4. Connect a C2T breakout cable to the C2T (OUT) connector on the first server in
the chain (server 1 in the illustration).
5. Connect the monitor, keyboard, and pointing device to the connectors on the
C2T breakout cable. The keyboard and pointing-device connectors on the cable
have icons to help you identify them.
6. Turn on the servers and test the chain, using the procedure in the following
section.
When you add, remove, or replace servers or change cables in the chain, it is
possible for the select LED on more than one server to be lit. Press the select
button on any server in the chain to turn off the select LEDs on all but the selected
server.
If you are using a flat-panel monitor, you might need to adjust the image lock on the
monitor. Press the select button on one of the middle servers in the chain; then,
adjust the image lock on the monitor. For more information about adjusting the
image lock, see the documentation that comes with your monitor.
Testing the C2T chain
After cabling the C2T chain, test the monitor, keyboard, and pointing device to
ensure that they work with each server in the chain. Complete the following steps to
test the chain:
1. With the servers and the monitor turned on, press the select button on server 1
in the chain.
2. Verify that the monitor is working properly.
3. Use the pointing device (mouse) to start an application.
4. Test the keyboard by typing a few words within an application.
5. Repeat steps 1 through 4 for each server in the chain.
If any of the devices do not work with any of the servers, verify that all the cables
are correctly and fully connected; then, test the chain again. If the problem remains,
turn off all the servers and disconnect all the C2T interconnect cables; leave the
C2T breakout cable connected. Turn on server 1 and retry the devices. If the
devices work, one of the C2T interconnect cables is probably defective. Connect
server 2 to the chain and test the devices again. Continue adding servers to the
chain and testing them, one at a time, until you identify the defective cable.
Using the C2T chain
To select the server for which you want the monitor, keyboard, and pointing device
to work, press the select button on the server, or you can select the server by using
the keyboard:
1. Press Num Lock on the keyboard twice. The monitor screen goes blank.
2. Type the number of the server in the chain and press Enter. The monitor now
displays the image for the selected server, and the select LED on the selected
server is lit.
After you have used the keyboard to specify a server number, you can use the
same method (pressing Num Lock twice, then pr or -) to select other
servers in sequence.
Note: You cannot use the + and - keys to select a server if you made the previous
selection by pressing the select button on the selected server; you must
have made the previous selection through the keyboard.
