Troubleshooting Microprocessor Problems The server emits a continuous tone during POST. Action A microprocessor is not working properly. 1. Verify that the secondary microprocessor is seated properly. 2. If your server contains two microprocessors, remove the secondary microprocessor and restart the server. If the server starts properly, replace the old secondary microprocessor. 3. If you have only one microprocessor, replace it. Restart the server. If the problem still exists, have the system serviced. Keyboard, Mouse, or PointingDevice Problems All or some keys on the keyboard do not work. The mouse or pointing device does not work. Action Verify that: 1. The server and the monitor are turned on. 2. The keyboard cable is securely connected to the keyboard connector on the server. For the location of the keyboard connector, see "Input/Output Connectors" on page 10. If the problem cannot be isolated and corrected, have the keyboard and system serviced. Verify that: 1. The mouse or pointing-device cable is securely attached to the proper connector on the server. Depending on the type of mouse that you have, the mouse cable will connect to either the mouse connector or the serial connector. To find the mouse and serial connectors, see "Input/Output Connectors" on page 10. 2. The device drivers for the mouse are installed correctly. If the problem cannot be isolated and corrected, have the server and the device serviced. Chapter 5. Solving Problems 165
