If the NI USRP-292x device cannot be found in the NI-USRP Configuration Utility or the IP address cannot be set, you must reconnect power to the device to enter the safe (read-only) image. Doing this will reset the device's IP to the default value of 192.168.10.2. For a step-by-step guide, see
Why Doesn't the Device IP Address Reset to the Default? in the getting started guide.
Above steps is not applicable to USRP-294X device.
