Using Recovery Procedures
Replacing a Failed Command Switch with Another Switch
To replace a failed command switch with a switch that is command-capable but not part of the 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 new 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, see 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 Use the manufacturing default configuration, or set up the switch through the management module.
Step 7 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.

Step 9 Respond to the questions in the setup program.
When prompted for the host name, recall that on a command switch, the host name is limited to 28
characters. Do not use -n, where n is a number, as the last character in a host name for any switch.
When prompted for the Telnet (virtual terminal) password, recall that it can be from 1 to 25
alphanumeric characters, is case sensitive, allows spaces, but ignores leading spaces.
