Compliance
|
The 1200 series access point complies with UL 2043 for products installed in a building's environmental air handling spaces, such as above suspended ceilings.
Caution Only the fiber-optic power injector (AIR-PWRINJ-FIB) has been tested to UL 2043 for operation in a building's environmental air space; no other power injectors or power modules have been tested to UL 2043 and they should not be placed in a building's environmental air space, such as above suspended ceilings.
Note If you plan to mount the access point in environmental air space using a 802.11a radio, Cisco recommends that you mount the access point horizontally with its antennas pointing down. Doing so results in the access point complying with regulatory requirements for environmental air space with an 802.11a radio installed.
