brackets, as shown in Figure 6.
Remove the mounting frame from the wall and drill
pilot holes for each of the marked screw locations.
Before attempting to fasten the mounting frame to the
wall, insert a screw into the top pilot hole oneitherthe
left or right side. Partially thread the screw into the
hole, leaving the screw head approximately 1/4” from
the surface.
Hold themounting frame against the wall whileresting
the cutout of the bracket onthe installed screw.Align

the screws to fasten the lug to the mounting frame.
The example in Figure 7 illustrates the frame
positioned with grounding screws facing downward.
Connect a ground wire of appropriate gauge to the
ground lug, and attach the other end of the wire to a
bonded ground point, per local procedures for network
equipment.
C. Equipment Installation

carefully sliding the chassis through the front of the
WR-15U and aligning chassis mounting ears with the
threaded holes in the rails of theWR-15U frame.
Insert and tighten #12-24 machine screws (customer
provided)on each side of the chassis. An example of
a fully populated wall rack is shown in Figure 2.

One or two side plates (Model SPL-4H) can be installed
on either side of the WR-15U chassis for cable slack
management. The SPL-4H provides two split and
adjustable take-up reels, as illustrated inFigure 5.
To install and use the SPL-4H side plate, refer to Figure

into the openings onthe side of the WR-15U, toward
the rear of the mounting.
Align the wide tabs at the front edge of the SPL-4H
with the threaded holeson the side of theWR-15U
frame. Use the two (2) included #10-32 x 3/8” screws
to securely fasten the side plate to theframe.
Carefully wrap cables around the take-up reels to
reduce slack as needed. Example routing is shown in
Figure11. Alternate mounting holesare included on
the side plate for repositioning the half-reels, if desired.
