7. Pull out and lift up the release lever and remove the microprocessor from the connector. Store the microprocessor in a static-protective package for possible future use. 8. To install a new microprocessor, continue with step 4 in "Microprocessor installation." Microprocessor installation Complete the following steps to install 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 information" on page 103. 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 and "System board internal cable connectors" on page 38 for instructions. 4. Install the microprocessor: a. Touch the static-protective package containing the new microprocessor to any unpainted metal surface on the server; then, remove the microprocessor from the package. b. Pull out and lift up on the microprocessor-release lever to unlock the microprocessor connector. c. Arrange the microprocessor over the microprocessor connector as shown in the following illustration. Carefully press the microprocessor into the connector.
