Troubleshooting |
This chapter contains information on troubleshooting procedures, power-on self-test (POST) codes and technical support contacts.
The following sections are included in this chapter:
Before troubleshooting your specific workstation problem, collect the following information:
After you assess the problem and note your current configuration and environment, you can choose from several ways to troubleshoot your workstation.
If you are not able to resolve the problem, contact Sun technical support. Support numbers and web sites are listed in Section 2.4, Technical Assistance.
Improperly set controls and loose or improperly connected cables are common causes of problems with hardware components. When investigating a system problem, first check all the external switches, controls, and cable connections. See Section 2.2.1, Performing an External Visual Inspection.
If this does not resolve your problem, then visually inspect the system's interior hardware for problems such as a loose card, cable connector, or mounting screw. See Section 2.2.2, Performing an Internal Visual Inspection.
1. Turn off the system and any attached peripherals (if applicable).
2. Verify that all power cables are properly connected to the system, the monitor, and peripherals, and check their power sources.
3. Inspect connections to any attached devices, including network cables, keyboard, monitor, and mouse, as well as any devices attached to the serial port.
1. Shut down the operating system, if necessary, and turn off the platform power on the front of the workstation.
2. Turn off the AC power on the back of the workstation.
3. Turn off any attached peripherals, but do not disconnect the power cables.
4. Remove the left-side panel, following the procedures in Section 4.2, Installation Precautions.
Caution - Some components, such as the heatsink, can become extremely hot during system operations. Allow these components to cool before handling them. |
5. Verify that the components are fully seated in their sockets or connectors and that the sockets are clean.
6. Verify that all cables inside the system are firmly attached to their appropriate connectors.
7. Replace the left-side panel.
8. Reconnect the system and any attached peripherals to their power sources, and then power them on.
TABLE 2-1 contains possible problems that might arise during the use of your workstation. Possible solutions are listed for each problem. If the solutions listed here do not fix the problem, run the appropriate diagnostic test (see Chapter 3).
Workstation does not power on when the front-panel Power button is pressed. |
Keep notes on the following situations in case you need to call Sun technical support:
|
Workstation halts during POST without displaying error messages. |
Check the BIOS POST LED display on the motherboard. See Appendix C for detailed information on the POST codes. |
CD or DVD does not eject from the media tray when you press the Eject button. |
|
Workstation does not power off when the front-panel Power button is pressed. |
|
An external device connected to a USB connector does not work. |
|
1. Turn off the workstation by pressing the Power button. 2. Remove the left-side panel. 3. Check to make sure that the power and data cables are connected to the disk drive and that the pins in the cable and connector are not bent. |
|
Workstation appears to be in low-power mode, but the Power button LED does not blink. |
The power-indicator LED blinks only when all workstation components are in low-power mode. A tape drive might be connected to your workstation. Because tape drives do not enter low-power mode, the power-indicator LED does not blink. |
Hung or frozen workstation: No response from mouse or keyboard or any application. |
Try to access your system from a different workstation on the network.
If the above procedures do not work: See Section 1.4.2, Powering Off the Workstation for more detailed information. |
