Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
Attention:
v Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to
an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging
your hardware.
v When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is
used for static control. It does not increase or decrease your risk of receiving electric shock when
using or working on electrical equipment.
v If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging and
installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of
5 seconds.
2. Open the packaging of the new system processor module, and place the cover upside down next to
the tray, as shown in Figure 154. The cover is used for the system processor module that you are
replacing.

3. Remove the heat sink from the system processor module:
a. Loosen the heat sink actuation screw by turning the supplied hex key counterclockwise (A).
Loosen the screw until it moves freely. See Figure 155 on page 136.
b. Grip the heat sink (B) on opposing sides and remove the heat sink by lifting it upward. Set the
heat sink aside with the module side facing upward.
Note: If you plan to remove dust or debris from the heat sink, this operation must be done in
another room that is greater than 7.6 m (24.9 ft) away from the work area.
