corresponding to the predefined CPU pairs.
Predefined BSE pairs 1/2, 4/5, 7/8, in the mounting rack for 9 slots (CM-2834).
Predefined BSE pairs 1/2, 4/5, 7/8, 10/11, 13/14 in the mounting rack for 17 slots (CM-2836).
