Check your logs - there should be some reasons given for the alarm.
We recently saw this and the box had logged a series of CRC errors
from that chip.  JTAC issued an RMA.  It seems there's an extremely
rare software issue that can sometimes log CRC errors on the MX
SCB, but that in the vast majority of cases, it just means that the
board is flaky.
