MAX HD2 LTEA IP67 LAN port dead

I have an older MAX HD2 LTEA IP67 that suddenly the LAN port is dead. I have tried all the internal lan ports and none of them will link. Has anyone seen this and is there a way to wake it up or is it toast? This unit has been sitting in an office and has not been subjected to any abuse, just been sitting in a cabinet acting as an office router.

Thanks in advance!
