Installing an additional microprocessor The following notes describe information that you must consider when installing a microprocessor: v The voltage regulators for microprocessors 1 and 2 are integrated on the microprocessor board; the VRMs for microprocessors 3 and 4 come with the microprocessor options and must be installed on the microprocessor board. v Each microprocessor socket must be populated with either a microprocessor baffle or a heat sink and microprocessor to ensure the server operates properly. v Install the microprocessors in the order shown in the following illustration. If you install the microprocessors in the wrong order, the server will not start. 1 2 4 3 To install an additional microprocessor, complete the following steps: 1. Read the safety information that begins on page v and "Installation guidelines" on page 7. 2. Turn off the server and peripheral devices, and disconnect the power cords and any USB cable that might be connected to the USB port on the front of the server. Remove the server cover and bezel. Attention: When you handle static-sensitive devices, take precautions to avoid damage from static electricity. For details about handling these devices, see "Handling static-sensitive devices" on page 8. Chapter 2. Installing options 15
