1 Follow the process in
Removing a Unit from the Stack
on page 29 to remove the desired stack
member.
2 Follow the process in
Adding a Unit to an Operating Stack
on page 29 to add a new member to the
stack with the following exceptions:
•
Insert the new member in the same position in the stack as the one removed.
•
It is not necessary to preconfigure the unit.
If a stack member is replaced with a unit of a different model number, follow these steps:
3 Follow the process in
Removing a Unit from the Stack
on page 29 to remove the desired stack
member.
4 Remove the now-absent stack member from the configuration by issuing the
no member
command in Config Stack mode.
5 Add the new stack unit to the stack using the process described in
on page 29. 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
ensure that the stack does not get divided into two separate stacks, causing the election of a new
manager.
Renumbering Stack Members
1 If particular numbering is required, we recommend 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 command
switch oldunit-id renumber newunit-id
in Global Config mode.
3 Renumbering a non-manager unit requires a unit reset for the renumbering to take effect.
Renumbering a manager unit requires a reset of all the switches in the stack for the renumbering to
take effect.
4 If the newunit-id has been preconfigured, you may need to remove the newunit-id from the
configuration before renumbering the unit.
5 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, we recommend that all units
except the manager be powered down and added back one at a time using the procedure in
on page 29.
Using the web Interface, you can renumber a switch using the Stacking - Unit Configuration page. To
renumber a switch:
6 Select
Stacking
>
Base
>
Unit Configuration
.
7 In the
Switch ID
field, select the switch you want to renumber.
8 Click the Edit Switch ID (pencil) icon, select a new number in the drop-down list, and click
Submit
.
Moving a Manager to a Different Unit in the Stack
Use the following steps to change the stack manager from the current switch to a new switch in the
stack:
