If you are unable to repair a member switch, you can replace it with a different member
switch and retain the old configuration. The master stores the configuration of the member
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
command to change the serial number in the Virtual Chassis configuration
file. Substitute the serial number of the replacement member switch (on the
back of the switch) for the serial number of the member switch that was
removed.
Power off and disconnect the member switch to be replaced.

When you remove a member switch from the Virtual Chassis configuration, the master
keeps its member ID on reserve. To make that member switch's member ID available for
reassignment, issue the request virtual-chassis recycle command from the Virtual
Chassis master.
NOTE: When you add or delete members in a Virtual Chassis configuration,
internal routing changes might cause temporary traffic loss for a few seconds.
