Lightly press down on the top of the processor while closing the socket lever. 4 Check for proper processor seating in the socket by carefully trying to lift the processor out of the socket with your fingers. A properly seated processor does not lift out of the socket. System Board To remove the system board: 1 Disconnect power from the system (page 66), remove the access panel (page 71), lay the workstation on its side with the system board facing up, remove all expansion boards and graphics cards (page 84), and remove the CPU heatsink (page 96). 2 Disconnect all cabling from the system board. CAUTION Be sure you can differentiate which power cable was disconnected from the PCI Express x16 graphics card and which power cable was disconnected from the system board. These two cables look very similar. The PCI Express power cable has a black connector and the power cable has a white connector. When power is present, you must NEVER connect the PCI Express power cable to the system board. If you do so, the system board may be damaged and your warranty voided. To see a picture of the PCI Express cable and where it must be connected, refer to the "PCI or PCI Express Installation" section on page 84. NOTE Make note of the cable connections before disconnecting them from the system board. Refer to "Power Connections to Drives" section on page 87 for more information. 3 Slide the system board forward 1 to disengage the plastic mounting standoffs from the chassis.
