!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.
