Installing a Microprocessor Kit



Installing a Microprocessor Kit

The following tables show the order in which microprocessors and VRMs must be installed.

Note: A terminator card must be installed in each microprocessor connector that does not contain a microprocessor.


ONE Microprocessor installed in J1:

J13
(VRM 2)
J14
(VRM 3)
J16
(VRM 4)
J17
(VRM 5)

Refer to the following illustrations of the processor housing and processor board that come with this option while you perform the steps in this procedure.

 


1 Processor housing cover
2 Quarter-turn fasteners

 

3 Latches
4 Second installed microprocessor (CPU or processor 4)
5 First installed microprocessor (CPU or processor 1)
6 Microprocessor connector 1 (J1)
7 Microprocessor connector 2 (J2)
8 Microprocessor connector 3 (J3)
9 Microprocessor connector 4 (J4)
10 Terminator card
11 VRM connectors 5 (J17) and 6 (J18)
12 VRMs for second microprocessor (VRMs 5 and 6)
13 VRMs for first microprocessor (VRMs 1 and 2)

Complete this procedure to install a microprocessor in the processor housing that comes with this option.
  1.  Determine the connectors where the microprocessor  and VRMs are to be installed. See the tables on the top of this chapter.
  2.  Turn the quarter-turn fasteners 2 and remove the  processor housing cover 1.
  3.  Pull on the fasteners and remove the fan assembly.
  4.  If the microprocessor connector 9 contains a  microprocessor terminator card 10, remove the  terminator card from the microprocessor connector.
  5.  Install the microprocessor:

    1.  Touch the static-protective package containing  the new microprocessor to any unpainted  metal  surface on the processor housing; then, remove  the microprocessor from the package.
    2.  Hold the microprocessor 4 by the open latches 3, and center the microprocessor over the  microprocessor connector 9.

       - Attention: - Make sure  the microprocessor is oriented  and aligned correctly before you try to close the latches.

    3.  Press the microprocessor into the connector and  carefully close the latches 3 to seat the  microprocessor in the connector.

  6.  Set the microprocessor core-ratio selection jumper  block for the correct core ratio.

     - Attention: -  If the microprocessor bus-to-core ratio is  incorrect, system-board components will overheat  and component damage might occur. Be sure  that the microprocessor core-ratio selection is properly set.

     
    39(J31) - 42(J28) Microprocessor core-ratio-selection:

  7.  Install the voltage regulator modules (VRMs) 12  included in the microprocessor kit:

    1.  Determine the connectors where the VRMs are  to be installed. See the tables on the top of this chapter.  The microprocessor upgrade kit comes with two  VRMs. You might need to install only one,  depending on the number of microprocessors in the server.
    2.  Center the VRM 12 over the connector 11.  Make sure that the VRM is oriented and aligned  correctly; then, press the VRM into the connector.
    3.  Repeat the preceding step for the second VRM, if needed.

    Note:  If you need to install only one VRM, store  the remaining VRM in a safe place to use as a replacement.

  8.  Go to Installing memory-modules.
