Removing a Processor Blank
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.
1
Before upgrading your system, download the latest system BIOS version
from
support.dell.com
compressed download file to install the update on your system.
NOTE: You can update the system BIOS using the Dell Lifecycle Controller.
2
Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet. When disconnected from AC power,
press and hold the power button for 10 seconds to fully drain the system of
stored power prior to removing the cover.
NOTE: It is recommended that you always use a static mat and static strap
while working on components in the interior of the system.
3
Open the system. See "Opening the System" in the Owner’s Manual.
4
Remove the cooling shroud. See "Removing the Cooling Shroud" in the
Owner’s Manual.
CAUTION: The processor blank is held in its socket under strong pressure.
Be aware that the release lever can spring up suddenly if not firmly grasped.
5
Position your thumb firmly over the processor-blank socket-release lever
and release the lever from the locked position by pushing down and out
from under the tab. Rotate the lever upward.
6
Rotate the processor shield upward and out of the way.
7
Lift the processor blank out of the socket and leave the release lever up so
that the socket is ready for the new processor. See Figure 1-1.

Installing the Second Processor
CAUTION: 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.
1
Ensure that you have followed the steps mentioned in "Before You Begin"
on page 3.
2
Unpack the new processor.
CAUTION: Positioning the processor incorrectly can permanently damage the
system board or the processor. Be careful not to bend the pins in the socket.
CAUTION: Do not use force to seat the processor. When the processor is
positioned correctly, it engages easily into the socket.
3
Align the notches in the processor with the socket keys on the ZIF socket
and set the processor lightly in the ZIF socket. See Figure 1-1.
4
Close the processor shield.
5
Using a clean lint-free cloth, remove the thermal grease from the heat sink.
CAUTION: Applying too much thermal grease can result in excess grease coming
in contact with and contaminating the processor socket.
6
Open the grease applicator included with your processor kit and apply all
of the thermal grease in the applicator to the center of the topside of the
new processor.
7
Place the heat sink on the processor.
8
Tighten the heat-sink retention sockets. See Figure 1-2.
