Ethernet
Ethernet devices (10Base-T/100Base-T/1000Base-T) are connected to the SmartNode over a cable with RJ-45
plugs. The Ethernet port on the SN4940 is Auto-MDX and uses any straight or crossover cable to connect to
hubs, switches, PCs or other devices.

The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
