Performing the Installation
4. Attach the top of the antenna to the 1/4-20 threaded stud on the swivel head and tighten the nut
against the antenna.
5. Loosen the set screw on the swivel assembly, if necessary, with the Allen wrench that is provided.
6. Position the antenna to maximize the reception and tighten the set screw.
Hoffman Enclosure RS4000 Installation
Use the procedures in this section to mount the RS4000 within the Hoffman enclosure. It will be
necessary to modify the Hoffman enclosure by drilling cable pass-through holes before installing the
RS4000.
Creating Cable Pass-through Holes in the Hoffman Enclosure
To create cable pass-through holes in the Hoffman enclosure, Meru supplies a template with markings
that coincide with the placement of the Ethernet and antenna cable locations on the RS4000.
Depending on the orientation of the RS4000 installation in the Hoffman enclosure, the template is to
be used on the side of the enclosure adjacent to the RS4000 top panel, where the cables connect.
1. Open the lid of the empty Hoffman enclosure to provide unimpeded access to the enclosure sides.
2. On the outside of the empty Hoffman enclosure, locate the top center of the side where the cables
will exit.
3. Using the pattern on the supplied template, mark the center of the holes and drill a 1/2" to 1" hole
at each of the three locations specified by the template.
Mounting the RS4000 in the Hoffman Enclosure
To mount the RS4000 in the Hoffman enclosure, it is necessary to use the mounting plate that is
supplied with the RS4000 packing items. This procedure assumes the Hoffman enclosure is already
mounted at the site.
1. Remove the bracket from back side the RS4000 if it is attached by unscrewing each of the 4
knurled thumbscrews.
2. Attach the mounting plate to the back of the RS4000 with four 6-36 screws. The plate is larger
than the RS4000, and the overlap portion has screw holes that match up with the screwholes in
the Hoffman enclosure.
3. Attach the two antenna cables to the SMA antenna connectors labeled
ANT 1 and ANT 2 on the
top panel of the RS4000 (see Figure 4) by turning the cable ends clockwise until tight.
Note:
The recommended Meru installation is a vertical wall mount, which allows for unimpeded
air flow through the unit. The option to install the RS4000 within a Hoffman enclosure is left to the
customers discretion, based on site-specific factors such as protection and accessibility, etc.
Installation in the Hoffman enclosure requires drilling air vents and cable pass-through holes.
