Where Is the Best Location for My Residential Gateway?

The ideal location for your residential gateway is where it has access to outlets and

other devices. Think about the layout of your home or office, and consult with your

service provider to select the best location for your residential gateway. Read this

user guide thoroughly before you decide where to place your residential gateway.

Consider these recommendations:



Choose a location close to your computer if you will also use the residential

gateway for high-speed Internet service.



Choose a location that is near an existing RF coaxial connection to eliminate the

need for an additional RF coaxial outlet.



Choose a location that is relatively protected from accidental disturbance or

harm, such as a closet, basement, or other protected area.



Choose a location so that there is plenty of room to guide the cables away from

the residential gateway without straining or crimping them.



Choose a location that allows adequate ventilation around the residential

gateway.

Leave sufficient clearance between the bottom of the residential gateway and any

flooring or shelving underneath to allow access to cabling.
