[Mikrotik] Can't get fiber to work on CCR1036-12G-4S

We have a CCR with a fiber connection.  Once I got the proper module for 
it, no issues.  Taking the one out of the 2011 and putting it in the CCR 
did not work.  I don't have part numbers handy, but that link has been 
up over 132 days without an issue.
