!ATTENTION: Make sure you understand the anti-static environment.

The processor is shipped in a static-shielded container to guard against

electrostatic damage. Electrostatic discharge can damage integrated

circuits or semiconductors in the processor module if you touch

backplane connector pins. It can also damage the module when you set

configuration plugs or switches inside the module. Avoid electrostatic

damage by observing the following precautions.

• Remain in contact with an approved ground point while handling the

module (by wearing a properly grounded wrist strap).

• Do not touch the backplane connector or connector pins.

• When not in use, keep the module in its static-shielded container.
