Refer to Table 3 for USB device port pin locations and signal descriptions.

Caution Do not hot-swap USB devices while the cRIO controller is in a hazardous

location or connected to high voltages. If the cRIO controller is not in a hazardous

location, you can connect and disconnect USB devices without affecting operation.

RESET Button

Pressing the RESET button resets the processor in the same manner as cycling power.

You can also use the RESET button to troubleshoot network connectivity:

1. Hold the RESET button for 5 seconds, and then release it to boot the controller in safe mode

and enable Console Out.

2. After booting the controller into safe mode, hold the RESET button again for 5 seconds to

boot the controller into safe mode, enable Console Out, and reset network adapters to

default settings.

For more information about using the RESET button to put the controller into safe mode and

troubleshoot network issues, refer to the Troubleshooting Network Communication section.

Power Button

The default behavior for the cRIO controller is to power on when you apply power to the

controller and power off when you press and release the power button, shown in Figure 1. The

behavior of the power button can be configured in the BIOS. If the cRIO controller becomes

unresponsive, you can power it off by holding the power button for 4 seconds.

LEDs

The cRIO controller features four LEDs—POWER, STATUS, USER1, and USER FPGA1—on

its front panel as shown in Figure 1. Table 4 lists the LEDs and status indications.
