Troubleshooting
Self-diagnostic Test Procedure
1. Two Ethernet extenders are connected, as a pair, 
using BNC connectors over coaxial cable.
2. One Ethernet extender is configured as a local 
unit. The setting mode switch on the rear panel of this 
Ethernet extender is set to Loc (local mode), and is 
located at the local end of the Ethernet extension.
3. The other Ethernet extender is configured as the
remote unit. The setting mode switch on the rear 
panel of this Ethernet extender is set to Rmt (remote 
mode), and is located at the remote end of the Ethernet 
extension.
4. Supplied AC to DC power adaptors are connected 
to the receptacles on the rear panel of both Ethernet 
extenders. Both adapters are plugged into standard 
AC outlet sockets.
5. LED 5 on the top panel of both Ethernet extenders 
lights up in an amber or green color, showing 
that both Ethernet extenders are connected and 
have negotiated best performance for symmetrical 
transmission.
