Hi lvrmo,

 

If only the F LED is powered on and you cannot see the device in the Configuration Utility, it may be that the you are having trouble locating the device over the network or the USRP firmware became corrupted. Please try the following sections of the NI USRP Getting Started Guide:

 

- Why Doesn't the USRP Device Appear in the NI-USRP Configuration Utility?

- Why Doesn't the Device Respond to a Ping (ICMP Echo Request)?

- Why Doesn't the NI-USRP Configuration Utility Return a Listing for My Device?

- Why Doesn't the Device IP Address Reset to the Default?

As a last resort you can also boot into safe mode.  

 

Its possible to put the device into an unusable state by loading bad images. Fortunately, the 292x and 293x  devices can be booted into a safe (read-only) image. Once booted into the safe image, the user can once again load images onto the device.

The safe-mode button is a pushbutton switch (S2) located inside the enclosure. To boot into the safe image, hold-down the safe-mode button while power-cycling the device (plugging in the power connector on the front panel). Continue to hold-down the button until the front-panel LEDs blink and remain solid.

 

When in safe-mode, the 292x or 293x device will always have the IP address 192.168.10.2.
