Ethernet Testing
If the Ethernet link is out or has errors:
•
As this board will only work with Gigabit Ethernet traffic, verify that the devices at both
ends of the link are indeed Gigabit Ethernet devices.
•
Verify that the Ethernet devices at both ends of the link are powered up.
•
Verify that both of the dual LEDS at J4 and J7 are lit to confirm Ethernet activity at the
RJ-45 connector.
•
Attempt to PING from one device to the other.
•
If the channel is still not operating correctly, first check the field wiring. If the wiring
appears correct, then first replace the subsea Gigabit Ethernet board with a spare and
check the link again. If the problem is still there, replace the surface Gigabit Ethernet
board, with a spare and check the link again.
