    24 In order to access sb2, create a reservation in sb2 and have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on the COSMOS getting [https://wiki.cosmos-lab.org/wiki/GettingStarted started page] to get started.

    41 Follow the steps below to gain access to the sb2 console and set up nodes with appropriate images.
     45Follow the steps below to gain access to the sandbox console and set up nodes with appropriate images.
    4246 1. If you don't have one already, sign up for a [https://www.cosmos-lab.org/portal-2/ COSMOS account]
    43  1. [wiki:/GettingStarted#MakeaReservation Create a resource reservation] on COSMOS sb2
    44  1. [Documentation/Short/Login Login] into sb2 console ({{{console.sb2.cosmos-lab.org}}}) with two SSH sessions.
     47 1. [wiki:/GettingStarted#MakeaReservation Create a resource reservation] on COSMOS SB1 or SB2
     48 1. [Documentation/Short/Login Login] into sandbox console ({{{console.sb1.cosmos-lab.org}}} or {{{console.sb2.cosmos-lab.org}}}) with two SSH sessions.
    4549 1. Make sure all the nodes and devices used in the experiment are turned off:

    49  1. Use the {{{baseline-28ghz-paam.ndz}}} node image with Ubuntu 18.04, UHD 3.15, gnuradio 3.8, and the IBM 28GHz PAAM API. Load {{{baseline-28ghz-paam.ndz}}} on the server. 
    50 {{{#!shell
    51 omf load -i baseline-28ghz-paam.ndz -t srv1-lg1

     81* Upon logging into the server, run eth_config.sh script. This sets up the 10G data interfaces DATA1, DATA2. After running the script, you should see that the data interfaces have the appropriate IP addresses assigned, as per the tables for [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1#IPAddressAssignment SB1] and [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb2#IPAddressAssignment SB2].
