Installation Guide

Overview

The NXA-ICSNET ICSNet Daughter Card (FG2105-10) is used to provide 
ICSNet connectivity for NI-2100 and NI-3100 units that are not already 
ICSNet-ready. 

This card is already installed within the NI-4100 NetLinx Integrated Controller, 
and the versions of both the NI-2100 and the NI-3100 that are ICSNet-Ready 
(FG2105-14 and FG2105-15, respectively). 
It is an optional accessory to both the baseline NI-2100 and NI-3100 units.
The NI-2100 (FG2105-04) can be upgraded to provide one ICSHub and two 
ICSNet ports through either a field installation of the optional NXA-ICSNET card 
or by purchasing the ICSNet-ready version (FG2105-14) directly from AMX.
The NI-3100 (FG2105-05) can also be upgraded to provide one ICSHub and two 
ICSNet ports through either a field installation of the optional NXA-ICSNET card 
or by purchasing the ICSNet-ready version (FG2105-15) directly from AMX. 

Note: The NI-2100 and NI-3100 upgrade procedures are identical.
The NXA-ICSNET comes with all required mounting hardware:

• 3 nylon screws
• 3 nylon nuts
• 3 nylon spacers

2.

Remove the chassis housing screws from both the sides and top of the 
NI-2100/3100 Controllers, as shown in FIG. 3 by using a grounded 
screwdriver. 
The NI-2100/3100 units each have six screws on the top and three on both 
sides.

• You can also remove the factory-installed mounting brackets by using a 

grounded screwdriver to remove the two sets of screws securing these 
brackets.

Carefully pull-up and remove the housing from the Controller to expose the 
internal circuit board.  

4.

Place the housing aside for later re-installation and continue with the pro-
cedures in the following sections to both remove the ICSNet cover plate 
and install the NXA-ICSNET card.

Removing the Motherboard

Outside the chassis, remove all Phoenix connectors. (FIG. 3)

2.

Inside the chassis, unplug the ribbon cable from motherboard.

3.

Outside the chassis, remove the eleven screws securing motherboard to 
chassis, and carefully remove the motherboard. (FIG. 3)

Installing the NXA-ICSNet Daughter Card

1.

Working on a grounded surface, insert the 3 nylon screws through the 
motherboard and thread on the 3 nylon spacers until they are seated firmly 
against the motherboard (FIG. 4).

2.

Orient the NXA-ICSNET card such that the three screws in the mother-
board align with the three mounting holes in the ICSNET card. 

3.

Gently lower the NXA-ICSNET card with the nylon screws going through 
the mounting holes, until the card connector is fully engaged, and the 
NXA-ICSNET card is seated on the nylon spacers.

4.

Thread on the other 3 nylon spacers until they are seated firmly against the 
NXA-ICSNET card. Securely tighten; however, do not over tighten. (FIG. 5)
