Before You Begin
CAUTION!
BEFORE REMOVING THE SERVER COVER, DISCONNECT ALL POWER. UN-
PLUG THE AC POWER CORD; DISCONNECT ALL PERIPHERALS, AND ALL
LAN LINES.
Make sure you have a stable, clean working environment. Dust and dirt can get into computer components and
cause a malfunction. Many of the screws on the server are different sizes; use containers to keep screws and small
components separated.
Adequate lighting and proper tools can prevent you from accidentally damaging internal components. Most of the
following procedures require only a few simple tools, including the following:
•
A Philips screwdriver
•
A flat-tipped screwdriver
•
A set of jewelers screwdrivers
•
A grounding strap
•
An anti-static pad
Most of the electrical connections can be disconnected by using your fingers. It is recommended that you do not
use needle-nosed pliers to disconnect connections as these can damage the soft metal or plastic parts of the con-
nectors.
Before working on internal components, make sure that the server power is off. Ground yourself before touching
any internal components, by touching a metal object. Static electricity can damage many of the server’s electronic
components. Humid environments tend to have less static electricity than dry environments. A grounding strap is
warranted whenever danger of static electricity exists.
