The anti-static wrist strap, provided with the GT Graphics Subsystem, provides grounding between your body and the system unit chassis. Boards and modules can be damaged by harmful electrical charges if you do not wear the wrist strap. The wrist strap must be attached to your wrist and to the chassis before handling any of the system unit boards.
To attach the wrist strap:
Make sure the adhesive side is against your skin.
Figure 3-2 Attaching the Wrist Strap
Attach this adhesive copper strip to the metal case of the power supply in the system unit.
Note - Normally, the SPARCstation is shipped without any frame buffer board installed. If your system was shipped with a frame buffer board, the board must be removed before proceeding with the installation.
Remove the frame buffer board, as follows:
Caution -
The frame buffer board is most likely installed in SBus slot 1 or 2. See Figure 3-3. This board will have a monitor connector protruding through the system unit rear panel.
Figure 3-3 Locate the GX or Frame Buffer Board
Make sure that the board mounting plate unhooks from the slots on the system unit back panel.
When you are through installing the GT SBus Adapter Board, you can place the unused GX or frame buffer board in the anti-static envelope that the GT SBus Adapter Board came in.
Proceed to "Install the GT SBus Adapter Board" on page 21.
If you are upgrading an existing SPARCstation, you will not have to perform this step. Proceed to "Install the GT SBus Adapter Board" on page 21.
If this is not an upgrade, remove the rear panel filler plate from one of the SBus slots from the inner surface of the back panel of your system unit, as shown in Figure 3-4. The GT SBus Adapter Board will work in any one of the three slots (see the note below).
Caution -

Caution -
See Figure 3-5. The GT SBus Adapter Board may be installed into any one of the three slots, with the exception noted above.
Make sure that the mounting plate on the GT SBus Adapter Board hooks into the slot on the system unit back panel. The mounting slots are above the rectangular openings in the back of the panel. See Figure 3-6.
See Figure 3-6.

Replace the system unit top cover as follows:
Caution -
Hold the cover at an angle of 30 degrees relative to the chassis and gently guide the plastic tabs on the cover into the tab slots on the front of the chassis. Continue to hold the cover with your hands. See Figure 3-7.

Slowly lower the cover onto the chassis making sure that the protector loop clears the disk drive and seats into the protector loop slot on the bottom of the chassis.
Tighten the two screws with a Phillips screwdriver.
