DOCSIS 1.0/ 1.1 Equivalent Cable Modem
Chapter 3 Hardware Installation
This chapter describes the proper steps for connecting your new 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 DOCSIS 1.0/1.1 equivalent cable feed to the F-connector on the back of the cable modem as illustrated in Figure 1. Ensure that 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.
NOTE: To speed up the initial cable modem registration process, the coaxial cable should be connected to the modem prior to the power connector.

Step 2:
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 as illustrated in Figure 2. 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. The cable modem power input requires 12 VDC input with minimum 1000 mA current. The +12 V is on the center connector, and ground is on the outer connector.
