IBM manual Removing a microprocessor, IBM xSeries 220 User’s Reference

(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 your server is a hot-swap model, reinstall the VRM in connector 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 side cover” on page 60.

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, flat-blade screwdriver to remove the fan-sink retainer (clip).

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 static-sensitive devices” on page 31.

1.Review the safety precautions in Statement 1 and Statement 5 in “Safety information” on page 32.

2.Turn off the server and peripheral devices, and disconnect all external cables and power cords; then, remove the side cover (see “Removing the side cover” on page 38 for details).

3.Carefully remove the support bracket assembly from the server (see “Removing the support bracket assembly” on page 39). Store the cover and the support bracket assembly in a safe place.

4.If your server is a hot-swap model, press down on the latches on either side of connector J42, and remove the VRM from connector J42. (See “System-board option connectors” on page 28 for connector location.)

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 59.

6.If you are removing a microprocessor that has a speed of 933 MHz or higher:

a.Insert a small, flat-blade screwdriver into the tab on the fan-sink retainer (clip).

b.Press down and in with the screwdriver handle to remove the fan-sink retainer from the fan sink.

c.Firmly grasp the fan sink and lift it off the microprocessor. Store the fan sink in a safe, clean place with the bottom side up. The thermal material on the fan sink must stay clean if you intend to reuse the fan sink in the future.
