Removing the 8248-L4T, 8408-E8D, or 9109-RMD system processor modules

Learn how to remove the system processor modules from a server to replace a failing part or as part of another service procedure.

1. Complete the prerequisite tasks that are described in Before you begin; however, do not disconnect the power cords now.
2. If necessary, identify the system where the system processor must be replaced by using the blue LED light. The blue LED light helps to identify the system of interest in a rack or in a computer room that has many systems or rows of racks. For instructions, see Enabling enclosure indicators.
3. Stop the system or logical partition. For instructions, see Stopping the system or logical partition.
4. Disconnect the power cords:
   1. Open the rear rack door on the unit you are servicing.
   2. Identify the system unit that you are servicing in the rack.
   3. Disconnect all power cords from the unit you are servicing. See Figure 1.

5. Remove the front covers. For instructions, see Remove the front covers from the 8248-L4T, 8408-E8D, or 9109-RMD.
6. Attach the wrist strap.
   Attention:

   • Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge from damaging your hardware.
   • When using a wrist strap, follow all electrical safety procedures. A wrist strap is 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 a wrist strap 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.
7. Remove the system processor assembly. For instructions, see Removing the 8248-L4T, 8408-E8D, or 9109-RMD system processor assembly.
8. If necessary, identify the system processor modules that you must replace. For instructions, see Identifying a part.
9. Open the packaging of the new system processor module, and place the cover upside down next to the tray, as shown in Figure 2. The cover will be used for the system processor module that you are replacing.

10. Remove the heat sink:
    1. Loosen the heat-sink actuation screw by turning the supplied nut driver counterclockwise (A), as shown in Figure 3. Loosen the screw until it moves freely.
    2. Grip the heat sink (B) by the grooves on opposing sides and remove the heat sink by lifting it upward. Set the heat sink aside on an electrostatic discharge (ESD) surface with the system processor module side facing upward.
       Note: If you plan to remove dust or debris from the heat sink, this operation must be performed in another room that is greater than 7.62 m (25 ft) away from the work area.
    Figure 3. Removing the heat sink

    
11. If dust or debris is present, use an air bulb to clean by blowing small bursts of air from the center toward the sides of the system processor module, as shown in Figure 4.

12. Prepare the system processor module for removal:
    1. Using the removal tool, align the beveled corner (A) of the tool over the beveled corner of the module, as shown in Figure 5.
    2. Lower the tool over the system processor module by ensuring that the two guide pins (B) are inserted into the alignment holes on each side of the tool.
       Figure 5. Prepare the system processor module for removal

       
    3. With the removal tool (A) sitting on top of the system processor module, push down on the tool to lock the system processor module into the tool, as shown in Figure 6.
       Note: The tool drops slightly when you push down so that the jaws can grab the bottom of the system processor module.

13. Holding the outside of the tool, lift the tool and system processor module from the socket and place them at an angle in the top cover of the system processor module packaging that was opened in step 8, as shown in Figure 7.
    Note: Setting the tool and system processor module at an angle on the top cover of the system processor module packaging will make it easier to pick up and place in the packaging after you replace the system processor module.

14. Squeeze the two tabs to release the system processor module from the tool. See Figure 8.
    Note: To prevent the system processor module from falling, do not squeeze the two tabs before you place the tool on the top cover of the system processor module packaging.
