 | Tip: If the cover is difficult to raise, check the locking levers of your drives to be sure they are fully locked. The levers should be pushed all the way to the right. |
Wear the wrist strap to prevent the flow of static electricity, which can damage the board.
 | Caution: The components inside the Indigo2 IMPACT workstation are extremely sensitive to static electricity; you must wear the wrist strap while replacing parts inside the workstation. |
To attach the wrist strap, follow these steps:
Unwrap the first two folds of the band and wrap the exposed adhesive side firmly around your wrist.
Unroll the rest of the band and peel the liner from the copper foil at the opposite end.
Attach the copper foil to a convenient and exposed electrical ground, such as a metal part of the Indigo2 IMPACT workstation.
To remove the Indigo2 Solid IMPACT, High IMPACT, or Maximum IMPACT graphics boards, follow these steps:
Make sure the wrist strap is attached to a metal part of the chassis.
Move the workstation or position yourself so that you are facing the expansion slots, as shown in Figure 5-7.
Open the metal panel in front of the expansion slots by pulling up on the panel and lowering it.
Caution: The heat sinks in your Indigo2 IMPACT workstation become hot when the workstation is running. Take a coffee break for a few minutes while the graphics boards cool before you begin working with them.
Note: Illustrations show the High IMPACT board set, but are true for the Solid IMPACT graphics board, the High IMPACT and Maximum IMPACT graphic board sets. Note: Any option boards and your Indigo2 Solid IMPACT, Indigo2 High IMPACT, or Maximum IMPACT board set must be replaced in the same slots. Remove the screws attaching the board set to the workstation slots as shown in Figure 5-8. The number of screws to be removed equals the number of boards you are removing.
The screws are located on the metal extension on the left side of each board.
Loosen each screw with the Phillips screwdriver.
Unscrew and remove the screws with your hand.
The screws are very small. If you drop a screw into the chassis, retrieve it to prevent shorting the system.
Note: You will have to remove one screw from a Solid IMPACT graphics board and three screws from a Maximum IMPACT graphics board set. Remove the retention pin from the workstation.
Grasp the retention pin on the right front end of the board set and pull it up and off. See Figure 5-9.
