Fusion Installation Procedures

Figure 7-2 Installing in the Recessed Mounting Position

NOTE: If wall stud spacing of 16” is not available, LGC recommends that

3/4” plywood be pre-installed to the wall. You can then attach the bracket to

the plywood using the wood screws.

2. Remove both of the rack mounting brackets from the Hub.

3. Reattach each of the rack mounting brackets to the recessed wall mount position.

4. Install the Hub in the rack using the rack mounting screws.

Installing a Fusion Main Hub Directly to the Wall

To install the Hub directly to the wall:

1. Pre-install 3/4” plywood to the wall.

2. Mount both of the rack mounting brackets using #10-32 machine screws (refer to

illustration Figure 7-3).

3. Attach the Hub to the wall so the mounting brackets are orientated at the top and

bottom of the wall mounted hub.

Use two #10 Pan Head wood screws, 1-1/2” length, to secure each bracket to the

plywood. In this orientation the enclosure fans shall face to the left.
