NETGEAR 7000 Series Managed Switch Administration Guide Version 7.2

Add the new stack unit to the stack using the process described in section “Adding a Unit to an Operating Stack”. The unit can be inserted into the same position as the unit just removed, or the unit can be inserted at the bottom of the stack. In either case, make sure all stack cables are connected with the exception of the cable at the position where the new unit is to be inserted to insure that the stack does not get divided into two separate stacks, causing the election of a new master.

Renumbering Stack Members

1.If particular numbering is required, it is recommended that stack members be assigned specific numbers when they are first installed and configured in the stack, if possible.

2.If the desired stack unit number for a particular unit is unused, a unit can be renumbered simply by using the switch <oldunit-id> renumber <newunit-id> CLI command. This command is found in global config mode.

3.If the newunit-id has been preconfigured, you may need to remove the newunit-id from the configuration before renumbering the unit.

4.If reassignment of multiple existing stack unit numbers is necessary, there are a number of implications in terms of mismatching of configuration. In this case, it is recommended that all units except the master be powered down and added back one at a time using the procedure in Section “Adding a Unit to an Operating Stack”.

Moving a Master to a Different Unit in the Stack

1.Using the movemanagement command, move the master to the desired unit number. The operation may take between 30 seconds and 3 minutes depending on the stack size and configuration. The command is movemanagement <fromunit-id> <tounit-id>

2.Make sure that you can log in on the console attached to the new master. Use the show switch command to verify that all units rejoined the stack.

3.It is recommended that the stack be reset with the reload command after moving the master.

Removing a Master Unit from an Operating Stack

1.First, move the designated master to a different unit in the stack using “Moving a Master to a Different Unit in the Stack”.

2.Second, using “Removing a Unit from the Stack”, remove the unit from the stack.
