2-164. The Ethernet card has lost its link and is not receiving a valid signal.
The G1000-4 port reporting the alarm is not receiving a valid signal from the attached Ethernet
device. The CARLOSS can be caused by an improperly connected Ethernet cable or a problem with
the signal between the Ethernet device and the G1000-4 port.
