How to Change a Switch Unit ID Value in a Dell Networking N2000, N3000 or N4000 Series Switch

There are three common scenarios for wanting to change this value:
 

1. When N-Series switches are removed from a stacking environment, the Unit ID is persistent.  This is cosmetic and will not affect performance, but users wanting to reset to factory will need to also reassign the member unit ID. 
2. When a switch is replaced, and the replacement needs to become a specific member to acquire the correct configuration from the primary stack switch.
3. When pre-staging equipment and the configuration is completed prior to the stack being created.

Using the web interface to renumber and remove a switch member:

Open the Dell OpenManage Switch Administrator web interface by entering the IP address of the switch in your web browser. Expanding the directories can be done by clicking on the title of each directory, clicking on the + symbol to each category’s title, or clicking directly on each of the options within the main window.
 

1. In the left window, navigate to the Unit Configuration page through:  System > Stack Management > Unit Configuration.
2. Within the Switch ID field, use the drop down to select the switch member to be changed.
3. Click on Apply Changes.
4. Select the box at the bottom of the main window Remove Switch.
5. Within the Switch ID field, use the drop down to select the previous Switch ID to be removed.
6. Select the box Remove Switch and click on Apply Changes.

Using the command line interface to renumber and remove a switch member:
 

1. config> enable
2. config#config
3. console(config)# switch <existing ID> renumber <new ID>
4. console(config)#stack

console(config-stack)#no member <ID to be removed>
