using sd card with arduino ethernet board

Hello !
how I sould do ??
My problem how the arduino ethernet board can be powered ?
(the arduino has a microSD card reader, and ethernet module and we don't need an ethernet shield )

Please re-phrase your question.
I don’t understand what you are asking.

I have arduino ethernet board (not arduino + ethernet shield).
I would like to upload sketches in arduino using foca (usb to serial converter) but it does not work for me.
So I would ask if it is possible to upload sketches by using microsd card ?
Thanks !
