3. Use the cleaning pad to wipe the thermal grease from the bottom of the heatsink.Note: Make sure that all of the thermal grease is removed.4. Use a clean area of the cleaning pad to wipe the thermal grease from themicroprocessor; then, dispose of the cleaning pad after all of the thermal greaseis removed.5. Use the thermal-grease syringe to place 9 uniformly spaced dots of 0.02 mLeach on the top of the microprocessor. The outermost dots must be withinapproximately 5 mm of the edge of the microprocessor; this is to ensureuniform distribution of the grease.Note: If the grease is properly applied, approximately half of the grease willremain in the syringe.6. Install the heat sink onto the microprocessor as described in “Installing amicroprocessor and heat sink” on page 92.Removing the microprocessor 2 expansion boardTo remove the microprocessor 2 expansion board, complete the following steps:1. Read the safety information that begins in Safety and “Installation guidelines”on page 36.2. Turn off the server (see “Turning off the server” on page 24) and all attachedperipheral devices. Disconnect all power cords; then, disconnect all externalcables from the server.3. Carefully turn the server on its side so that it is lying flat, with the coverfacing up.Attention: Do not allow the server to fall over.4. Unlock and remove the left-side cover (see “Removing the left-side cover” onpage 39)5. Remove the air baffle (see “Removing the air baffle” on page 41)6. Remove the fan assembly (see “Removing the fan assembly” on page 42)7. Note where the cables are connected to the microprocessor 2 expansion board;then, disconnect them.422 System x3300 M4 Type 7382: Installation and Service Guide
