Before you begin
Before you begin the removal and replacement procedure, ensure that you have the following items:
• Service representative tool kit (including a 4 mm hex driver, flat head screwdriver, hex key, and 5.5 mm

• System backplane kit
• 4 mm ball-end hex driver
Procedure
1. Identify the part and the system that you are working on. For instructions, see Identifying a
part (www.ibm.com/support/knowledgecenter/POWER9/p9haj/sal.htm).
Use the blue identify LED on the enclosure to locate the system. Ensure that the serial number of the
system matches the serial number to be serviced.
2. Stop the system. For instructions, see Stopping a system (www.ibm.com/support/knowledgecenter/
POWER9/p9haj/crustopsys.htm).
3. If applicable, open the rack door at the rear of the system.
4. 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
