Upgrading or Downgrading an M10i CFEB or CFEB-E

To upgrade by replacing a CFEB with a CFEB-E or 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 to downgrade from a CFEB-E to a CFEB:

1. Remove the CFEB or CFEB-E as described in Removing an M10i CFEB or CFEB-E.
2. Install the upgrade CFEB-E or downgrade CFEB as described in Installing an M10i CFEB or CFEB-E.
3. Reboot the router:
   • If the router has only one routing engine, issue the CLI command
     
     

     user@host> request system reboot
   • If the router has two routing engines (a primary routing engine and a backup routing engine), from the primary routing engine issue the following two CLI commands in immediate succession to force the router to reboot:
     
     

     user@host> request system reboot other-routing-engine
     
     

     user@host> request system reboot

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