- Check your Keyboard-Video-Mouse (KVM) switch. If the system is connected to a monitor, mouse, and keyboard through a Keyboard-Video-Mouse (KVM) switch, or console selector switch, then disconnect the switch and connect monitor, mouse, and keyboard directly to the system. If this solves the issue, please contact your switch manufacturer for support and compatibility on the switch. Some switches can have a firmware update applied to resolve common problems.
Note: BladeCenter Telco chassis - The KVM module contains keyboard port, mouse port, Power LED, Location LED, Critical Telco Alarm LED, Major Telco Alarm LED, Minor Telco Alarm LED and a video port. The PS2 keyboard and mouse connectors are standard 6-pin Mini Din. The Telco alarms mirror the Telco alarms located on the front panel of the media tray because they use the same signal lines. The KVM module allows the connection of a VGA monitor for system maintenance and control. The video connector is a standard 15-pin VGA. The KVM module is hot-swappable. It is docked into an edge card connector located on the backplane:
- If you have your system daisy chained for KVM capabilities using the C2T port (e.g. xSeries 330),
then you must flash the C2T firmware after flashing the system BIOS, in order for the mouse and keyboard to work. Otherwise, after a BIOS flash, you will lose keyboard/mouse capabilities unless you walk up to each machine and push the select button.
- If you are using NetBAY Advanced Connectivity Technology (ACT) CAT5 cabling in your rack server, instead of KVM cabling, click here for ACT information.
- Check for POST/startup errors. If you are getting a POST/startup error on the keyboard and/or mouse:
- Verify that all items are firmly connected to the correct ports, and that the cables are undamaged with no bent pins. The PS/2 style mouse and keyboard ports look identical, but are not interchangeable. The mouse and keyboard must be attached to the correct ports in order to be recognized by the system and to function correctly.
- Swap each item for known good units. If a new item works where the original did not, then the original component must be faulty.
- If the keyboard works during the POST/BIOS screens, but not in the operating system, check software logs for device driver errors. Contact your software vendor for more support in configuring the I/O devices.
- Check the F1 Setup error logs for system component failures or errors. These are found under Event/Error Logs. Troubleshoot suspect components further to determine if the hardware is faulty. If an IBM component is determined to be faulty, please contact your local IBM Support Center for warranty replacement of the part(s). Please have the Field Replacement Unit (FRU) / Customer Replacement Unit (CRU) part number and Machine Type, model and serial number ready.
- Run hardware diagnostics. Replace any parts found defective.

- If you can down the system, check the keyboard cable connector on the system unit for proper voltage.
- Power off the system.
- Disconect the keyboard cable form the system unit.
- Power on the system and check the keyboard cable connector on the system unit for the voltages shown:
- If the voltages are not correct, replace the system board. Otherwise, replace the keyboard.
- If these steps have not solved your problem:
