Removing a system processor module from the 8335-GTW or 8335-GTX system

To remove a system processor module, complete the steps in this 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 Figure 1. The cover is used for the system processor module that you are replacing.

   

3. Remove the air baffles (A) and (B) as shown in Figure 2.
   Carefully move the baffles around the hoses.

   

4. Remove the cold plate from the system processor module.
   1. Apply light pressure downward on the cold plate. Loosen the retainer screw of the system processor module cold plate by turning the supplied hex key counterclockwise. Loosen the screw until it moves freely.
      See Figure 3.

      

   2. Lift the cold plate (A) straight up off the system processor module and attach the protective cover (B) to the cold plate as shown in Figure 4.

      

   3. Move the cold plate and cover off to the side, away from the system processor module.
5. Using tweezers, carefully remove the TIM from the top of the system processor module and place it in a clean, dry area as shown in Figure 5.
   The TIM can tear easily.

   

6. Remove dust and debris from the system processor module area.
   If dust or debris is present, use the supplied air pump to clean the system processor module area. Blow small bursts of air from the center toward the sides of the system processor module as shown in Figure 6. If your air pump is not assembled as shown in Figure 6, fasten the tip onto the bulb.

   

7. Prepare the system processor module for removal.
   1. Open the latches that hold the system processor module in the supplied removal tool (A). Push down on the ring (B) while pressing in on the tabs (C).
      See Figure 7.

      

   2. Lower the tool over the system processor module while ensuring that the two guide pins (A) insert into the alignment holes (B) on each side of the tool.
      See Figure 8.

      

   3. With the removal tool sitting on top of the system processor module, push down on the ring (A) to close the latches (C) and lock the system processor module into the tool. Make sure that both of the tool jaws are locked on the system processor module.
      See Figure 9.

      

8. Holding the outside of the tool, lift the tool and system processor module from the socket. Place them at an angle in the top cover of the system processor module packaging, as shown in Figure 10.
   Note: Set the tool and system processor module at an angle on the top cover of the system processor module packaging. That makes the module easier to pick up and place into the package.

   

9. Open the latches that hold the system processor module in the supplied removal tool (A). Push down on the ring (B) while pressing in on the tabs (C).
   See Figure 11.
