CAUTION: Positioning the processor incorrectly can permanently damage the system board or the processor. Be careful not to bend the pins in the socket. a) With the release lever on the processor socket in the open position, align the processor with the socket keys and set the processor lightly in the socket. CAUTION: Do not use force to seat the processor. When the processor is positioned correctly, it engages easily into the socket. b) Close the processor shield. c) Rotate the socket release lever down until it snaps into place. 5. Install the heat sink: CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket. a) If applicable, open the grease applicator included with your processor kit and apply all of the thermal grease in the applicator to the center of the topside of the new processor. b) Place the heat sink onto the processor. c) Tighten the four screws to secure the heat sink to the system board. NOTE: Do not over-tighten the heat sink retention screws when installing the heat sink. To prevent over-tightening, tighten the retention screw until resistance is felt, and stop once the screw is seated. The screw tension should be no more than 6 in-lb (6.9 kg-cm). 6. Install the cooling shroud. 7. Close the system. 8. If applicable, place the system upright on a flat, stable surface and rotate the system feet outward. 9. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals. 10. Press to enter the System Setup and check that the processor information matches the new system configuration. 11. Run the system diagnostics to verify that the new processor operates correctly. Redundant AC Power Supply Your system supports up to two 495 W or 750 W redundant AC power supplies. When two identical power supplies are installed, the power supply configuration is redundant (1 + 1). In redundant mode, power is supplied to the system equally from both power supplies to maximize efficiency. When only one power supply is installed, the power supply configuration is non-redundant (1 + 0). Power is supplied to the system only by the single power supply. NOTE: If two power supplies are used, they must be of the same type and have the same maximum output power. NOTE: Redundant power supplies are supported on systems with hot-swappable hard drives only. NOTE: When selecting or upgrading your system configuration, verify the system power consumption with the Dell Energy Smart Solution Advisor at dell.com/ESSA to ensure optimum power utilization. Removing A Redundant AC Power Supply CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product. 96
