Upgrading the system
Certain components of the server are upgradeable such as the drives,
the CPU, the memory, and the expansion cards. However, for safety
purposes, we do not recommend that you perform these upgrades
yourself. If you want to replace or upgrade any of these components,
contact your dealer or a qualified service technician for assistance.
Important: Observe the installation precautions described in the
subsequent section when installing or removing a server
component.
Installation precautions
Before you install any server component, we recommend that you read
the following sections. These sections contain important ESD
precautions along with preinstallation and post-installation
instructions.
ESD precautions
Electrostatic discharge (ESD) can damage the processors, motherboard,
disk drives, expansion boards, or other components. Always observe
the following precautions before you install a server component:
1 Do not remove a component from its protective packaging until
you are ready to install it.
2 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.
Preinstallation instructions
