If your computer is configured for the ResNet, just plug in and enjoy full access to all of the resources of the campus network.
Ethernet cables are available for checkout at the Reserves Desk.
CMC 2 ports are available in the CMC help desk lounge, next to the candy machine. Your computer must already be configured for the residential ethernet in order to use these ports. If you attempt to use them without a ResNet setup, you can trash the settings on your computer. If you have trouble using these ports, please verify that your computer works in your room, and try another port and another cable before reporting that a port is bad.
