NCU Controller Second Ethernet Port Connection (if IB4 board furnished)
Your system may be furnished with an IB4 board connected to the NCU backplane via a factory furnished and
connected cable. The IB4 board provides a second Ethernet port. The Ethernet port located on the NCU
Controller’s front panel can ONLY be used to connect a computer directly to the NCU. The Ethernet port
located on the IB4 board can be used to connect the NCU to your Local Area Network (LAN).
NOTE!
If your system has an IB4 board, DO NOT connect your Local Area Network (LAN) to the NCU
front Ethernet port.
