BSC mode

The value can be Non-BSC mode (default) or BSC mode (set when the
system is a dual-bus system).

A dual-bus system consists of the master and slave BSC systems. You can
specify the master and slave BSC systems (one master and one slave) and
change the settings under the guidance of maintenance engineers. Set the
master and slave BSC systems to master and slave BSC modes
respectively.
NOTE
Ensure that the BSC signal cable between the master and slave BSC systems is properly
connected and that BSC-related hardware is properly installed.
