yes.
i did all like in manual for netinstall in wiki.but no result

Try to use reset button on RB2011,
- power on the board;
- push reset button within 2 seconds after power is applied;
- hold reset button for ~15 seconds;
- release reset button.

Make sure Netinstall computer is connected to Ether1 port, and correct configuration is applied for it,
