Mounting the USB HUB4
The USB HUB4 can be mounted to a wall, on a rack, in furniture, or in an Extron
architectural product, such as a cable cubby or HSA.
Wall or furniture mounting
The HUB4 can be attached to a wall, podium, or other flat surface with either a
stud-mounted wall box or with a wall mounting bracket (such as the Extron MR or
MR D series). Both types of installations require a double-spaced AAP or MAAP
mounting frame (such as the AAP 102 or the CPM101).
Installing the wall box or mounting bracket
Use a one-gang sized wall box or mounting bracket for the HUB4 MAAP or a two-
gang box or bracket for the AAP model. Install cables into the wall, furniture, or
conduits before installing the wall box or bracket.
If using a wall box, the mounting site must be deep enough for both the box and
the cables. The box should be at least 2.5 inches (6.4 cm) deep.
1. Place the wall box or mounting bracket against the installation surface and
mark guidelines for the opening on the wall or furniture.
2. Cut out the material from within the marked area.
3. Insert the wall box or bracket to check the opening’s size and fit. Enlarge or
smooth the edges of the opening as needed.
4. If using a wall box, feed the cables through the box’s punched out holes and
secure the cable clamps to provide strain relief.
5. Exposed cable shields (braids or foil) are potential sources of short circuits.
Trim back and/or insulate shields with heat shrink.

W To prevent short circuits, cut back the outer foil shield to the point where
the cable exits the cable clamp. Both braided and foil shields should be
connected to an equipment ground at the other end of the cable.
