Installing System Components 141
11 Lift the processor out of the socket and leave the release lever up so that
the socket is ready for the new processor.
After removing the processor, place it in an antistatic container for reuse,
return, or temporary storage.
NOTE: Do not touch the bottom of the processor. Touch only the side edges of
the processor.
If you are permanently removing the processor, you must install a processor
blank and a heat-sink blank in the CPU2 socket to ensure proper system
cooling. Adding the blanks is similar to installing a processor. See
"Installing a Processor" on page 141.
Installing a Processor
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.
NOTE: CPU1 socket must be used.
1 Remove the heat-sink blank and the processor blank from the vacant
processor socket. Removing the blanks is similar to removing a processor.
See "Removing a Processor" on page 138.
2 Remove the processor from the packing material by the processor’s edges
only. Do not touch the bottom of the processor. Handle the processor
carefully with your fingers on the side edges. Place your hand beneath the
processor when you are moving it to the system.
3 Locate the pin 1 indicator on the system board socket.
4 Locate the pin 1 indicator on the top of the processor. The pin 1 indicator
is shown as a triangle on the top of the processor. See Figure 3-27.
CAUTION: Positioning the processor incorrectly can permanently damage the
system board or the processor. Be careful not to bend the pins in the socket.
5 Place the processor over the socket with each pin 1 aligned and level.
SeeFigure3-27.
CAUTION: Do not use force to seat the processor. When the processor is
positioned correctly, it engages easily into the socket.
