I have not tested this particular device myself...

You can use continuety test for testing Ethertnet connections. 

Take the transmitting and receiving pairs. In normal Ethernet 
connection there is a transformer coils (pretty low resistance) 
connected to transmitting and receiving pairs on both ends 
of connection. You could use a multimeter to check this 
continuety. I have used this several times for testing purposes. 

Low resistance between two wires on the pair tells there is 
something attached on those lines on the other end of the cable 
(or cable has been damaged and shorted in the middle).
