4. Grasp the handles, and slide the DPC straight out of the card cage halfway.
5. Place one hand around the front of the DPC and the other hand under it to support it.
Slide the DPC completely out of the chassis, and place it on the antistatic mat or in
the electrostatic bag.
CAUTION: The weight of the DPC is concentrated in the back end. Be
prepared to accept the full weight—up to 13.1 lb (5.9 kg)—as you slide the
DPC out of the chassis.
When the DPC is out of the chassis, do not hold it by the ejector handles,
bus bars, or edge connectors. They cannot support its weight.
Do not stack DPC on top of one another after removal. Place each one
individually in an electrostatic bag or on its own antistatic mat on a flat,
stable surface.
