Connecting the Cable Modem

Cable Modem 900A

  1. Connect one end of the coax cable to the cable outlet or splitter, and the other end to the Cable Modem’s Cable connector (C). Tighten the connections by hand, then tighten an additional 1/8 turn with a wrench. Note: For best performance, use high-quality RG-6 type coax cable and minimize or eliminate splitters between the cable jack and the Cable Modem.
  2. Insert the plug from the power cord into the Power connector on the Cable Modem (D) and insert the power cord into an AC outlet. The Power light on the front of the Cable Modem lights up, then flashes once.
  3. Connect one end of the yellow Ethernet cable to the yellow port on the back of the Cable Modem labeled “Ethernet 10/100/1000” (A), and the other end to the Ethernet port on a computer, hub, or broadband router.
