Cable Chaining Technology (C2T) ports

There are two C2T ports on the rear of the server. (They are labeled IN and OUT.) These ports, in conjunction with the C2T Chaining and the C2T breakout cables, are used to connect in a chain a maximum of 42 servers, allowing them to share a single video monitor, mouse, and keyboard.

Note: For best results, the highest video resolution that should be used with the C2T chain is 1024 x 768.

Connect the C2T breakout cable to the C2T OUT port of server 1. Server 1 is usually the server at the bottom of the rack. Connect the white connector of a C2T chaining cable to the C2T IN port of server 1. Connect the black connector of the C2T chaining cable to the C2T OUT port of the server above it. Refer to the following illustration for additional information. Repeat steps B and C for the other servers until all are connected together.

Note: The C2T breakout cables are available in the C2T cable option kit.
