Step 7Hold the mounting bracket and insert a 6-32 x 0.18-inch screw into each of the four corresponding holes 
(A, B, or C) and tighten.
Step 8If necessary, drill or cut a cable access hole in the ceiling tile large enough for the Ethernet and power 
cables. Pull the cables through the access hole until you have about 1 foot of cable protruding from the 
hole.
