The Link light varies to indicate the current link state:
●
Valid Link – The light is green and steadily on. The MA-428 module adapter is ready to operate.
There should be no data loss.
● No Link – The Link light is not on and there should not be any data transfer.
● Unstable Link – A few of the Ethernet network interface cards (NICs) in the computer may not be
able to identify the duplex mode on the other end. Because of this limitation, auto-negotiation
does not always work and the module adapter defaults to half-duplex.
● False Link – Even though the link is established, data loss occurs.
