Appendix B: Troubleshooting
Device Front Panel ACCESS LED on PXI Module is Off
When PXI Chassis is On
If the ACCESS LED is not lit after you power on the PXI chassis, a problem may exist with the
PXI power rails, a hardware device, or the LED.
Note The LEDs may not light until the device has been configured in MAX. Before
troubleshooting this issue, verify that the device appears in MAX.
Troubleshoot this issue by completing the following steps:
1. Power off your PXI chassis.
2. Disconnect any signals from the PXI module front panel.
3. Remove the PXI module and inspect for signs of damage. Do not reinstall a damaged
device.
4. Reinstall the PXI module using the procedure described in step 5. Installing the Hardware.
5. Power on your PXI chassis.
6. Verify the device appears in MAX.
7. Reset the device in MAX and perform a self-test. Refer to step 6. Configuring and Testing
in MAX for information about performing device resets and self-tests in MAX.
8. If the ACCESS LED still fails to light, contact NI support at
ni.com/support.

1. In the MAX Configuration pane, click Devices and Interfaces to expand the category.
2. Click the appropriate Chassis and press <F5> to refresh the list of installed devices.

and restart.

to step 3.
