Install the voltage regulator modules (VRMs) 12 included in the microprocessor kit: a. Determine the connectors where the VRMs are to be installed. See Table 15 on page 372. The microprocessor upgrade kit comes with two VRMs. You might need to install only one, depending on the number of microprocessors in the server. b. 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. c. 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" on page 376. 4-way Xeon upgrade installation 375
