Notes: 1) Do not set the heat sink down after you remove the protective film. Thermal grease Heat sink 2) Do not touch the thermal grease on the bottom of the heat sink. Touching the thermal grease will contaminate it. If the thermal grease on the microprocessor or heat sink becomes contaminated, contact your service technician. b. Align and place the heat sink on top of the microprocessor (grease side down) in the retention bracket. Press firmly on the heat sink. c. Secure the heat sink to the microprocessor by tightening the captive screws. Alternate between the two captive screws in the heat sink while tightening them. Attention: Alternate the tightening of the two captive screws to prevent damage to the microprocessor. Ensure that the screws are completely tightened (until they stop); otherwise, damage to the microprocessor will occur. 10. Close the cover on the air-baffle assembly. 11. If you have other options to install or remove, do so now; otherwise, go to "Installing the server bezel and left-side cover (tower model)" on page 100 or "Installing the server bezel and top cover (rack configuration)" on page 103. Replacing a hot-swap power supply Some models of your server come with two hot-swap power supplies. You do not need to turn off the server to replace a hot-swap power supply, but you must replace only one power supply at a time.
