Step 1: Connect a cable by feeding the F-connector on the back of the cable modem. Ensure the center conductor of the

75 ohm coaxial cable is inserted directly into the center of the F-connector. Secure the coaxial cable by carefully

threading the outer shell of the coaxial cable connector onto the F-connector in a clockwise direction until tight. Be

careful not to over-tighten the connector or you may damage either the connector or the cable modem.

Step 2: Connect the cable modem to a GbE Ethernet 10/100/1000/2500 Mbps Network using a RJ-45 male-terminated

Ethernet cable. This cable modem equips with four Ethernet ports, you can connect four PCs to the cable modem at the

same time if necessary.

Step 3: Connect the AC Adapter to the cable modem by inserting the barrel- shaped connector into the mating power

connector on the back of the cable modem. Exercise carefully to ensure the connectors are properly aligned prior to

Remember to use only power adapter that came with the cable modem. Other power adapters might have voltages that

are not correct for your particular cable modem. Using a power adapter with the wrong voltage can damage the cable

modem.
