Procedure 3

Installing the Option 11C Mini chassis on a wall in a horizontal position

1Draw 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.

2Draw 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.

3Place 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.

4Place 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 appropriate fasteners). See Figure 27.

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.
