The 4100-5115 Expansion NAC Module (XNAC) is an option board that provides three NACs in
addition to the three NACs already on the XPS. The XNAC plugs onto the XPS.
If you are not installing an XNAC, skip this section and continue on to “Step 6: Troubleshooting.”
The XNAC has three NACs, each rated at 3 A. As on the XPS, there is one status LED for each
NAC.
The XNAC mounts to the top of the XPS as shown in the instructions and Figure 13, below.
Note:
The XNAC cannot be installed on an XPS that is mounted to a 4100-2301
Expansion Bay that is used in a non-4100U/4100ES back box (a back box with PID
series 2975-91
xx
).

Figure 13. Mounting the XNAC
1.
Insert plastic standoffs (202-078) and a metal standoff (202-077) to the XPS as shown in
Figure 12.
2.
Plug J1 on the XNAC into P3 on the XPS using a header (166-549). The holes on the edges of
the XNAC should be aligned with the tops of the standoffs.
3.
Secure the XNAC to the standoffs using four screws.
4.
Connect the XNAC’s signal power harness to P1 on the XPS.
The XNAC uses the same wiring rules as TB1 on the XPS. Refer to “Step 4. XPS Field Wiring” to
wire the XNAC to notification appliances. Note that the XNAC cannot be used for auxiliary
power.
