You can install, remove, and replace the system processor modules in the IBM Power System E950
(9040-MR9) server.
Removing and replacing the system processor module in the 9040-MR9
Find information about removing and replacing a system processor module in the IBM Power System
E950 (9040-MR9) server.
If your system is managed by the Hardware Management Console (HMC), use the HMC to repair a part in
the system. For instructions, see Repairing a part by using the HMC (www.ibm.com/support/
knowledgecenter/POWER9/p9haj/p9haj_hmc_repair.htm).
If you do not have an HMC, complete the steps in the following procedures to remove and replace a
system processor module.
Preparing the 9040-MR9 system to remove and replace a system processor module
To prepare the system to remove a system processor module, complete the steps in this procedure.
Before beginning this procedure, ensure that you have these items on hand:
• System processor module
• Thermal interface material (TIM)
• Tweezers
• Putty knife
• Heat sink
• 4MM T-handle Allen wrench
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. Label and disconnect the power source from the system by unplugging the power cords from the
system.
Notes:
• This system might be equipped with two or more power supplies. If the removing and replacing
procedures require the system power to be turned off, ensure that all power sources to the system
are disconnected.
• The power cord (B) is fastened to the system with a hook-and-loop fastener (A). If you are placing
the system in a service position after you disconnect the power cords, ensure that you unstrap the
fastener.
