26 3 System upgrades 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, mainboard, 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.
