Mouse and keyboard issues
The mouse and/or keyboard are not operating normally.
-
Verify that all cables and cords are securely and properly connected. Check the following:
If you are using a KVM switching device, verify that the server is properly connected to the switch.
If you have rack-mounted servers, check the cables to the switch box to verify that the switch is correctly set for the server.
If you have tower model servers, check the cable connection from the input device to the server.
-
If you are using a KVM switching device, verify that all cables and connectors are the proper length and are supported by the switch.
For more information, see the switch documentation.
- Be sure the current drivers for the operating system are installed.
- Replace the driver with a known functioning driver to verify that the device driver is not corrupted.
- Restart the system. Check whether the input device functions correctly after the server restarts.
-
Replace the device with a known working equivalent device (a similar mouse or keyboard):
If the issue still occurs with the new mouse or keyboard, the connector port on the system I/O board is defective. Replace the board.
If the issue no longer occurs, the original input device is defective. Replace the device.
- 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.
- Clean the keyboard or mouse.
