215148-D
To replace a failed unit in a stack configuration, and preserve configuration
information:
1 Ensure that you have uploaded the stack configuration file to the TFTP server
using the management system before a unit fails.
2 Obtain the new BayStack switch you want to insert into the stack to replace
the unit that failed.
3 Ensure that the new switch you will be inserting is set to factory default
values. You will be configuring this new unit in standalone mode, before
inserting it into the stack.
4 Download the part of the configuration file corresponding to the unit you are
replacing from the TFTP server to the standalone BayStack switch unit. (The
standalone unit extracts the relevant configuration information.)
With the management system you are using (connected to the standalone
replacement unit), you will specify the unit you are replacing. The standalone
switch resets, and reboots with the correct configuration for the stack.
5 In the stack, using the management system, specify the unit number you want
to replace.
6 Physically replace the failed unit in the stack with the newly configured
switch and complete the cabling.
7 Turn on the replaced unit.
The new unit joins the stack as the replaced unit and it comes up
appropriately, without resetting the stack.
Note: The new unit must be running the identical software and firmware
version as the unit you are replacing. You must replace a BayStack
470-48T switch with a BayStack 470-48T switch and replace a BayStack
470-24T switch with a BayStack 470-24T switch.
