Factory reset of Fabric Interconnect

After I reset the FI’s password the next thing I did, was do a factory reset of FI because I didn’t want to use the old configuration. So, I decided to remove all configurations and start fresh :) Be careful doing it as it will erase everything including all the IP details.

To reset the FI we just need to run a few commands and it’s a pretty easy task.

Connect to the console port or the SSH into the Fabric interconnect, login to FI and then you are in :) . Run the first command to connect to the local-mgmt.

Next command will erase the configuration of FI and then system will reboot.

The system is going down for reboot NOW!

After reboot, the Fabric Interconnect will be ready for the fresh configuration. Just remember that the console cable is required to configure it for the first time.
