Mounting Above A Suspended Ceiling - Cisco 521 Manual

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.
