Figure 7-1 Flush Mounting Bracket Detail
Consideration:
• The Fusion Main Hub is shipped with #10-32 mounting screws. Another common
rack thread is #12-24. Confirm that the mounting screws match the rack’s threads.
To install the Hub in a rack:
1. Insert spring nuts into rack where needed or use existing threaded holes.
2. Place the Hub into the rack from the front.
3. Align the flange holes with the spring nuts installed in Step 1.
4. Insert the mounting screws in the appropriate positions in the rack.
5. Tighten the mounting screws.
Installing an Optional Cable Manager in the Rack
• Using the screws provided, fasten the cable manager to the rack, immediately
above or below the Main Hub.
Installing a Main Hub Using the 12” Wall-Mounted Rack (PN 4712)
Considerations:
• The rack-mounting brackets on the Fusion Main Hub must be moved to the
recessed mounting position (shown in Figure 7-2) to allow for the required 76 mm
(3 in.) rear clearance.
