FIGURE 1-5 External Cable Connections

Figure showing cable connections for the Sun Ultra 20 M2 Workstation

Perform this procedure 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 either Ethernet connector on the Sun Ultra 20 M2 Workstation, and connect the other end of the cable to an Ethernet RJ-45 jack.

5. Connect the monitor cable as follows:

If a PCI Express graphics card is not installed in the top PCI-E slot, connect the monitor to the onboard video connector. See the top of FIGURE 1-6.

If a PCI Express graphics card is installed in the top PCI-E slot, connect the monitor to the graphics card connector. See the bottom of FIGURE 1-6.

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

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

1.8 Powering On the Workstation

Perform this procedure 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.

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.

1.9 Powering 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.

1.10 Adding/Removing Devices To/From the Boot Menu

The boot menu lists the devices from which the system can boot. If you want to boot from a newly installed or attached device, you must add it to the boot menu.

To add or remove devices to/from the boot menu (accessed by pressing the F8 key during boot), perform the following steps:

1. Press the F2 key during system boot.

The BIOS Setup screen displays.

2. In the Boot Settings menu, add or remove the device from the boot device list.

3. Press the F10 key to save your settings and exit.
