Install the Graphics Tower Legs

To install the legs on the Graphics Tower, you need one of the following tools:

Remove the Graphics Tower legs and hardware from the shipping container and install the legs with the hardware supplied. See Figure 5-1 for reference.

    Figure 5-1 Install the Legs Onto the Graphics Tower

    1. Locate the four round plastic covers (two on each side) that are nearest the bottom of the Graphics tower.

    Push in on the small recessed dot on the round plastic cover to make the cover protrude. Remove the plastic covers to expose the screws that attach the legs to the tower. See Figure 5-2.

    Figure 5-2 Plastic Cover

    2. Using a 10mm nut driver or a flat-blade screwdriver, remove the two screws nearest the bottom of the tower.
    3. Align the two holes in the tower with the two holes in the legs.
    4. Insert the screws, tighten, and reinsert the plastic covers into the leg holes.
    5. Set the Graphics Tower on its other side with the attached leg protruding downward.
    6. Repeat the instructions in steps 1 through 4 for the remaining leg.
    7. Set the Graphics Tower upright and place it into the desired position.
    8. Insert the air filter into the slot at the base of the Graphics Tower between the two legs.

Connect the Cables

You will now connect the host adapter cable, the video cable, and the two ac power cables.

Connect the Host Adapter Cable

To install the host adapter cable:

    1. Locate the host adapter cable.

    The host adapter cable has gray metal connectors on both ends. See Figure 5-3.

    2. Connect one end of the host adapter cable to the connector marked HOST on the rear of the Graphics Tower.

    See Figure 5-3. Align the plug on the cable with the connector on the Graphics Tower, squeeze the two release levers on the plug, and push the plug into place.

    3. Connect the other end of the host adapter cable to the GT SBus Adapter Board connector on the rear of the system unit.

    See Figure 5-3.

    Figure 5-3 Connect the Host Adapter Cable

Connect the Video Cable

Note - The following information refers to connecting the Sun 21-inch color monitor supplied with the GT Graphics Subsystem. If you wish to install another type of monitor, refer to the connector descriptions in Appendix A.

Refer to Figure 5-4 to install the video cable. Install the video cable as follows:

    1. Locate the video cable.

    See Figure 5-4.

    2. Remove the plastic protectors from both ends of the cable.
    3. connect either end of the cable to the connector on the monitor back panel.

    Hand tighten the two screws on either side of the plug by turning the screws clockwise.

    4. Connect the other end of the cable to the MONITOR connector on the rear of the Graphics Tower.

    Hand tighten the two screws on either side of the plug by turning the screws clockwise.

Note - Video cables supplied by Sun are of sufficient length to meet the needs of most installations. If you have special cable length requirements, ask your Sun sales representative about the availability of alternate cables.

    Figure 5-4 Install the Video Cable

Connect the Power Cable

Caution -

Make certain that the ac power switches of the Graphics Tower, the system unit, and the color monitor are off.

The off position of the ac power switch on the system unit and the GT Graphics Tower is with the side marked "O" pushed in.

The off position of the ac power switch on the color monitor is with the switch in the out position.

Note - For operation on 230 volts, replace the fuse as described under "Voltage Selection" on page 4.

    1. Find the three ac power cables; one each for SPARCstation, GT Graphics Tower, and color monitor.

    The ac power cable has a three-slot female plug at one end and a three- pronged wall plug at the other.

    2. Plug the female end of one of the ac power cables into the power receptacle on the Graphics Tower.
    3. Plug the female end of one of the ac power cables into the power receptacle on the rear of the system unit.
    4. Plug the female end of one of the ac power cables into the power receptacle on the rear of the color monitor.
    5. Plug the male end of each of the three ac power cables into a power outlet.

Install the Cable Management Bracket

The cable management bracket protects and restrains the cables behind the Graphics Tower. After all the cables have been installed, install the cable management bracket as follows:

    1. Align and snap the cable management bracket onto the plastic rails at the rear of the tower.

    See Figure 5-5. A moderate push should be all that is necessary to properly seat the bracket snaps on the rails.

    Figure 5-5 Install the Cable Management Bracket

    2. Adjust the cable management bracket by sliding it along the rails.

    The bracket should be approximately in the vertical center of the rails.

    3. Snap the cables into the bracket if desired.

    See Figure 5-6.

    Figure 5-6 Snap the Cables to the Cable Management Bracket

Review the Installation

Before powering on the system, verify that everything is installed properly. Make certain that:

    1. The GT SBus Adapter Board is installed in the system unit and the system unit cover is on.
    2. The GT Graphics Tower is in the upright position on its supporting legs.
    3. The host adapter cable is properly connected.
    4. The video cable is properly connected.
    5. The ac power cables are properly connected.
    6. The system unit, color monitor, and Graphics Tower have the correct ac power source (as listed on the back of each unit).

After you have verified that everything is properly installed, power on the system as described on the next page.

Power on the System

Power-on the system in the following order:

Note - It is important that you power on the monitor and the Graphics Tower before you power on the system unit. This is necessary to allow the system unit to initialize the drivers it uses to communicate with the GT Graphics Subsystem .

    1. Turn on the color monitor.

    The ac power switch is "ON" when the switch is pushed in.

    2. Turn on the Graphics Tower.

    Figure 5-7 shows the location of the Graphics Tower power switch and power indicator. The switch is "ON" when the side with the "1" is pushed in.

    3. Turn on the system unit.
