2.3 Connecting External Devices to the Workstation

FIGURE 2-2 illustrates the external device cable connections to the workstation.

FIGURE 2-2 External Cable Connections

To connect external devices to the workstation:

1. Connect the workstation power cord to a grounded electrical outlet.

2. Connect the keyboard to a USB connector on the back or front panel.

3. Connect the mouse to the USB connector on the underside of the keyboard or

to a USB connector on the front or back panel.

4. Connect the Ethernet cable to the Ethernet connector on the Sun Ultra 24

Workstation, and connect the other end of the cable to an Ethernet RJ-45 jack.

Chapter 2 Unpacking, Cabling, and Powering the Sun Ultra 24 Workstation 2-5

5. Connect the monitor cable to the external port of the PCIe graphics card that is installed in the PCIe-2 slot (fourth slot from the bottom); see

FIGURE 2-3.

Your graphics card might require a DVI cable to connect to your monitor.

FIGURE 2-3 Connecting the Monitor to the System Image

6. Connect any additional external devices to the workstation’s other connectors.

2.4 Powering On the Workstation

To power on the workstation:

1. Turn on the power to the monitor and to all external devices.

2. Turn the power switch on the rear of the workstation to the On ( | ) position.

3. Press and release the power switch on the front panel.

2-6 Sun Ultra 24 Workstation Service Manual • November 2007

4. After several seconds, verify that the Platform Power LED next to the power switch is lit.

The Platform Power LED lights after the workstation begins the internal booting process.

5. If you need to change the system parameters in the BIOS, press the F2 key during the POST process to access the BIOS Setup Utility.

Caution – Be careful when making changes to the system BIOS, as some changes

can cause your system to malfunction.

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.

CHAPTER

Troubleshooting

This chapter describes visual inspection and troubleshooting procedures, and provides contact information if you require technical assistance. The following sections are included in this chapter:

■ Troubleshooting Overview

■ Section 3.2, “Visual Inspection” on page 3-2

■ Section 3.3, “Troubleshooting Procedures” on page 3-3

■ Section 3.4, “Obtaining Technical Assistance” on page 3-7

3.1 Troubleshooting Overview

Before troubleshooting your specific workstation problem, collect the following information:

■ What events occurred prior to the failure?

■ Was any hardware or software modified or installed?

■ Was the workstation recently installed or moved?

■ How long has the workstation exhibited symptoms?

■ What is the duration or frequency of the problem?

After you assess the problem and note your current configuration and environment, you can choose from several ways to troubleshoot your workstation.

■ Visually inspect your system as described in Section 3.2, “Visual Inspection” on

page 3-2.

■ See the troubleshooting procedures described in Section 3.3, “Troubleshooting

Procedures” on page 3-3.

■ Execute diagnostics tests as described in Chapter 4.

3-2 Sun Ultra 24 Workstation Service Manual • November 2007

If you are not able to resolve the problem, contact Sun technical support. Support numbers and web sites are listed in Section 3.4, “Obtaining Technical Assistance” on

page 3-7.

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.
