The Arduino board communicates with the shield using the SPI bus. This is on digital pins 11, 12, and 13 on the Uno
and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used as SS. On the Mega, the hardware SS pin, 53,
is not used to select the Ethernet controller chip, but it must be kept as an output or the SPI interface won't work.
