Installation precautions
Before you install any server component, it is recommended that you
read the following sections first. These sections contain important ESD
precautions along with pre-installation and post-installation
procedures.
ESD precautions
Electrostatic discharge (ESD) can damage static-sensitive hardware
components, such as the processor, disk drives, and the system board.
Always observe the following precautions before you install a server
component:
•
Do not remove a component from its protective packaging until
you are ready to install it.
• Do not touch the component pins, leads, or circuitry.
• Components with a Printed Circuit Board (PCB) assembly should
always be laid with the assembly-side down.
• Wear a wrist grounding strap and attach it to a metal part of the
server before handling components. If a wrist strap is not
available, maintain contact with the server throughout any
procedure requiring ESD protection.
• Keep the work area free of nonconductive materials, such as
ordinary plastic assembly aids and foam packing.
