Connect Modem to Ethernet
The Modem may be connected to a single computer or Ethernet device through the 10/100 BASE-TX Ethernet port on
the rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a speed of
10/100 Mbps only. When connecting the Modem to any Ethernet device that is capable of operating at speeds between
0~100Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port.
Use Category 5 or better twisted-pair Ethernet cable with RJ-45 connectors. The RJ-45 port on the Modem is auto MDI-
X/MDI-II meaning that is will link correctly with either MDI-II through or MDI-X crossed ports.
The rules governing Ethernet cable lengths apply to the LAN to Modem connection. Be sure that the cable connecting
the LAN to the Modem does not exceed 100 meters.
