4. Attach the mount cradle to the T-rail clips using the mount cradle holes (marked with a "T").
Tip: Pre-assemble rubber spacers and screws to the mount cradle. The mount cradle can then be held with one
hand while the other hand holds a screwdriver. If mounting your MR42E to a dropped ceiling, skip to the "Power
the MR42E" section.
Electrical Junction Box Mount Using mount cradle
The MR42E can be mounted to a 4" square cable junction box, a 3.5 or 4" round cable junction box, or various
U.S. and European outlet boxes (mounting screws are not included).
Using appropriate mounting hardware for your specific type of junction box, attach the mount cradle to the
junction box.
Power the MR42E
If mounting to an electrical junction box, feed the Ethernet cable through the cable access hole in the mount cradle. If
mounting to a wall or ceiling, the Ethernet cable will feed from behind the MR42E. The
of this document lists the different powering options and their unique characteristics.
Mount the MR42E
Attach the MR42E to the Mount Cradle
(This section applies to wall and/or solid ceiling, drop ceiling or electrical junction box mount
where you have already installed the mount cradle.)
The MR42E attaches to the mount cradle with two tabs on the cradle that insert into the MR42E, and is secured to the
cradle using one screw.
