Application
The MCUAs of the S7703 are installed in slot 4 and slot 5.
The S7703 must have at least one MCUA. You can install one or two MCUAs. If only one
MCUA is installed, it can be installed in either of the MCUA slots. To improve reliability of a
key device, you can install double MCUAs. When the master MCUA fails, the slave MCUA
substitutes for the master MCUA automatically to prevent service interruption.
