6 Processor Installation
Installing a Processor
  WARNING: Only trained service technicians are authorized to remove the system 
cover and access any of the components inside the system. Before you begin this 
procedure, review the safety instructions that came with the system.
 
NOTE: In a single-processor configuration, the CPU1 socket must be used.
1
If you are adding a second processor for the first time, remove the heat-
sink blank and the processor blank from the vacant processor socket. 
Removing the blank is similar to removing a processor. See "Removing a 
Processor".
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 1-4.
  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. 
See Figure 1-3 and Figure 1-4.
  CAUTION: Do not use force to seat the processor. When the processor is 
positioned correctly, it engages easily into the socket.
6 Align the notches in the 
p
rocessor with the 
socket keys on t
he ZIF 
socket. See 
Figure 1-4.

I
nstall the processor in the socket. Keep the processor level 
(see Figure 1-3) and insert it straight down into the socket. 
Allow the 
processor to float on the pins, allowing the processor shield to hold it 
in place.
