Defining Port
Backups
Select Backup Link Control (described in Table 10) from the Port Configuration
screen to define up to 15 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 menu in
Figure 11 to specify and activate port backup pairs.
