Compile *.beam locally, then send it to your server and reload it as mentioned in man pages:

http://erlang.org/documentation/doc-1/reference_manual/code_loading.html#id86381

-module(m).
-export([loop/0]).

loop() ->
    receive
        code_switch ->
            m:loop();
        Msg ->
            ...
            loop()
    end.
