Replacing a Failed Command Switch with a Cluster Member
To replace a failed command switch with a command-capable member in the same cluster, follow these
steps:
Step 1 Disconnect the command switch from the member switches, and physically remove it from the cluster.
Step 2 Insert the member switch in place of the failed command switch, and duplicate its connections to the
cluster members.
Step 3 Start a CLI session on the new command switch.
You can access the CLI by using the console port or, if an IP address has been assigned to the switch, by
using Telnet. For details about using the console port, refer to the switch hardware installation guide.
Step 4 At the switch prompt, enter privileged EXEC mode:
Switch> enable
Switch#
Step 5 Enter the password of the failed command switch.
Step 6 Enter global configuration mode.
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 7 Remove the member switch from the cluster.
Switch(config)# no cluster commander-address
Step 8 Return to privileged EXEC mode.
Switch(config)# end
Switch#
Step 9 Use the setup program to configure the switch IP information. This program prompts you for IP address
information and passwords. From privileged EXEC mode, enter setup, and press Return.
