Installation precautions
Before you install any server component, we recommend that you read
the following sections. These sections contain important ESD
precautions along with pre-installation and post-installation
instructions.
ESD precautions
Electrostatic discharge (ESD) can damage the processor, disk drives,
expansion boards, mainboards, memory modules and other server
components. 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.
Pre-installation instructions
Perform the steps below before you open the server or before you
remove or replace any component:
Warning! Failure to properly turn off the server before you start
installing components may cause serious damage. Do not attempt
the procedures described in the following sections unless you are
a qualified service technician.
1 Turn off the system and all the peripherals connected to it.
2 Unplug all cables from the power outlets.
3 Disconnect all telecommunication cables from their ports.
4 Place the system unit on a flat, stable surface.
