Completing the EX9200-SF3 Upgrade | 235
If you are upgrading to the EX9200-SF3 from an older SF module, the Routing Engine must be upgraded
to the first supported Junos release for the EX9200-SF3 (20.3.R1) before you install it in the EX9200-
SF3. Also, we recommend that you update the recovery snapshot with the 20.3R1 or later image before
you begin the upgrade. If the Routing Engine fails to boot from the primary image, it will attempt to boot
from the recovery image. Since the older recovery image does not support the EX9200-SF3, the Routing
Engine will crash if it attempts to boot from the old recovery image.
CAUTION: If you plug the Routing Engine into the EX9200-SF3 without first upgrading
Junos to 20.3R1 or later, Junos might crash and go to a db prompt. Should this occur,
you'll need to recover the router by copying the Junos software image for the 20.3R1 or
later release and then booting from the USB drive to install 20.3R1 Junos on the
EX9200-SF3. The USB install will wipe out the router configuration and all user files on
the Routing Engine.
