Issue Details

My PXI/PCI 85xx is not working. I am seeing red lights during operation. I was looking for a manual that describes when and what these lights mean to use in troubleshooting.

Solution

You can find information about the LED lights and other information about your device in the NI-XNET Hardware and Software Manual 

NI-XNET one and two-port boards include two LEDs per port to help you monitor hardware and bus status. LED 1 primarily indicates whether the hardware is currently in use. LED 2 primarily indicates the activity information of the connected bus. Each LED can display two colors (red or green), which display in the following four patterns:
 
PatternMeaning
OffNo LED illumination
SolidLED fully illuminated
BlinkBlinks at a constant rate of
several times per second
ActivityBlinks in a pseudo-random pattern
 
The following LED indications are protocol independent:
Condition/StateLED 1LED 2
Port IdentificationBlinks greenBlinks green
NI-XNET catastrophic errorBlinks redBlinks red
Open Session on hardware, port is properly powered,
and hardware is not communicating
Solid GreenOff
Open session on hardware, port is missing powerSolid RedOff

The following LED conditions are specific to CAN:
Condition/StateLED 1LED 2
Hardware is communicating, and controller is in Error Active stateSolid GreenActivity green (returns to idle/off
one second after last TX or RX)
Hardware is communicating, and controller is in Error Passive stateSolid greenActivity red (returns to idle/off one second after last TX or RX)
Hardware is running, and controller transitioned to bus offSolid greenSolid red

The following LED conditions are specific to FlexRay:
Condition/StateLED 1LED 2
Hardware is integrated with a FlexRay cluster,
and controller is in Normal Active state
Solid GreenActivity green (continues while integrated)
Hardware is integrated with a FlexRay cluster,
and controller is in Normal Passive state
Solid greenActivity red (continues while integrated)
Hardware was integrated with a FlexRay cluster and transitioned to Halt stateSolid greenSolid red

The following LED conditions are specific to LIN:
Condition/StateLED 1LED 2
Hardware is communicatingSolid greenActivity green (returns to idle/off one
second after last TX or RX)
