    11 === Set up ===
    12 For this example we used the USRP 2974 SDR on [wiki:Architecture/Domains/cosmos_sb1 sandbox 1]. Follow the steps below to gain access to this console and set up your node with an appropriate image.
     11=== Resources required ===
     12For this example we used one USRP 2974 SDR on [wiki:Architecture/Domains/cosmos_sb1 sandbox 1].

     14=== Tutorial Setup ===
     15 Follow the steps below to gain access to this console and set up your node with an appropriate image.
    1316 1. Sign up for a [https://cosmos-lab.org/portal-2/ COSMOS account].
    1417 2. [GettingStarted#MakeaReservation Create a resource reservation] for sandbox 1.
    1518 3. Once reservation is approved, [wiki:GettingStarted#LogintoyourReservation login into the console].
    16  4. Use OMF commands to [GettingStarted#ControlResourceswithOMF load baseline_uhd.ndz image] on your resource.
    17 
    18 When opening a terminal into console.sb1.cosmos-lab.org [set up a tunnel] from localhost:5002 to sdr2-lg1.sb1.cosmos-lab.org:9002. This will be used by the web app to connect to a server running on the Krypton's host.
    19 
    20 === Configure and detect the radio ===
    21 * Once your node is ready and turned on, ssh into the Krypton's host
    22 {{{#!shell-session
    23 console:~$ ssh root@sdr2-lg1.sb1.cosmos-lab.org
    24 }}}
     19 4. Use OMF commands to [GettingStarted#ControlResourceswithOMF load baseline-uhd.ndz image] on your resource.
     20 {{{#!shell
     21 omf load -i baseline-uhd.ndz -t sdr2-s1-lg1
     22 }}}
     23 1. Once the node is successfully imaged, turn it on and check the status
     24 {{{#!shell
     25 omf tell -a on -t sdr2-s1-lg1
     26 }}}
     27 {{{#!shell
     28 omf stat -t sdr2-s1-lg1
     29 }}}
     30 1. After giving it some time to power up and boot, ssh to the node
     31 {{{#!shell
     32 ssh root@sdr2-s1-lg1
     33 }}}
     34 
     35
     36When opening a terminal into console.sb1.cosmos-lab.org [wiki:/UserGuide/RemoteAccess/SshTunnel set up a tunnel] from localhost:5002 to sdr2-s1-lg1.sb1.cosmos-lab.org:9002. This will be used by the web app to connect to a server running on the USRP 2974(Krypton)'s host.
