Remove A Switch From A Stack - NETGEAR M4200 Software Administration Manual

2. Preconfigure any new switches.
3. Power off all new switches that must join the stack.
CAUTION:
If you cable one or more powered-on switches to the stack, the existing
stack and the new switches assume that two stacks are merging. They
elect a single, new stack master, and you cannot specify which switch
becomes the new master. All stack members assume the configuration
that is based on the new stack master. Stack members change their stack
member numbers to the lowest available numbers.
4. Install the new switches in the rack.
This procedure assumes installation below the bottom-most switch, or above the
top-most switch.
5. Disconnect the redundant stack cable that connects the last switch in the stack to the first
switch in the stack at the position in the ring where you intend to insert the new switch.
Note: If you want to merge an operational stack into the this stack, add the
switches as a group by unplugging one stacking cable in the operational
stack and physically connecting all unpowered units at that point.
6. Connect this cable to the new switch, following the established order of stack-up to
stack-down connections.
7. Power up the new switches one by one.
8. Verify, by monitoring the master switch console port, that the new switch joins the stack by
issuing the show switch command. The new switch joins as a member (never as master;
the existing master of the stack must not change).
9. If the firmware version of the newly added member is not the same as the existing stack,
update the firmware (see
