Replacing a Failed Command Switch with Another Switch
To replace a failed command switch with a switch that is command-capable but is not part of the cluster,
follow these steps:
Step 1 Insert the new switch in place of the failed command switch, and duplicate its connections to the cluster
members.
Step 2 Start a CLI session on the new command switch.
You can access the CLI by using the console port, by using the E
thernet management port, or, if an IP
address has been assigned to the switch, by using Telnet. For details about using the console port, see
the switch hardware installation guide. For details about using the Ethernet management port, see the
“Using the Ethernet Management
Port” section on page 13-22 and the hardware configuration guide.
