8.7 Commissioning a Dual-Bus System

Context
The dual-bus system consists of one master and one slave BSC system. You can
specify one master and one slave BSC system (UPSs in the same system cannot be
set to both master and slave BSC systems) during initial startup, and change the
settings under the guidance of maintenance engineers when needed. Set the BSC
master and slave systems to master and slave modes respectively.
Procedure
Step 1 Connect BSC cables.
