The CPU is installed in a socket on the motherboard. Before you remove the CPU from its
socket, remove the motherboard from the chassis (see

If you remove the CPU from the motherboard in order to install it on a new motherboard,
unpack the new motherboard and remove the protective plastic cover on the CPU socket.
Transfer the protective cover to the CPU socket of the old motherboard to protect the
circuitry. Follow standard ESD precautions while handling the motherboard and all
components.

1 Shut down, and then open the Fiery Server (see pages
34
and

).
To access the CPU, you must remove the left panel.
2 Remove the CPU fan cable from motherboard connector FAN 1.
3 Remove the CPU cooling assembly.
• Insert a flathead screwdriver into the groove on the top of a fastener cap and rotate the
fastener counterclockwise (that is, in the direction of the arrow) to the position shown
below.

• Pull straight up on the fastener cap until the peg is out of the motherboard.
You may need to use moderate force to pull the pegs out of the motherboard. Be careful
not to damage the components on the motherboard or the CPU cooling assembly when
pulling up on the fasteners.

1 Unlock the CPU socket lever and raise it into the open position (flex the lever away from the
retention post, and then raise it).

4 Wipe the contact surface of the CPU (the smooth, gray side of the chip) with a clean, lint-
free cloth to ensure proper contact with the new heatsink.
If you remove the CPU from the motherboard to install it on a new motherboard, make sure
that you completely remove any thermal compound residue on the surface of the CPU and at
the base of the heatsink. It may help to scrape all the residue off of the surface using the flat
edge of something non-conductive.

5 Prepare the CPU socket by ensuring that:
• The socket lever is in the open position.
• The load plate is open.
6 Place the CPU in the socket.
The CPU and the socket are keyed to ensure correct installation. The notches on the edges of
the CPU correspond with the two small posts inside the socket. Align the yellow triangle on
the CPU with the yellow triangle on the socket. Do not force the CPU.

Before you install the cooling assembly, completely remove any thermal compound
residue on the surface of the CPU and the base of the heatsink, and then apply a fresh thermal
compound square to the base of the heatsink. When installing the thermal compound square,
make sure to remove the plastic backing on both sides of the square. Avoid creating any
bubbles or wrinkles on the square. Bubbles and wrinkles reduce the heat-transfer efficiency of
the cooling assembly.

the cooling assembly.
1 Prepare the CPU cooling assembly for installation.
• Make sure that the motherboard is placed on a padded, static-free work surface.
• Apply a fresh thermal compound square, as described in the note above.
• Align the cooling assembly so that when it is installed, the fan cable easily reaches the CPU
fan power connector FAN 1 on the motherboard.
2 Place the heatsink over the CPU socket.
3 At alternate corners, press down on each fastener to engage the mount on the motherboard.
Engage all four pegs.

Do not rotate the fasteners after installation.
Engaging the pegs at alternate corners applies clamping force equally over the CPU and
socket. Avoid using excessive force and take care not to flex the motherboard when you engage
the pegs.

the pegs.
4 Connect the CPU fan cable to the motherboard connector FAN 1.
If you are installing a new CPU, secure slack in the fan cable using a tie-wrap. The tie-wrap
prevents the fan cable from interfering with the CPU fan. Also, make sure the connector on
the cable is securely connected to the motherboard.
