Basically you just need to use the first five steps of the article.
1. Create a configuration backup and copy the backup off the switch via TFTP: show config outfile configs/filename.cfg
copy configs/filename.cfg tftp:///filename.cfg
2. If there are more than two units in the stack, a closed loop stacking connection (stack cable from top unit to bottom unit for redundancy) may be necessary to ensure switches above and below the switch being removed can still communicate with each other
3. Disconnect power cable from the unit to be removed from the stack, then disconnect the stack cables (Note: If the manager unit is being removed, a disruption to the other stack members will occur until new manager is chosen)
4. To clear the configuration from the stack for the disconnected switch, issue the command: clear switch member
5. Reconnect the running units back together in the same matter with the stack cables (up to down, or down to up ports)
