Route the signal cables from the drive backplane over the blue adapterretention bracket as shown in the following illustration.SAS/SATA RAIDriser-cardConnector fordrive bays 4 - 5signal cableConnector fordrive bays 0 - 3signal cableServeRAID-MR10iadapter14. Take the signal cable that is attached to the drive backplane for drive bays 0through 3 and connect it to the SAS/SATA RAID adapter connector that isclosest to the power-supply cage. Connect the other signal cable so that it isattached to the drive backplane for drive bays 4 and 5 and connect it to theother connector on the adapter.Note: When you restart the server, you are prompted to import the existingRAID configuration to the new ServeRAID adapter.If you have other devices to install or remove, do so now. Otherwise, go to“Completing the installation” on page 85.Installing a second microprocessor and heat sinkThe following notes describe the type of microprocessor that the server supportsand other information that you must consider when you install a microprocessor andheat sink:v The server supports up to two Intel Xeon dual-core or quad-coremicroprocessors. See http://www.ibm.com/servers/eserver/serverproven/compat/us/ for a list of supported microprocessors.v Do not mix dual-core and quad-core microprocessors in the same server.v The upgrade of microprocessors are not supported on this server. For example, ifthe server came with a 2.0 GHz microprocessor, you cannot upgrade themicroprocessor to a 2.3 GHz microprocessor, it is not supported.v The first microprocessor must always be installed in microprocessor socket 1 onthe system board.v When one microprocessor is installed, a heat sink filler is not required formicroprocessor socket 2, however, the microprocessor 2 air baffle and the DIMMair baffle must be installed to provide proper system cooling.v Do not remove the first microprocessor from the system board when you installthe second microprocessor.v When you install the second microprocessor, you must also install additionalmemory. See “Installing a memory module” on page 52 for details about theinstallation sequence.Chapter 2. Installing optional devices 73
