X440-G2-48p Stacking 10Gbe links, license error on slot2

X440-G2-48p Stacking 10Gbe links, license error on slot2

New Contributor II
Ok so I might have shot myself in the foot here but figured I post to ask...
I have a stack of three X440-G2-48p switches, and prior to stacking I foolishly installed the 10GBe license on Slot 1 and Slot 3 as we were going to use 10Gbe uplinks (now that is not the case and will use 1Gbe). Now that I have the stack created and using Ports 49/50 for stacking I get an error that 2:49 and 2:50 are not licensed.

Can I remove the license from slot 1 and slot 3? Or can I tell the system that those are for stacking?
Should I just backup my config, wipe the nodes and start over (sans the license install)?

Here is an output from show stacking-support and show stacking

The 10G licenses won't (shouldn't) cause a license mismatch error like other licenses do.
Also keep in mind that our licensing system won't allow you to swap the 10G license from one serial number to another. If you want slot 2 to have the 10G licenses, you'll need to change your configuration - either in software or physically - so that slot 2 becomes slot 3 and slot 3 becomes slot 2.

Hi Robert,

Since slot two is the "backup" it needs to have the same license as the master. Backups are the next Master in the event of a Master fail.

Removing the license should clear the error;
