1.4 Powering the Workstation On and Off

1.4.1 Powering On the Workstation

After making sure that you set up the system properly and connected all the
required cables explained in the Sun Ultra 20 Workstation Getting Started Guide,
819-2148, you can now power on your system.

Tip – If you are installing optional internal components such as additional memory

DIMMs, PCI cards, optical drives, or hard drives, install those components before
you power on the workstation. See Chapter 4 for remove and replace procedures. If
you are not installing optional components, you are ready to power on the
workstation.

Follow these steps 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 workstation Power button on the front panel (

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

The platform power LED lights after the workstation begins the internal booting
process (

5. After the system finishes booting, configure the preinstalled Solaris 10 Operating
System or install another supported operating system.

See the Sun Ultra 20 Workstation Getting Started Guide, 819-2148, for more information
on configuring the preinstalled operating system or installing an additional
operating system.

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.

FIGURE 1-1).

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

can cause your system to malfunction.

FIGURE 1-1).

1.4.2 Powering Off the Workstation

1. Save your data and close any open applications.

2. Read all of the following power-off options before powering off the workstation:

■ Power off the workstation by using the operating system shut down command or

menu option.
In most cases, this will power down the operating system, then turn off the power

to the workstation.

■ If the workstation power does not shut off through the operating system

command or this command is not available, press and release the Power button
(location shown in

This initiates an orderly shutdown of the operating system and powers off the
workstation.

Caution – To avoid data loss, use one of the first two options whenever possible.

■ If the workstation power is not shut off with one of the first two options, press

and hold the Power button for approximately four seconds.
This shuts down the power to the workstation but does not initiate an orderly

shutdown of the system. This method could result in data loss.

If the proceeding options fail to power off the workstation, see Chapter 2, Section ,

“Troubleshooting” on page 2-1 for more options.

FIGURE 1-2).

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

1.4.3 Power Interruptions

If the power to the system is interrupted for less than ten seconds, do the following
to ensure that the standby power is completely shut off:

1. Unplug the AC power cord from the workstation or turn off the power switch on
the back panel of the workstation.

2. Wait ten or more seconds.

3. Plug the power AC cord into the workstation.

4. Power on the workstation.

3.4 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. The user 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 the user provides the correct input.

■ noinput.tst – This script is used as a first 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 may require loopback connectors). The user must
interact with the test utility to progress through these interactive tests.

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

want to test only a certain percentage of your system’s hard drives, refer to

Section 3.3.1, “Hard Disk Testing” on page 3-6 to change the test options.

When you select the Immediate Burn-in Testing menu option, the Continuous Burn­in Testing window displays. The screen includes the list of options shown in

3.6 Create Diagnostic Partition

The diagnostic partition is preinstalled on the Sun Ultra 20 Workstation. You need to
reinstall the diagnostic partition only if you reformatted your hard drive. Using the
Erase Primary Boot Hard Disk utility on the Supplemental CD preserves the
diagnostic partition.

The Create Diagnostic Partition option installs a diagnostic partition on the first
bootable disk seen by the Sun Ultra 20 Workstation. The first bootable disk is on the
primary/master SATA device.

The following sections explain how to create and access the diagnostic partition on
the Sun Ultra 20 Workstation:
