Connecting Devices to 

the NJ240FX

Once the power source and the data source have been verified in good working 

order and the IntelliJack has been installed and mounted, connect your 

networking devices (such as computers, printers, IP phones, cameras, etc.) to the 

IntelliJack.

The IntelliJack has two ways to connect devices:

1 RJ-45 Personal Area Network (PAN) Ports — any of the four switched ports on the 

bottom of the IntelliJack. All ports feature 10/100 Mbps auto-negotiation, which 

configures the NJ240FX IntelliJack for 10 Mbps or 100 Mbps connections automatically.

2 Pass-through port—a single pass-through port is provided that allows an additional 

device to be connected to a separate network segment through the same IntelliJack. 

The data or voice traffic that travels through the pass-through port, passes through 

the IntelliJack without being switched.

NOTE: An access hole is provided for installations that require the supplied AC 

power cord to be routed back into the NEMA box.  Place the AC power cord 

between the metal and plastic housing cable tray and route through the lower 

rectangular opening in the metal mounting plate.  Adjust cable for desired loop 

length before securing in place.
