Removing a Unit from the Stack
Use the following steps to remove a switch from the stack:
1 Make sure the redundant stack connection is in place and functional. All stack members should be
connected in a logical ring.
2 Power down the unit to be removed.
3 Disconnect the stacking cables
4 If the unit is not to be replaced, reconnect the stack cable from the stack member above to the stack
member below the unit being removed.
5 Remove the unit from the rack.
6 If desired, remove the unit from the configuration by issuing the command
no member unit-id
in Stack mode.
Using the web Interface, you can remove a member of the stack by selecting

Adding a Unit to an Operating Stack
Use the following steps to add a switch to a stack of switches while the stack is running:
1 Make sure that the redundant stack link is in place and functional. All stack members should be
connected in a logical ring.
2 Preconfigure the new unit, if desired.
3 Install the new unit in the rack (assumes installation below the bottom-most unit, or above the top-
most unit).
4 Disconnect the redundant stack cable that connects the last unit in the stack back up to the first unit
in the stack at the new position in the ring where the new unit is to be inserted.
5 Connect this cable to the new unit, following the established order of connections. In other words,
use the redundant stack cable to connect from the first box in the stack to the last.
6 Power up the new unit. Verify, by monitoring the manager unit console port, that the new unit
successfully joins the stack by using the
show switch
command in EXEC mode. The new unit
should always join as a "member" (never as manager; the existing manager of the stack should not
change).
7 If the 200 Series software version of the newly added member is not the same as the existing stack,
update the software image.
Adding a powered-up standalone unit to an operational stack is similar to merging two operational
stacks where the standalone unit is a stack of one unit. See
Merging Two Operational Stacks
31 for more details.

Replacing the Stack Member with a New Unit
There are two options here. If a stack member of a certain model number is replaced with another unit
of the same model, follow these steps:
