Have you tried a different cable? I've seen computers not get DHCP because one of the 8 wires in the ethernet cable is damaged. Also look at the pins inside the X360 NIC to see if any of them are bent or damaged, do the same on your switch or router also. You may also try a different port on the router.
If this doesn't work, you may have an issue with the X360's NIC.
