Compatible boards ?? Arduino UNO R1 ( NO rev) with Ethernet Shield R3

The IOREF from the Ethernet Board touches the casing of one of the capacitor . Do I have to isolate that pin ????

Would not want to blow anything , I have not found the info in FAQ or other pages .

Thanks

It is never a good idea to have possible electrical connections where you don't want them. At a minimum place a piece of electrical tape on the IOREF pin, or try and bend the capacitor so it is out of the way.
