Why Is the Access LED Off When the Chassis Is On?

The LEDs may not light until the module has been configured in Hardware Configuration Utility or MAX. Before proceeding, verify that the PXIe-4190 appears in Hardware Configuration Utility or MAX.

If the Access LED fails to light after you power on the chassis, a problem may exist with the chassis power rails, a hardware module, or the LED.

Notice Apply external signals only while the PXIe-4190 is powered on. Applying external signals while the module is powered off may cause damage.
  1. Disconnect any signals from the module front panel.
  2. Power off the chassis.
  3. Remove the module from the chassis and inspect it for damage.
    Notice Do not reinstall a damaged module.
  4. Install the module in a different, supported slot within the same PXI chassis.
  5. Power on the chassis.
    Note If you are using a PC with a device for PXI remote control system, power on the chassis before powering on the computer.
  6. Verify that the module appears in Hardware Configuration Utility or MAX.
  7. Reset the module in Hardware Configuration Utility or MAX and perform a self-test.
