[j-nsp] MX480 SCB firmware issue

[Masood Ahmad Shah]

It could also be a hardware issue in either the referenced scb0 or back
connector. Have you tried the following:

Re-seat the scb in its slot, and then check for bent pins at this time (you
can use a flashlight)
Swap the scb0 with a spare (Or borrow one from another slot 1, 2)

Cheers,
Masood
