The IntelliJack is available in three connector types: -LC (3CRNJ240FXLCTAA-75), 
-SC (3CRNJ240FXSCTAA-75), and -ST (3CRNJ240FXSTTAA-75). Before you begin 
the installation, familiarize yourself with the following items, which are included 
with the IntelliJack: 

• NJ240FX IntelliJack.

• Mounting plate

• Plastic cable housing tray

• Power cord

• Three screws

• Compact disc containing

n

User Guide and additional informational documents.

n

Configuration Manager software.

Because the depth of some wall and cubicle openings differ, observe the following 
requirements and recommendations before installing the IntelliJack:

• Ensure there is enough volume in the wall opening to accommodate fiber 

cables.

• Ensure there is clearance around the unit for proper cooling.

• The NJ240FX has been designed for installation into wall or cubicle openings 

that conform to NEMA standards.

• Make sure the distance between the back of the IntelliJack and the inside of 

the wall or cubicle opening is at least 25mm to maintain an acceptable bend 
radius on the cable.

• To ensure proper horizontal cabling functionality, adhere to the following 

standards during installation:

n

ANSI/TIA/EIA-568 
Commercial Building Telecommunications Cabling Standard

n

ANSI/TIA/EIA-569
Commercial Building Standard for Telecommunications Pathways and 
Spaces

The network cabling at your site (from the wiring closet to the wall or cubicle 
opening) may already be installed. If it is not, install the cabling following these 
general guidelines.
