v Read "Handling electrostatic discharge-sensitive devices" on page 112. Complete the following steps to remove the processor board: 1. Shut down the operating system, and turn off the blade server (see "Turning off the blade server" on page 7). 2. Remove the blade server from the BladeCenter unit (see "Removing the blade server from the BladeCenter unit" on page 39). 3. Remove the blade server bezel assembly (see "Removing the blade server bezel assembly" on page 42). 4. Remove the blade server cover (see "Opening the blade server cover" on page 40) or SCSI storage expansion unit (see "Installing a SCSI storage expansion unit" on page 51). 5. Pivot the I/O board tray to the upward position. 6. Remove all components (see the appropriate installation instructions and reverse the steps), and place them on a static-protective surface for reinstallation. Notes: a. A microprocessor assembly comes with a new heat sink. b. A processor board does not come with a heat sink. When replacing the processor board and reinstalling an existing microprocessor, be sure to re-install the heat sink (see "Thermal grease" on page 72). 7. Remove the six screws that secure the heat-sink retention bracket to the processor board and the blade server chassis, and put the screws and the module in a safe place. 8. Remove the heat-sink retention bracket from the blade server. Chapter 5. Service replaceable units 73
