4.2.3.5 Plenum Mount (Above Drop Ceiling)

The MR16 can be mounted to the T-bar grid above the tiles of a drop ceiling using a 3rd party T-bar box hanger

(not included). The Erico Caddy 512A is recommended and is used in installation instruction illustrations.

Note: a UL2043-rated Ethernet cable should be used for a plenum installation.

1. Adjust the height of the T-bar box hanger crossbar to make sure there is adequate clearance between

the access point and the top of the ceiling tiles. Tighten the height adjusting screws.

2. Attach the bracket mounting clip (included with T-bar box hanger) to the center of the T-bar box hanger crossbar.

3. Attach the MR16 mount plate to the access point mounting bracket using a 6-32 screw and washer (not included

with T-bar box hanger) and the Above Drop Ceiling (Box Hanger) hole in the mount plate (reference Mounting

Template).

4. Connect Ethernet cable to Ethernet port on MR16 and route cable through cable slot.

5. Install MR16 on mount plate.

6. Securely attach the clips on either side of the T-bar box hanger to the suspended ceiling grid T-rails.

7. Connect a grounding wire (not included with T-bar box hanger) to the grounding hole in the bracket mounting clip

and to metal building structure. A grounding wire is required to comply with the U.S. National Electric Safety Code.
