11.Install the VRM that is included in the microprocessor kit. Attention: Use of other VRMs might cause the server to overheat. a. Center the VRM over the appropriate VRM connector:
1)If you installed the microprocessor in connector U11, press down on the latches on either side of connector J12, and install the VRM in connector J12.
2)If you installed the microprocessor in connector U12, press down on the latches on either side of connector J42, and install the VRM in connector J42.
Note: If the server is a
J42 after you reinstall the support bracket assembly.
b.Make sure that the VRM is oriented and aligned correctly.
c.Press the VRM into the connector.
Note: If you remove the microprocessor later, remember to install the terminator card in the appropriate microprocessor connector and to remove the VRM from the appropriate VRM connector.
12.If you have other options to install or remove, do so now; otherwise, replace the support bracket assembly; then, go to “Installing the cover” on page 83.
Removing a microprocessor
To remove a microprocessor, do the following:
Note: Do not use any tools when removing the microprocessor; however, you will need a small,
Attention: When you handle electrostatic discharge (ESD) sensitive devices, take precautions to avoid damage from static electricity. For details on handling these devices, see “Handling electrostatic
1.Review the safety precautions in Statement 1 and Statement 5 in “Safety information” on page 133.
2.Turn off the server and peripheral devices, and disconnect all external cables and power cords; then, remove the cover (see “Removing the side cover” on page 59 for details).
3.Carefully remove the support bracket assembly from the server (see “Removing the support bracket assembly” on page 61). Store the cover and the support bracket assembly in a safe place.
4.If the server is a
Note: Remember to reinstall this VRM after you reinstall the support bracket assembly, unless you are not replacing the microprocessor.
5.If you are removing a microprocessor that has a speed lower than 933 MHz:
a.Push down and back on the lever to remove the retainer (clip) from the heat sink.
b.Firmly grasp the heat sink and lift it off the microprocessor. Store the heat sink in a safe, clean place with the bottom side up. The thermal material on the heat sink must stay clean if you intend to reuse the heat sink in the future.
c.Continue with step 7 on page 83.
6.If you are removing a microprocessor that has a speed of 933 MHz or higher:
