Your phone is trying to connect to a TFTP server address to download a firmware and/or config file update. You need to figure out what IP address it is trying to connect to (You may have to use wireshark or another packet sniffer to determine this).
Once you know the IP it is trying to connect to, you'll need to set up a small network with a TFTP server running on that same address, and feed the phone a firmware update and/or config file. It will likely not fully boot unless it gets a firmware update.

If there are lines through your line appearances than your phone is likely not properly registered with your Callmanager or SIP registrar, you need to configure your phone properly so it registers and associates with an extension on your PBX or hosted service.
These phones can take their power from a Power over Ethernet switch, where all you need to do is plug the phone in to the switch and it gets its power from there.
You can also get power cubes for these phones, but they do not come with the phone as standard, as most people like the convenience of having the power coming from the switch, and not needing to use up a further power socket in the floor/wall.
Here's a great little document from Cisco directly, called "Converting a Cisco 7940/7960 CallManager Phone to a SIP Phone and the Reverse Process" Easy to do, just follow the step-by-step directions. http://www.cisco.com/en/US/products/hw/phones/ps379/products_tech_note09186a0080094584.shtml
You will need to modify the template assigned to that particular phone. Depending on the service you are using (CallManager onsite or hosted VoIP, or other options), you may or may not actually have access to make these changes.
