Having trouble in runnning the LwIP Ethernet test with my zc706

hello, i was trying to connect my zc706 to my pc using TES. But I couldn't connect. So I tried to  follow the guide in the xtp242-zc706-bist (from Xilinx)to run the Lwip design from the SDK. I skip to do the lwip test and I make sure all the switches are put in right states and all of the jumpers are on default states.I set my computer to the ip address  following the guide in page 43 and 44.Then I run the lwip_echo_server however it doesn't respond.  I try to ping 192.168.1.10,but the connection is timed out. Is there any test that I can run to check my ethernet port is still working? Or do i miss some steps to run the LWIP design?
