Remove, Repair, and Reinstall the Same Switch
If you need to repair a member switch, you can remove it from the Virtual Chassis
configuration without disrupting network service for the other members. The master
stores the configuration of the member ID so that it can be reapplied when the member
switch (with the same base MAC address) is reconnected.
1. Power off and disconnect the member switch to be repaired.
2. Repair,as necessary.
3. Reconnect and power on the member switch.
Remove a Member Switch, Replace with a Different Switch, and Reapply the Old Configuration
If you are unable to repair a member switch, you can replace it with a different member
switchandretaintheoldconfiguration.Themasterstorestheconfigurationofthemember
that was removed. When you connect a different member switch, the master assigns a
new member ID. But the old configuration is still stored under the previous member ID
of the previous member switch.
NOTE: If you have used a preprovisioned configuration, use the replace command to
change the serial number in the Virtual Chassis configuration file. Substitutethe serial
number of the replacement member switch (on the back of the switch) for the serial
number of the member switch that was removed.
1. Power off and disconnect the member switch to be replaced.
2. Ifthereplacementmemberswitchhasbeenpreviouslyconfigured,revertthatswitch’s
configuration to the factory defaults. See Reverting to the Default Factory
Configuration for the EX Series Switch.
