Defining Backup Ports
Use the Port Backups menu under the Configuration Panel to
define up to 6 master/slave port pairs. If the connection to the
master port fails, the slave port will automatically take over.
For greater reliability, primary and secondary ports should be
located on different hubs. Use the following menu to specify
and activate port backup pairs.
