Why Is the ACCESS LED Off When the Chassis Is On?
The LEDs may not light until the module has been configured in MAX. Before proceeding, verify that the PXIe-4190 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.
Notice Apply external signals only while the PXIe-4190 is powered on. Applying external signals while the
module is powered off may cause damage.
- Disconnect any signals from the module front panels.
- Power off the chassis.
- Remove the module from the chassis and inspect it for damage. Do not reinstall a damaged module.
- Install the module in a different chassis slot from which you removed it.
- 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.
- Verify that the module appears in MAX.
- Reset the module in MAX and perform a self-test.
