Install the AP400
Mount AP400 Above a Suspended Ceiling (Plenum)
Use the optional T-bar box hanger mounting kit to mount the AP400 above suspended ceiling T-rails
(see
). The installation attaches the T-bar box hanger to the ceiling rails and then the AP400
attaches to the T-bar box hanger. Note that an AP400 mounted above the ceiling has about 2-3 dBm
less RF coverage than an AP400 mounted under the ceiling.

The AP400 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 may need to modify thicker tiles to support this installation.
To mount an AP400 above the ceiling with the optional T-bar kit, follow these steps:
1.
Determine the location on the ceiling rails where the AP will be mounted and remove the ceiling
tile.
2.
Unpack the T-bar hanger kit and attach the legs to the main support.
3.
Attach the square bracket to the underside of the main support bar using the screws provided.
Warning!
When installed in air-handling spaces, such as above a suspended ceiling,
power the AP400 only with a PoE, not a power supply.
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). 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.
