This chapter describes the proper steps for connecting your cable modem. Please be sure to follow
the steps in the sequence outlined below. Failure to do so could result in improper operation or failure
of your cable modem.
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.
Step2: Connect the cable modem to an IEEE 802.3 10BaseT / 802.3u 100Base-TX Network using a
RJ-45 male-terminated Ethernet cable. This cable modem equips with one Ethernet port.

Step 3: Connect the telephone sets to TEL1 and TEL2. Use RJ-11 telephone line to connect
TEL1/TEL2 port on the cable modem and telephone socket on telephone.
Step 4: 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 insertion and ensure the two connectors engage
completely. The cable modem is shipped with an AC adapter. 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.
