POWER LED
The POWERLED is lit while the NI 9148is powered on. This LED
indicates that the power supply connected to the chassisis adequate.
USER FPGA1 LED
You can use the USER FPGA LED to help debug your application or easily
retrieve application status. Use the LabVIEW FPGA Module and NI-RIO
software to define the USER FPGA1 LED to meet the needs of your
application. Refer to LabVIEW Help for information about programming
this LED.
STATUS LED
The STATUS LED is off during normal operation. The NI 9148indicates
specific error conditions by flashing the STATUS LED a certain number of
times every few seconds, as shown in Table 2.

Indication
1
The chassis is unconfigured. Use MAX to configure the chassis. Refer
to the Measurement & Automation Explorer Help for information about
configuring the chassis.
2
The chassishas detected an error in its software. This usually occurs
when an attempt to upgrade the software is interrupted. Reinstall
software on the chassis. Refer to the Measurement & Automation
Explorer Help for information about installing software on the chassis.
3
The chassis is in safe mode because the SAFE MODE DIP switch is in
the ON position. Refer to the
Configuring DIP Switches
section for
information about the SAFE MODE DIP switch.
