Start a Bourne shell (sh, bash, zsh) and use the for loop:

# for server in $( cat /path/to/serverlist ); do
scp /path/to/load_checker.sh user@${server}:/some/directory/
done

The $( ) construct tells the shell to run the command(s) between the $( ) and to substitute the values in place of the $( ).

The for loop will replace ${I} with each value returned by $( ).
