Testing the C2T chain
If the monitor, keyboard and mouse are known to be good, the only verification needed to be performed after connecting the C2T chain is the verification of the connections of the servers in the chain.
Follow these steps to test the C2T cabling:
1.Turn on all the servers and the monitor, verify that the light in the select button on server 1 in the C2T chain is lighted indicating it is selected. If it is not, press the select button.
2.Verify that the monitor is working.
3.Boot an operating system that has a mouse or pointing device driver. Verify the functionality of the mouse or pointing device.
4.Test your keyboard by typing a few words within an application.
5.Use your keyboard to switch to the last server in the chain. For example, if there are 42 servers in the chain: Press NumLock twice, press 4, press 2, press Enter. The monitor screen should go blank after the second NumLock, then become active again after the Enter is pressed showing the screen output of the selected server. Verify the keyboard and mouse functionality. If successful, the C2T chain is tested.
Note: If you were unable to perform steps 2 through 4, verify that the C2T breakout cable is properly connected to the C2T OUT port of server 1. Retry the test steps 2 through 4. If the problem persists, disconnect the C2T chaining cable from the C2T IN port of server 1. Retry the test. If the problem persists, the problem is due to either a faulty breakout cable or a faulty server. If the problem ceased to exist after the chaining cable was disconnected, the problem is probably caused by an anomaly in the chain. A procedure that could be
