Removing and replacing a system processor module in the 9183-22X system
Find information about removing and replacing a system processor module in the IBM Power System
IC922 (9183-22X) server.
Removing a system processor module from the 9183-22X system
To remove a system processor module, complete the steps in this procedure.
Before you begin
Power off the system and place it in the service position. For instructions, see “Preparing the 9183-22X
system to remove and replace internal parts” on page 146.
About this task
As part of the system processor module replacement, the heat sink is removed. When the heat sink is
removed from the system processor module, the thermal interface material (TIM) is typically adhered to
the heat sink. Unless damaged, the TIM that is adhered to the heat sink can be reused. If the TIM is
damaged, do not reuse the removed heat sink. Before you begin the processor removal and replacement
procedure, ensure that you have a spare TIM and heat sink on hand.
Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is
completed, and if applicable, until the service access cover is replaced.
Attention:
• 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.
• 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.
• 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. If at any point in this service process you move away from the
system, it is important to again discharge yourself by touching an unpainted metal surface for
at least 5 seconds before you continue with the service process.
2. Open the packaging of the new system processor module, and place the cover upside down next to the
tray, as shown in the following figure. The cover is used for the system processor module that you are
replacing.
