Replacing parts
• Transfer options to the new motherboard using the motherboard replacement dongle (for details, see page 63).
To install the motherboard
1 If protective covers are present on the CPU sockets on the new motherboard, remove them. Then install the covers on
the CPU sockets on the old motherboard to protect the circuitry.
2 If you are installing a new motherboard, install the DIMMs and CPUs from the old motherboard onto the new
motherboard. For DIMMs, see page 66; for CPUs, see page 69.
• Make sure to use the fresh thermal compound that came with the new motherboard when transferring CPUs onto the
new motherboard (for details, see page 71).
• Make sure that the motherboard is placed on an antistatic surface with some padding.
• Do not transfer the BIOS chip from the old motherboard onto the new motherboard. Doing so can cause the system
to shut down due to incompatibility issues.
3 Align the mounting holes in the motherboard with the mounting posts on the chassis.
4 Install the CPU cooling assemblies that you removed earlier.
For detailed installation instructions, see page 69.
5 Insert the motherboard mounting screws that secure the motherboard to the chassis (see Figure 32 on page 58).
Important: Follow these guidelines:
Important: Always install the CPU cooling assemblies before installing the motherboard mounting screws. You
may flex and damage the motherboard if you perform the installations in the wrong order.
Important: Partially tighten each mounting screw before completely tightening any one screw. Do not over-
tighten the screws; doing so could damage traces on the motherboard.
