    25  As shown in the figure above, Sivers control software runs on srv3,srv4, whereas the UHD/gnuradio application to generate/process data samples runs on srv1,srv2. So, appropriate images have to loaded on these servers.

    2626 The image sivers_sb1_cosmos.ndz, has UHD and Sivers control software installed.
    2727* Load sivers_sb1_cosmos.ndz on srv3,srv4

    66 * Configure 10G data interface 
     66* The IP addresses for Ethernet Port 1(10G) on the X310s sdr2-md2 and sdr2-md3 were hard-coded to 10.115.2.2 and 10.115.2.3 respectively. To access them from srv1-lg1 or srv2-lg2, configure the network interface eno2 as follows
