Table 2.1 shows possible ethernet connections for clusters that use a single
master controller.

If a secondary connection is used and the primary connection fails, the system
will automatically switch to the secondary connection.
Clusters that use an alternate master use onboard ethernet connections for
both master and alternate as shown in Table 2.2. Dial up and serial
connections are not supported.
