OBI100 phone LED Off - Help?

Anyone can help? I switched to Verizon FiOS from Time Warner Cable. Then OBI100 phone LED being off. So OBI100 won't work?

Connections working fine before switching:

Cable modem To Linksys Router, then OBI100 to the router and the phone line.

Now the Connection are:

OBI100 to Verizon FiOS router and OBI100 to the phone line.

What went wrong? How can I make OBI phone LED solid again?

Thanks in advance.
