If a password has been configured on the candidate switch, you are prompted to 
enter it and your username. You can add multiple candidates at the same time if 
they have the same password. If you enter a password that does not match the 
password defined for the candidate or if you enter a password for a candidate that 
does not have a password, the candidate is not added to the cluster. In all cases, 
once a candidate switch joins a cluster, it inherits the command-switch password. 
To remove a member switch, right-click it, and from the pop-up menu, select 
Remove from Cluster. The switch retains its configured password when it leaves 
the cluster. For more information about setting passwords, see the “Passwords” 
section on page 5-8.
If the candidate is in a different management VLAN than the command switch, a 
message states that this candidate is unreachable, and you will not be able to add 
it to the cluster. For more information about management VLAN considerations, 
see the “Management VLAN” section on page 5-11.
For information about how to remove Catalyst 1900 or Catalyst 2820 member 
switches, refer to the Catalyst 1900 Series Installation and Configuration Guide 
or the Catalyst 2820 Series Installation and Configuration Guide.

Manager, display
