• The C2T numbering is independent of any other server reference. Changing the
servers position in the C2T chain will not effect their IP addresses.
Note:
Operational notes:
1. Server 1 (usually the server at the bottom of the rack) is the server to which you
connect the C2T device break out cable.
2. Server 1 must not be turned off (powered down) for the chain to work properly.
3. If server 1 is turned off (powered down) it must be removed from the chain and
replaced by the next server in the chain.
4. For the chain to operate properly no more than two adjacent servers can be
unplugged from the wall outlet at the same time.
5. If you are using a flat panel monitor, you might need to adjust the image lock on
your monitor when multiple servers are connected using C2T interconnect cables.
To adjust this image, select one of the middle servers in the chain by pressing the
select button on the front of the server; then, adjust the image lock accordingly.
For more information on how to adjust the image lock, refer to the documentation
that came with your flat panel monitor.
6. When removing or replacing servers, or changing cables in the chain, it is possible
for more than one select LED to be illuminated on the servers in the chain. To
clear all but the selected server LED, press the select button on any one of the
servers in the chain.
7. If you turn off a selected server you must select another server that is powered up.
For the location of the select button see “Server controls and indicators” on page
6.
8. For your C2T chain to work properly with your operating-system, enable or
disable the settings as shown in the following table.
Complete the following steps to connect the servers:
1. Gather several of the C2T cables.
Note: The server comes with a short C2T chaining cable that can span
approximately 3 Us if needed. A longer C2T cable is available in the C2T
cable option kit.
2. Connect the servers together:
a. Connect the C2T breakout cable to the C2T OUT port of server 1.
Note: Server 1 is usually the server at the bottom of the rack.
b. Connect the white connector of a C2T chaining cable to the C2T IN port of
server 1.
c. 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.
d. Repeat steps b. and c. for the other servers until all are connected together.
