Prerequisites
CAUTION: The internal components of the system are susceptible to
mechanical and electrostatic shock. To prevent such damage from
occurring, observe the following precautions during the installation
procedure.
• Stand on a static-free mat
• Wear a static-grounding wrist strap to ensure that any accumulated
electrostatic charge discharges from your body to ground. Attach the
static-grounding wrist strap by following the instructions on the pack-
age that contains the strap. Be sure to attach one end of the strap to the
system chassis.
• Handle system and upgrade kit components carefully to prevent dam-
