Connecting the Cisco Cable Modem HWIC
To connect the Cisco cable modem HWIC to the router, follow these steps:
Step 1 Verify that the router is powered off.
Step 2 Insert the Cisco cable modem HWIC in the HWIC slot of the Cisco router.
Note For specific information regarding WIC/HWIC support for the routers that support Cisco cable
modem HWICs, see the hardware installation documentation for your router at www.cisco.com.
Step 3 Locate the RF coaxial cable coming from the coaxial cable CATV wall outlet.
Step 4 Install a cable splitter/directional coupler, if needed, to separate signals for TV and computer usage. If
necessary, also install a high-pass filter to prevent interference between the TV and computer signals.
Step 5 Connect the RF coaxial cable to the Cisco cable modem HWIC F-connector. Hand-tighten the connector,
making sure that it is finger tight; then give it a 1/6-turn with a wrench. See Figure 137
