3.2 

Check the Ethernet cable 

If you connect a radio and the Ethernet LED does not light on the radio, there 
may be a problem with the Ethernet cable. Verify that the cable is plugged into 
the radio at one end, and to an Ethernet hub or a 10/100 Base-T Ethernet switch 
at the other end.  
 

Note: 

The RLXIB-IHN radio auto-detects the Ethernet connection type, and does not require a 

crossover cable for direct connection to a PC.
