Mounting Above a Suspended Ceiling

The access point mounting bracket is designed to be integrated into the T-rail

grid above the tiles of a suspended ceiling. The access point uses a T-bar box

hanger (not supplied) such as the Erico Caddy 512 or B-Line BA12 and

should be oriented just above the top surface of a standard 5/8-in. (1.59-cm)

ceiling tile. You may need to modify a thicker tile to allow room for the access

point.

Caution

Only the fiber-optic power injector (AIR-PWRINJ-FIB) has

been tested to UL 2043 operation in a building's environmental

air space; the AIR-PWRINJ3 power injector and the power

model are not tested to UL 2043 and should not be placed in a

building's environmental air space.

Caution

Cisco does not sell Ethernet cable rated for use in a building

environmental air space. You must obtain special Ethernet cable

with the appropriate rating.
