Choose a location on the backboard that is level and leaves enough space on the sides (23 cm
or 9 in.) to insert and remove the media bay modules (MBMs).
4 Mark the location of the wall-mount bracket holes on the plywood backboard.
a
Use the wall-mount bracket as a template.
b Use a bubble-level to check that the wall-mount bracket is level with respect to the
plywood backboard.
5
Install four #10 x 2.5 cm (#10 x 1 in.) round-head wood screws in the backboard.
a Do not tighten the screw heads against the backboard. Leave approximately 0.5 cm (0.25
in.) of the screw exposed from the backboard.
b Perform a trial installation of the wall-mount bracket on the plywood backboard. Ensure
the wood screw heads seat in the wall-mount bracket slots. If the wood screws are too
tight, loosen until the screw heads fit fully in the slots.
c Ensure that the wall-mount bracket is level with respect to the plywood backboard.
d Remove the wall-mount bracket.
6
Align the screw holes on one side of the BCM main unit with the wall-mount bracket.
Note: The bracket suspends the BCM main unit on the wall. Consider the direction you
want the media bay modules to face, left or right, when you choose the side on which to
install the bracket.
7
Fasten the wall-mount brackets securely to the BCM main unit using the screws provided.
Refer to Figure 58
Caution: Use only the screws supplied with the wall-mount bracket kit
