Steps to replace a
stack member
If you need to replace a stack member, use the following steps to achieve
a smooth transition.
1. Configure the Stack ID on the replacement switch
Prepare the replacement switch by configuring it with the same stack ID as
the switch that you are replacing.
2. Configure the feature licenses
Ensure that the replacement switch is configured with the same set of
feature licenses as the existing stack members.
3. Remove the failed switch
Unplug the failed switch from the stack.
4. Install the replacement switch
Connect the stacking cables to the replacement switch and power up the
switch. It will detect that there is already an active master, and so will
come up as a stack member.
The active master will check that the new stack member has the same
software version as itself. If the software versions are different, the active
master will use the software auto-synchronization mechanism to force the
new stack member to run the same software version.
Note that if the software releases differ between the stack members
significantly, then the stack master may not be able to upgrade the new
switch automatically. If this happens, you should see a log message
indicating incompatible stack software versions, in which case you will
have to manually upgrade the new switch to the correct release.
The new switch will also receive the startup configuration from the active
master. As the replacement switch has been configured with the same
stack ID as the replaced switch, it will receive exactly the same
configuration as the replaced switch, and will operate exactly as that
switch had.
Provisioning Provisioning provides the ability to pre-configure ports that are not yet
present in a switch or in a stack.
Similarly, if you know that a switch is going to be added to a stack, you can
pre-configure the new switch in anticipation of its addition to the stack.
With provisioning, you can configure stack members and their ports even
though they are not currently physically present, and configure them ready
for future addition. This means that you can either pre-configure ports
belonging to a bay or switch that has not yet been installed, or load a
configuration that references these ports.
It is possible to provision both x610 Series switches and x600 Series
