Upgrading and Downgrading the CFEB and CFEB-E

To upgrade by replacing a CFEB with a CFEB-E or to downgrade by replacing a CFEB-E with a CFEB requires a system reboot after swapping the CFEB devices.

To upgrade from a CFEB to a CFEB-E or downgrade from a CFEB-E to a CFEB:

1. Remove the CFEB or CFEB-E as described in Removing the M7i CFEB and CFEB-E.
2. Install the upgrade CFEB-E or downgrade CFEB as described in Installing the M7i CFEB and CFEB-E.
3. Reboot the router by issuing the following CLI command:

After the reboot, the router recognizes the new CFEB or CFEB-E.
