Do you have display on screen? If yes, check http://www.intel.com/support/motherboards/server/sb/CS-031644.htm
Yes, I have. there are two informations:
PXE-E61 media test failure, check cable
PXE-MOF: exiting intel Boot Agent
So the beeps don't indiate errors. The messages are showing because the server is trying to boot from network. If you set proper boot order in BIOS those messages should be gone.
