connectivity

I am a novice cisco user and I am trying to investigate as to why one of our connections went down.

We have a fiber network ring that is operating just fine. Connected to this ring via ethernet, is a lone 3560. This connection has worked flawlessly for the past year and a half. This morning, I noticed that I could not connect to that remote switch.

I checked the configurations on both switches, and nothing has changed (as I expected). In the field, the port lights were flashing, indicating that some sort of communication is occurring. There is only 1 ethernet cable that has been run between these two locations, so testing an alternate path is not possible.

What else can I do to fix this connection?
