Installing Microprocessors For additional information about microprocessor speeds, clock frequencies, and jumper settings, see Chapter 7, "Server Records and Specifications" on page 193. CAUTION: If your server has been operating, the heat sinks on the installed microprocessor will be hot. You can avoid getting a burn while removing an existing microprocessor or installing an additional one, if you let the components cool for 10 minutes before continuing with the procedures described in this section. Notes: 1. The microprocessor in your server comes with an attached heat sink. The microprocessor plugs into the primary microprocessor socket on the system board and is stabilized with a plastic bracket attached to the system board. The type of heat sink in your server might be different from the heat sink shown in this section. 2. When you add a second microprocessor, it must operate at the same speed as the primary microprocessor. For information about the appropriate switch settings, see "Setting the Microprocessor Speed Switches" on page 209, or see the label inside the server cover. To locate the microprocessor switch area of the system board, find the rocker switches section of the system-board illustration. See "System Board Illustration" on page 203. Chapter 4.
