Procedure 3
Installing the Option 11C Mini chassis on a wall in a horizontal position
1 Draw two vertical lines 18.5 inches apart on the plywood
backboard.
Allow for clearance on the left and right of the chassis for cables and
air flow. Refer to the equipment layout plan for measurements.
2 Draw a horizontal line on the plywood backboard.
This line indicates the vertical position of the bottom hole on the
horizontal wall shelf bracket. Refer to the equipment layout plan for
measurements.
3 Place the left shelf bracket against the plywood backboard. Place
the lower mounting hole over the intersection of the left vertical
line and the horizontal line.
Fasten the shelf bracket securely to the plywood backboard. Use four
#12 wood screws provided in the bracket kit (or other appropriate
fasteners) to fasten the shelf bracket to the backboard.
Note: Position the shelf bracket so that the two thumb screws, located
on the bottom of the bracket, face downward. Leave the screws slightly
loose, so you can adjust the brackets to the width of the chassis if
necessary.
4 Place the right shelf bracket against the plywood backboard.
Place the lower mounting hole over the intersection of the right
vertical line and the horizontal line. Fasten the shelf bracket
securely to the plywood backboard with the remaining four #12 wood
screws provided in the bracket kit (or other suitable fasteners). See
Figure 26.
Note: Make sure the shelf bracket is oriented with the two thumb
screws, located on the bottom face of the bracket, facing downwards.
Leave the screws slightly loose, so you can adjust the brackets to the
width of the chassis if necessary.
