Power Connector

The NI-9154 has a power connector to which you can connect a primary and secondary power supply. The following table shows the pinout for the power connector.

Table 1. Power Connector Pinout
Pinout Pin Description
1378 V1 Primary power input
C Common
V2 Secondary power input
C Common
Caution The C terminals are internally connected to each other, but are not connected to chassis ground. This isolation is intended to prevent ground loops and does not meet UL ratings for safety isolation. You can connect the C terminals to chassis ground externally. Refer to the specifications on ni.com/manuals for information about the power supply input range and maximum voltage from terminal to chassis ground.

If you apply power to both the V1 and V2 inputs, the NI-9154 operates from the V1 input. If the input voltage to V1 is insufficient, the NI-9154 operates from the V2 input.

The NI-9154 has reverse-voltage protection.

The following NI power supplies and accessories are available for the NI-9154.

MXI Express Port

You can use the MXI Express port on the NI-9154 to connect to a MXI Express chassis. Complete the following steps to connect one or more NI-9154 to a MXI Express device.
  1. Make sure the MXI Express device is configured and powered off.
  2. Make sure the NI-9154 is powered off.
  3. Connect the NI-9154 to the MXI Express device using a x1 cable.
  4. Power on the MXI Express device.
  5. Power on the NI-9154.

    The MXI Express LINK LED on the front panel of the NI-9154 lights green when communication is established. The LINK LED lights yellow when communication is broken or no cable is connected.

    Note The NI-9154 may not detect MXI Express devices connected while the NI-9154 is powered on.

    The following table shows the MXI Express cables available from NI.

CMOS Reset Button

The NI-9154 has a CMOS reset button that you can use to reset the CMOS and the BIOS.

LEDs

The NI-9154 provides the following LEDs.


1378

POWER LED The POWER LED is lit while the NI-9154 is powered on. This LED is a bi-color LED. When the chassis is powered from V1, the POWER LED is lit green. When the chassis is powered from V2, the POWER LED is lit yellow.
USER FPGA LEDs You can use the bi-color, yellow and green USER FPGA LEDs to help debug your application or easily retrieve application status. Use the LabVIEW FPGA Module and NI-RIO software to define the USER FPGA LEDs to meet the needs of your application. Refer to LabVIEW Fundamentals for information about programming these LEDs.
