Microprocessor orientation indicator Microprocessor Microprocessor fan-sink connector (CPUFA1) Microprocessor connector Lever Tab Fan sink Thermal tape liner Retainer Complete the following steps to remove a microprocessor. Attention: When you handle ESD-sensitive devices, take precautions to avoid damage from static electricity. For details on handling these devices, see "Handling electrostatic discharge-sensitive devices" on page 106. 1. Review the safety precautions listed in Statement 1 and Statement 5 in "Safety notices (multi-lingual translations)" on page 107. 2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then, remove the cover (see "Side cover removal" on page 42 for details). 3. Remove the support-bracket assembly and disconnect the fan cable from the connector (SYSFA1) on the system board. See "Removing the support bracket assembly" on page 45 for details. See "System board internal cable connectors" on page 38 for the location of the fan cable connector. 4. Push down and back on the retainer to remove it from the heat sink or the fan sink. Note: Allow sufficient time for the heat sink to cool, before you remove it from the microprocessor. 5. If you are removing a fan sink from the microprocessor, disconnect the fan-sink power cable from the microprocessor fan-sink connector located on the system board. See "System board internal cable connectors" on page 38 for the location. 6. Firmly grasp the heat sink and lift it off the microprocessor. 58 xSeries 200 Type 8479 and xSeries 200VL Type 8481: Hardware Maintenance Manual
