Secondary Microprocessor VRM Connectors Primary Microprocessor VRM Connectors Microprocessor Core-Frequency-Selection Switch Block (SW1) Secondary Microprocessor Connector DIMM Socket 1 DIMM Socket 2 DIMM Socket 3 DIMM Socket 4 Primary Microprocessor Connector 2. Install the microprocessor in the primary microprocessor connector. a. Touch the static-protective package containing the new microprocessor to any unpainted metal surface on the server; then remove the microprocessor from the package. b. Hold the microprocessor 1 by the open latches 3 and center the microprocessor over the microprocessor connector. c. Make sure the microprocessor is oriented and aligned correctly. d. Insert the microprocessor into the guides until it seats in the connector. Close the latches. 3. Install the two VRMs (voltage regulator modules) 9 in the primary microprocessor VRM connectors. a. Center one VRM over the connector. b. Make sure the VRM is oriented and aligned correctly. c. Press the VRM into the connector until the VRM latches snap into the locked position. d. Repeat this procedure to install the other VRM. 4. If you are installing a second microprocessor kit, complete this procedure. a. Remove the terminator card 5 from the secondary microprocessor connector 6 . b. Refer to the procedure in step 2 and install the secondary microprocessor 4 . c. Refer to the procedure in step 3 and install the two VRMs 7 in the secondary microprocessor VRM connectors 8 . 5. Set the microprocessor core-ratio-selection switch (SW1) for the correct microprocessor core ratio. For example, if you have a 450 MHz microprocessor installed, be sure that the microprocessor core-ratio-selection switch is set to a microprocessor 352 Netfinity Server HMM
