o For rack-mounted servers, check the cables to the KVM switch and be sure the switch is correctly set for the server. You may need to connect the monitor directly to the server to be sure the KVM switch has not failed. o For tower model servers, check the cable connection from the monitor to the server, and then from the server to the power outlet. 5. Press any key, or enter the password, and wait a few moments for the screen to activate to be sure the energy saver feature is not in effect. 6. Be sure the video driver is current. For driver requirements, see the third-party video adapter documentation. 7. Be sure a video expansion board has not been added to replace onboard video, making it seem like the video is not working. Disconnect the video cable from the onboard video, and then reconnect it to the video jack on the expansion board. NOTE: All servers automatically bypass onboard video when a video expansion board is present. 8. Press any key, or enter the password, and wait a few moments for the screen to activate to be sure the power-on password feature is not in effect. You can also tell if the power-on password is enabled if a key symbol is displayed on the screen when POST completes. If you do not have access to the password, you must disable the power-on password by using the Password Disable switch on the system board. See the server documentation. 9. If the video expansion board is installed in a PCI hot-plug slot, be sure the slot has power by checking the power LED on the slot, if applicable. See the server documentation. 10.
