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

The LEDs may not light until the device has been configured in MAX. Before proceeding, verify that the PXI-5152 appears in 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.
Note Apply external signals only while the PXI-5152 is powered on. Applying external signals while the device is powered off may cause damage.
  1. Disconnect any signals from the module front panels.
  2. Power off the chassis.
  3. Remove the module from the chassis and inspect it for damage. Do not reinstall a damaged module.
  4. Install the module in a different chassis slot from which you removed it.
  5. Power on the chassis.
    Note If you are using a MXI controller, power on the chassis before powering on the computer.
  6. Verify that the module appears in MAX.
  7. Reset the module in MAX and perform a self-test.
If the ACCESS LED still fails to light and failures continue, contact NI technical support or visit ni.com/support.
