Antminer S2 boots just fine but does not communicate. No Hashing

[ljfinkey]

Hi, My mining shelf got bumped today and 1 of my Antminer S2 units powered off.  When I powered it back on, it went through the startup just fine up to the IP address screen but will not communicate.  I checked the inner and exterior network cable connection.  I reseated the boards and flashed a new SD card but the same result.  I tried connecting directly from my laptop to the Antminer, bypassing my router but still no communication.  The unit is about 2 weeks old.  Any advice I could get would be greatly appreciated.  Thank You!
