To replace a member switch, use the procedure that matches what you need to
accomplish:
•
Remove, Repair, and Reinstall the Same Switch on page 237
•
Remove a Member Switch, Replace It with a Different Switch, and Reapply the Old
Configuration on page 237
•
Remove a Member Switch and Make Its Member ID Available for Reassignment to a
Different Switch on page 238
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 for the member ID so that it can be reapplied when the member
switch (with the same base MAC address) is reconnected.
To remove, repair, and reinstall the member switch:
1. Power off and disconnect the member switch to be repaired.
2. Repair, as necessary.
3. Reconnect the switch and power it on.
Remove a Member Switch, Replace It 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
switch while retaining the previous configuration. The master stores the configuration of
the member that was removed. When you connecta 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, you can use the
replace command to change the serial number in the Virtual Chassis
configuration file. Substitute the serial number of the replacement member
switch (onthe back of the switch) forthe serial number of the member switch
that was removed.
To remove and replace a switch and reapply the old configuration:
1. Power off and disconnect the member switch to be replaced.
2. If the replacement member switchhas been previously configured, revert thatswitch’s
configuration to the factory defaults. See Reverting to the Default Factory Configuration
for the EX Series Switch for information about reverting to the factory default
configuration on an EX Series switch or Reverting to the Default Factory Configuration
for information about reverting to the factory default configuration on a QFX Series
switch.
3. If you are interconnecting a switch using a dedicated VCP, connect one VCP on the
replacement member switch to a VCP of another Virtual Chassis member switch.
