2.5 Powering Off the Workstation

To power off the workstation:

1. Save your data, and close any open applications.

2. Read both of the following power-off options, and then follow one of the options to turn off the workstation.

■ Power off the workstation by using the operating system shutdown command

or menu option.

■ In most cases, this initiates an orderly shutdown of the operating system and

shuts off the workstation power.

Caution – To avoid data loss, use the first option whenever possible.

■ If the first option does not shut off the workstation power, press and hold the

power button for approximately four seconds.

This option shuts down the power to the workstation but does not initiate an orderly shutdown of the operating system. This option might result in data loss.

If the proceeding options do not power off the workstation, turn the power switch on the back panel to the off ( 0 ) position.

After powering off the workstation, wait at least four seconds before powering on the workstation again.

3.2 Visual Inspection

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 external switches, controls, and cable connections.

If an external visual inspection does not resolve your problem, visually inspect the system’s interior hardware for problems such as a loose card, cable connector, or mounting screw.

3.2.1 To Perform an External Visual Inspection

1. Shut down the operating system, if necessary, power off the platform power on the front of the workstation and power off 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.

3.2.2 To Perform an Internal Visual Inspection

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 access panel, following the procedures in Section 5.2,

“Opening the Workstation” on page 5-2.

Caution – Some components, such as the heatsink, can become extremely hot

during system operations. Allow these components to cool before handling them.

Chapter 3 Troubleshooting 3-3

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 access panel.

8. Reconnect the system and any attached peripherals to their power sources, and then power them on.

4.5 Immediate Burn In Testing

The Immediate Burn In Testing option enables you to run Burn In test scripts on your workstation. Three scripts were created for testing your system:

■ quick.tst – This script performs a non-detailed test of all hardware

components, including those components that require user input, as well as a more in-depth memory test. You must interact with the Pc-Check software to progress through these interactive tests. These interactive tests cannot be run unattended and do not contain any “timeout” facilities. The interactive tests will wait until you provide the correct input.

■ noinput.tst – This script is used as a triage of any hardware-related problems

or issues. The script performs a non-detailed test of most hardware components, excluding those components that require user input (keyboard, mouse, sound, video). This test does not require user input.

■ full.tst – This script performs the most detailed and comprehensive test on all

hardware components, including those components which require user input. This script contains a more in-depth memory test than quick.tst, as well as external port tests (which might require loopback connectors). You must interact with the test utility to progress through these interactive tests.

Tip – Each of these scripts tests the operating status of your entire system. If you

want to test only a certain percentage of your system’s hard drives, see Section 4.4.1,

“Hard Drive Testing” on page 4-6 for information about how to change the test

options.

When you select the Immediate Burn In Testing menu option, the Continuous Burn In Testing window appears. The window includes the list of options shown in
