a. Turn the DIMM so that the DIMM keys align correctly with the connector onthe system board.Attention: To avoid breaking the retaining clips or damaging the DIMMconnectors, handle the clips gently.b. Insert the DIMM by pressing the DIMM along the guides into the connector.Make sure that the retaining clips snap into the closed positions.Important: If there is a gap between the DIMM and the retaining clips, theDIMM has not been properly installed. In this case, open the retaining clipsand remove the DIMM; then, reinsert the DIMM.8. If you have other options to install or remove, do so now; otherwise, go to“Completing the installation” on page 52.Installing an additional microprocessorThe blade server comes with one or two microprocessors installed on the systemboard. The blade server supports two microprocessors. With two microprocessors,the blade server can operate as a symmetric multiprocessing (SMP) server. WithSMP, certain operating systems and application programs can distribute theprocessing load between the microprocessors. If the blade server comes with onemicroprocessor, you can install a second microprocessor. To use SMP, obtain anSMP-capable operating system. For a list of supported operating systems and otheroptions, go to http://www.ibm.com/pc/us/compat/.Attention: To ensure proper blade server operation when you install a secondmicroprocessor, observe the following precautions:v Always install microprocessors that have the same cache size and type, thesame clock speed, and identical internal and external clock frequencies (includingsystem bus speed).v Make sure that the microprocessor with the lowest feature set is the startup(bootstrap) microprocessor installed in the microprocessor 1 socket (locationU66).Notes:1. For a list of microprocessors supported by the HS20 blade server, go to theServerProven list at http://www.ibm.com/pc/us/compat/.2. Thoroughly review the documentation that comes with the microprocessor, sothat you can determine whether you need to update the blade server BIOScode. The latest level of BIOS code for the blade server is available fromhttp://www.ibm.com/pc/support/ on the World Wide Web.3. The microprocessor sockets in this server contain built-in termination for themicroprocessor bus; therefore, no terminator card is required if a secondmicroprocessor is not installed in microprocessor socket 2. However, for properairflow, this socket must contain a microprocessor heat-sink filler, sometimescalled a microprocessor baffle.4. The microprocessor speeds are automatically set for this server; therefore, youdo not need to set any microprocessor frequency-selection jumpers or switches.Figure 20 on page 42 depicts the installation of a second microprocessor on thesystem board.Chapter 5.
