Using Recovery Procedures
Step 11 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; on a member switch to 31 characters. Do not use -n, where n is a number, as the last
characters 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.
Step 12 When prompted for the enable secret and enable passwords, enter the passwords of the failed command
switch again.
Step 13 When prompted, make sure to enable the switch as the cluster command switch, and press Return.
Step 14 When prompted, assign a name to the cluster, and press Return.
The cluster name can be 1 to 31 alphanumeric characters, dashes, or underscores.
Step 15 After the initial configuration displays, verify that the addresses are correct.
Step 16 If the displayed information is correct, enter Y, and press Return.
If this information is not correct, enter N, press Return, and begin again at Step 9.
Step 17 Start your browser, and enter the IP address of the new command switch.
Step 18 From the Cluster menu, select Add to Cluster to display a list of candidate switches to add to the cluster.
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 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 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 3 At the switch prompt, enter privileged EXEC mode:
Switch> enable
Switch#
Step 4 Enter the password of the failed command switch.
Step 5 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.
