v To ensure proper server operation when you install an additional microprocessor,use microprocessors that have the same QuickPath Interconnect (QPI) linkspeed, integrated memory controller frequency, core frequency, power segment,internal cache size, and type.v Mixing microprocessors of different stepping levels within the same server modelis supported.v When mixing microprocessors with different stepping levels within the sameserver model, you do not have to install the microprocessor with lowest steppinglevel and features in microprocessor socket 1.v Both microprocessor voltage regulator modules are integrated on the systemboard.v If you have to replace a microprocessor, call for service.v Read the documentation that comes with the microprocessor, so that you candetermine whether you have to update the server firmware. To download thelatest level of the server firmware and 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 IBM System x3550 M2 to display the matrix of downloadable files forthe server.v The microprocessor speeds are automatically set for this server; therefore, youdo not have to set any microprocessor frequency-selection jumpers or switches.v If the thermal-grease protective cover (for example, a plastic cap or tape liner) isremoved from the heat sink, do not touch the thermal grease on the bottom ofthe heat sink or set down the heat sink. For details, see the information aboutthermal grease in the Problem and Determination Service Guide.Note: Removing the heat sink from the microprocessor destroys the evendistribution of the thermal grease and requires replacing the thermalgrease.v To order an additional optional microprocessor, contact your IBM marketingrepresentative or authorized reseller.To install an additional microprocessor and heat sink, complete the following steps:1. Read the safety information that begins on page vii and “Installation guidelines”on page 46.2. Turn off the server and peripheral devices and disconnect the power cords andall external cables (see “Turning off the server” on page 33).Attention: When you handle static-sensitive devices, take precautions toavoid damage from static electricity. For details about handling these devices,see “Handling static-sensitive devices” on page 48.3. Remove the cover (see “Removing the cover” on page 49).4. Locate microprocessor socket 2 on the system board.5. Remove the microprocessor 2 air baffle (see “Removing the DIMM air baffle” onpage 51).6. Rotate the heat-sink release lever to the fully open position and lift the heat-sinkfiller off the microprocessor socket.7. Install the microprocessor:a. Press down and out on the release lever on microprocessor socket 2 and liftup the microprocessor release lever until it stops in the fully open position.74 IBM System x3550 M2 Types 4198 and 7946: Installation and User’s Guide
