This equipment needs to be grounded. Use a green and yellow 12 to 14 AWG ground wire to connect the host to earth ground during normal use. Statement 242

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Read the wall-mounting instructions carefully before beginning installation. Failure to use the correct hardware or to follow the correct procedures could result in a hazardous situation to people and damage to the system. Statement 378

•Do not stack anything on top of the router.

•Do not cover or obstruct the router vents located on both sides and top of the routers; otherwise, overheating could occur and cause damage to the router.

•Place router in ventilated area to avoid local air heating.

Do not cover or obstruct the router vents located on both sides of the router; otherwise, overheating could occur and cause damage to the router.

Do not place anything on top of the router that weighs more than 10 pounds (4.5 kilograms), and do not stack routers on a desktop. Excessive weight on top of the router could damage the chassis.

Do not install the router or power supplies next to a heat source of any kind, including heating vents.

The top surface of the router is hot since heat is dissipated through the top. Do not keep any object in direct contact with the surface for a prolonged period.

Installing Antennas

The Cisco 890 series wireless routers have three reverse-polarity threaded Neill-Concelman (RP-TNC) connectors on the back panel. The antennas that are shipped with the router are dual-band 2.4-GHz to 5-GHz omnidirectional dipole antennas.
