[j-nsp] upgrading an antique 240

[David Kotlerewsky]

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!

Junos 17.3R3-S10
Junos 18.4R2-S5
Junos 19.3R3-S2
Junos 19.4R3-S3
