+Do this if the USRP becomes unresponsive to normal commands and cannot be found with uhd_find_devices.
+1. Load baseline_uhd.ndz onto a node with the extra ethernet card
+2. Boot up the node
+3. Download the latest firmware/UHD images to the node:
+{{{
+uhd_images_downloader
+}}}
+4. Configure eth2 to be able to talk to the USRP
+{{{
+ifconfig eth2 192.168.10.1 netmask 255.255.255.0
+}}}
+5. Remove lid of USRP
+6. Connect the USRP's ethernet to the node
+7. Put USRP in safe-mode:
+  a. Hold down the S2 button in the middle of the USRP's motherboard while power-cycling the USRP
+  b. Keep holding until the D & F status LED lights are stable and the left LED on the ethernet jack is green
+8. Check if the node can see the USRP:
+{{{
+uhd_find_devices --args="addr=192.168.10.2"
+}}}
+  If not, retry step 7
+9. Burn new firmware and FPGA images directly to the USRP:
+{{{
+usrp_n2xx_simple_net_burner --addr="192.168.10.2" --fw="/usr/share/uhd/images/usrp_n210_fw.bin" --fpga="/usr/share/uhd/images/usrp_n210_r4_fpga.bin" --dont-check-rev
+}}}
+10. Most likely the automatic reboot will fail so you will have to boot the USRP into safe-mode manually again
+11. Write new default ip into EEPROM:
+{{{
+/usr/lib/uhd/utils/usrp_burn_mb_eeprom --values="ip-addr=192.168.10.2"
+}}}
+12. Manually reboot the USRP into regular mode by just power-cycling it (do not hold down the S2 button)
+13. Check if the node can see the USRP:
+{{{
+uhd_find_devices --args="addr=192.168.10.2"
+}}}
+14. Test image loading:
+{{{
+uhd_image_loader --args="type=usrp2,addr=192.168.10.2"
+}}}
+15. Check if everything shows up correctly (versions, daughter-boards, etc):
+{{{
+uhd_usrp_probe
+}}}
