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 (FIGURE 1-1).

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 (FIGURE 1-1).

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.

Caution - Be careful when making changes to the system BIOS, as some changes can cause your system to malfunction.

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 FIGURE 1-2).

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 for more options.

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.
