Replacing a stack unit
Note: Use only the console interface, command line interface, or
Web-based management system to replace or insert units in the stack.
To replace a failed stack unit or insert a new unit into a stack, follow this
procedure:
Step
Action
1
Upload a copy of the stack configuration file to a TFTP server.
Since unit failure is not a predictable situation, it is suggested that
the stack configuration file is backed up regularly to a TFTP server.
2
Obtain the new switch.
Ensure that the new switch is set to factory default values. This
new unit will be configured in standalone mode before inserting it
into the stack.
3
Download the configuration file to the new unit.
Download the stack configuration file produced in step 1. The new
unit will extract the relevant configuration information.
4
Set the unit number.
After the configuration file has been downloaded to the new unit,
specify the stack unit that this new unit will replace. The switch will
reboot with the stack configuration information.
5
Physically insert the new unit.
Turn off the new unit and physically replace the failed unit in the
stack. Complete the cabling to attach the new unit to the stack and
turn on the new unit.
—End—
If the base unit is being replaced, remember that the stack will have elected
a temporary base unit. The new unit will not automatically assume the base
unit status. Configure the new unit as the base unit using either the Unit
Select switch or UI button and reset the stack to make the new unit the
base unit.
