Operating Configuration
Do not use the setup configuration as your working configuration. It lacks fault
tolerance. Add fault tolerance to the setup configuration by connecting a backup
system console and a second Ethernet switch or hub. See Operating Configuration on
page 10-3.
Operating Configuration
After you have completed the setup configuration tasks, you can expand to the
operating configuration by adding a backup system console and second Ethernet
switch or hub. Figure 10-2 shows primary and backup system consoles connected to
separate Ethernet switches.
Create the Operating Configuration
The primary system console is the system console installed in the setup configuration.
Switch 1 is the switch installed in the setup configuration.
The backup system console and Switch 2 are added for fault tolerance. You can add a
backup system console and switch to the setup configuration online. Do not add a
backup system console until you have completed Setup Configuration on page 10-2.
The Ethernet switches or hubs are linked by a cable that enables the system consoles
and server to be on the same subnet. This cable connects the cascade port of one
switch to an open port on the other switch.
