Fusion Wideband Installation Procedures

7-12 InterReach Fusion Wideband Installation, Operation, and Reference Manual

CONFIDENTIAL D-620616-0-20 Rev E

Figure 7-1 Flush Mounting Bracket Detail

Consideration:

• The Fusion Wideband 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.
