Ensure that the card is securely connected.
Communication Failure
* Is the UTP/fiber cable connected to the correct port?
* Are the SFP modules complied with the same standard each other?
* Is the fiber cable correct the fiber mode (single or multi)?
* Try to disable "Power Saving" or EEE (Energy Efficient Ethernet; IEEE802.3az)
function at target port.
* Are the communication speed and mode settings correct?
If the port mode settings cannot be properly obtained, the Switching Hub oper-
ates in half-duplex mode. Check the auto negotiation setting again.
Do not fix the speed/duplex mode of the connected terminal to full-duplex mode.
