Depending on the model, your server might come with one or two microprocessors. For server models with one microprocessor, the microprocessor is installed in the microprocessor socket 1 and the microprocessor socket 2 is protected by a plastic socket cover. You can purchase a microprocessor option kit from Lenovo and install the second microprocessor to expand system capabilities. CAUTION: Turn off the server and wait three to five minutes to let the server cool before removing the server cover. Before you begin, print all the related instructions or ensure that you can view the PDF version on another computer for reference. Notes: • Ensure that you install the correct type of microprocessor option your server supports. See "Memory module installation rules" on page 81. When two microprocessors are installed, both must have the same core voltage and core speed. • Use any documentation that comes with the microprocessor option kit and follow those instructions in addition to the instructions in this topic. • Your microprocessor, socket, and socket cover might look slightly different from the illustrations in this topic. To install the second microprocessor, do the following: 1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all power cords from electrical outlets and disconnect all cables that are connected to the server. 2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat, clean, and static-protective surface. See the Rack Installation Instructions that comes with the server. 3. Remove the server cover. See "Removing the server cover" on page 75. 4. Remove the cooling shroud. See "Removing and reinstalling the cooling shroud" on page 79. 5. Locate the microprocessor socket 2 on the system board. See "System board components" on page 38. Chapter 6.
