    The master chassis’ address must be “00” while slaves must be “01” through “99.” When the Pro Switching System II has been installed and first powered up, it will automatically go into the configuration mode. The initial configuration parameters are rack-address selection, site selection, Cntl-In/Out data rate, and Aux data rate.
