7. Install the VRM that comes with the microprocessor kit in the slot adjacent to the microprocessor you are replacing or installing. Some microprocessor options contain a VRM with a clip to secure the VRM in the slot. This clip is not needed for installation and can be discarded. a. If you are replacing a failed VRM: 1) Verify that you have selected the correct VRM to be replaced. The LED next to the failing VRM will be lit. 2) Grasp the VRM at both upper corners and lift it out of the slot. Figure 68. Microprocessor VRM b. Holding the new VRM by the upper corners, plug it firmly into the slot. 8. If necessary, remove microprocessor baffle from the microprocessor socket. Keep the microprocessor baffle for possible future use. 9. Touch the static-protective package containing the new microprocessor to any unpainted metal surface on the server; then, remove the microprocessor from the package. 10. Install the microprocessor: Important: When installing Intel Xeon DP microprocessors, you must install them in the following order: socket 1 then socket 4. When installing Intel Xeon MP microprocessors, you must install them in the following order: sockets 1, 2, 3, and then 4. a. Remove the protective label from the microprocessor socket. b. Rotate the locking lever on the microprocessor socket from its closed and locked position until it stops or clicks in the fully open position (approximately 135° angle), as shown. Attention: You must ensure that the locking lever on the microprocessor socket is in the fully open position before you insert the microprocessor in the socket. Failure to do so might result in permanent damage to the microprocessor, microprocessor socket, and system board. Chapter 4. Installing options 119
