If the server comes with one microprocessor, you can install a second microprocessor. v Both microprocessors must have the same cache size and type, front-side bus frequency, and clock speed. Microprocessor internal and external clock frequencies must be identical. v When you install a microprocessor in microprocessor connector 2, you must also install the voltage regulator module (VRM), which comes with the microprocessor, in the VRM connector. v Read the documentation that comes with the microprocessor to determine whether you must update the basic input/output system (BIOS) code for the server. To download the most current level of BIOS code and many other code updates for your server, complete the following steps: 1. Go to http://www.ibm.com/systems/support/. 2. Under Product support, click System x. 3. Under Popular links, click Software and device drivers. 4. Click System x3650 to display the matrix of downloadable files for the server. v (Optional) Obtain an SMP-capable operating system. For a list of supported operating systems and optional devices, see http://www.ibm.com/servers/eserver/ serverproven/compat/us/. v To order additional microprocessor optional devices, contact your IBM marketing representative or authorized reseller. v The microprocessor speeds are automatically set for this server; therefore, you do not have to set any microprocessor frequency-selection jumpers or switches. v If you have to replace a microprocessor, call for service. v If the thermal-grease protective cover (for example, a plastic cap or tape liner) is removed from the heat sink, do not touch the thermal grease on the bottom of the heat sink or set down the heat sink. v Do not remove the first microprocessor from the system board to install the second microprocessor. See "System-board optional-device connectors" on page 17 for the location of the microprocessor connectors and the VRM connector. The following illustration shows how to install the second microprocessor on the system board. Chapter 2. Installing optional devices 63
