7.Be sure a video expansion board, such as a RILOE 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 type 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. Refer to 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. Refer to the server documentation.

10.Be sure the server and the OS support the video expansion board.

Monitor does not function properly with energy saver features

Action: Be sure the monitor supports energy saver features, and if it does not, disable the features.

Video colors are wrong

Action:

•Be sure the 15-pin VGA cable is securely connected to the correct VGA port on the server and to the monitor.

•Be sure the monitor and any KVM switch are compatible with the VGA output of the server.

Slow-moving horizontal lines are displayed

Action: Be sure magnetic field interference is not occurring. Move the monitor away from other monitors or power transformers.

Mouse and keyboard problems

Action:

1.Be sure no loose connections (on page 15) exist. If a KVM switching device is in use, be sure the server is properly connected to the switch.

•For rack-mounted servers, check the cables to the switch box and be sure the switch is correctly set for the server.

•For tower model servers, check the cable connection from the input device to the server.

2.If a KVM switching device is in use, be sure all cables and connectors are the proper length and are supported by the switch. Refer to the switch documentation.

3.Be sure the current drivers for the operating system are installed.

4.Be sure the device driver is not corrupted by replacing the driver.

5.Restart the system and check whether the input device functions correctly after the server restarts.

6.Replace the device with a known working equivalent device (another similar mouse or keyboard).

•If the problem still occurs with the new mouse or keyboard, the connector port on the system I/O board is defective. Replace the board.

•If the problem no longer occurs, the original input device is defective. Replace the device.

7.Be sure the keyboard or mouse is connected to the correct port. Determine whether the keyboard lights flash at POST or the NumLock LED illuminates. If not, change port connections.

8.Be sure the keyboard or mouse is clean.
