Captive screws Heat sink Microprocessor VRM Microprocessor release lever Attention: v A startup (boot) processor must always be installed in socket J7 on the system board. v To ensure proper server operation when you install an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical. Complete the following steps to install an additional microprocessor: 1. Read the safety information beginning on page v and "Installation guidelines" on page 7. 2. Turn off the server and peripheral devices, and disconnect the power cords and all external cables, if necessary; then, remove the top cover. 3. Remove the air baffle. Chapter 2.
