Optionally, you can connect the positive lead of another power supply to the other V terminal and the negative lead to one of the C terminals. Install the COMBICON connector on the front panel of the NI 9155. Caution To ensure the specified EMC performance, do not connect the power input to a DC mains supply or to any supply requiring a connecting cable longer than 3 m (10 ft).

Loads the FPGA bit stream from flash memory to the FPGA when the chassis powers on. If you want the NI 9155 to autoload and run a VI at powerup, you must also configure the VI to autoload before you compile it. For more information about autoloading VIs, refer to LabVIEW FPGA Module Help.
Link is established. Blinking yellow PCI Express clock is incompatible with NI 9155. Note For information about PCI Express clock compatibility with the NI 9155, go to and enter the Info Code ni.com/info 915xclock Powering Down the MXI-Express System Always power down the host system before powering down any connected NI 9155 chassis.
Figure 12. NI 9155 LEDs POWER LED The POWER LED is lit while the NI 9155 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.
NI 9155 may require less power in your application. For more information about the I/O module power requirements, refer to the module operating instructions. Physical Characteristics If you need to clean the chassis, wipe it with a dry towel.
