Installing the Access Points
Warning! The AP200 with the metal enclosure exposed meets the requirements for
fire resistance and low smoke-generating characteristics required by Section 300-
22(C) of the National Electrical Code (NEC) for installation in a building's
environmental air space. You must remove the plastic enclosure to reveal the
plenum-rated AP200 metal case for installations above a suspended ceiling.
Additionally, you must use Ethernet cable that meets the requirements for operating
in plenums and environmental air space (in accordance with Section 300-22(C) of the
NEC).
Warning! Any Fast Ethernet (FE) cables installed in air-handling spaces should be
suitable under NEC Article 800.50 and marked accordingly for use in plenums and air-
handling spaces with regard to smoke propagation, such as CL2-P, CL3-P, MPP (Multi
Purpose Plenum), or CMP (Communications Plenum).
