Before You Begin
Before you begin, please review the following cautions, warnings, and general
guidelines.
Warning
Be sure that power to the system is turned off and unplugged.
All voltage is removed only when the power cords are
unplugged.
■ Avoid excessive vibration and shock. Dropping an electronic component can cause
serious damage.
■ Do not disconnect or remove parts other than those specified in the procedure.
■ Do not touch I/O connector pins.
■ All screws are Phillips-head, unless otherwise specified.
■ On completion of any assembly or reassembly, perform a power-on test. If a fault
occurs, verify that the assembly or reassembly was performed correctly. If the
problem persists, see “Solving Problems” on page 264.
Static Precautions
An electrostatic discharge (ESD) can damage disk drives, option boards, and other
components. You can provide some ESD protection by wearing an anti-static wrist
strap attached to chassis ground when handling system components.
Electronic devices can be easily damaged by static electricity. To prevent damage, keep
them in their protective packaging when they are not installed in your system.
