     1== N310 configuration and access ==
     2
     3=== Description ===
     4
     5This tutorial shows how to configure and access the N310 SDR from an experiment server. The N310 is used as a network based USRP which has a 1Gb control interface and a 10Gb data interface. Both interfaces need to be configure properly for control and data streaming. Product information for the N310 is [https://www.ettus.com/all-products/usrp-n310/ here].
     6
     7=== Network configuration ===
     8From a COSMOS console, load a baseline sdr image onto an experiment server - for this example ''srv1-lg1.sb1.cosmos-lab.org'' is used.
     9{{{
     10console> omf load -i baseline-uhd-1804.ndz  -t srv1-lg1.sb1.cosmos-lab.org
     11console> omf tell -a on -t srv1-lg1.sb1.cosmos-lab.org
     12}}}
     13
     14After the experiment server is up, ssh into it and list the all interfaces.

     287The FPGA bit file will need to be updated if FPGA version mismatch is generated in the output text of the uhd command above. Follow the steps below to update the FPGA image - this will download and install the FPGA image that is matched with the UHD version being used. Complete details on updating the FPGA  is found [https://kb.ettus.com/USRP_N300/N310/N320/N321_Getting_Started_Guide#Updating_the_FPGA_Image here].
