Installation Guide

Make sure the distance between the back of the Network Jack and the inside of the wall or cubicle opening is at least 1.5 inches (3 inches is recommended).

NOTE: Some cubicle openings have a depth of 1.2 inches. In this case, install the Network Jack using the extension ring (available for purchase separately; see “Obtaining Optional Components” on page 7) to obtain the minimum 1.5-inch depth.

If installing into a wall junction box, make sure there is enough space between the back of the Network Jack and the inside of the junction box to maintain an acceptable bend radius on the cable. If you encounter interference or need additional clearance between the Network Jack and where it sits inside the junction box, use the extension ring.

To ensure proper horizontal cabling functionality, adhere to the following network cabling standards during installation:

ANSI/TIA/EIA-568
