The device may be configured for DHCP but unable to get an IP
address because of a problem with the DHCP server. Check the
network connection and try again. If the problem persists, contact
National Instruments.
The cRIO-9081 indicates specific hardware error conditions by flashing the STATUS LED red
a certain number of times every few seconds, as shown in the following table.
Table 13.
STATUS LED Hardware Indicators
Pattern of Red
Flashes
Indication
Continuously Flashing An internal power supply has failed. Check front-panel I/O, CXM,
and C Series module connections for shorts. Remove any shorts and
power cycle the controller. If the problem persists, contact National
Instruments.
Solid
The cRIO-9081 internal temperature has exceeded a critical
threshold. Ensure that the ambient operating temperature does not
exceed the range specified in the
Environmental
section. If the
problem persists, contact National Instruments.
User LEDs
You can define the USER1 and USER FPGA1 LEDs to meet the needs of your application.
The following table lists the USER1 and USER FPGA1 LED indicators.
