> Juniper’s KB21476 says they recommend the below Junos versions for the original boxes as of 6/1/2021. Given that you are running 14.2, you’d probably have to do a couple of interim upgrades to get to the list below. I would refer to the release notes just to be sure. Unfortunately this is not a -BP chassis with enhanced midplane connectors, so the switch card upgrade for this chassis is non-existent to the latest, but it’s still a heck of a platform!

are you sure that this SCB model (the original) is supported past junos 14?
the compatibility matrix seemed to imply SCB-E is the minimum, but that
might be due to an EoL.
