							Removing The iDRAC Ports Card
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.Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet and 
peripherals.
2.Open the system.
3.Disconnect any cables connected to the iDRAC Ports card.
4.Lift the expansion-card latch.
5.If installed, remove the expansion card from expansion-card riser 1.
6.Supporting the expansion-card riser by the touch points, hold the iDRAC Ports card by its edges and remove it from  the iDRAC Ports card connector on the riser.
7.If you are removing the card permanently, install a metal filler bracket over the empty expansion slot opening and close the expansion-card latch.
NOTE: You must install a filler bracket over an empty expansion slot to maintain Federal Communications 
Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the system and aid in 
proper cooling and airflow inside the system.
8.Close the system.
9.Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.

Processors
Use the following procedure when:
•Installing an additional processor
•Replacing a processor
NOTE: To ensure proper system cooling, you must install a processor blank and a heat-sink blank in any empty 
processor socket.
Removing 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.
1.Before upgrading your system, download the latest system BIOS version from dell.com/support and follow the 
instructions included in the compressed download file to install the update on your system.
NOTE: You can update the system BIOS using the 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 three seconds to fully drain the system of stored 
power prior to removing the cover.
3.Open the system.
4.Remove the cooling shroud.
WARNING: The heat sink and processor are hot to the touch for some time after the system has been 
powered down. Allow the heat sink and processor to cool before handling them.
77 
						

							CAUTION: Never remove the heat sink from a processor unless you intend to remove the processor. The heat 
sink is necessary to maintain proper thermal conditions.
5.Loosen the heat-sink retention sockets.
6.Lift the heat sink away from the processor and set the heat sink aside.

CAUTION: The processor is held in its socket under strong pressure. Be aware that the release lever can 
spring up suddenly if not firmly grasped.
7.Position your thumb firmly over the processor socket-release lever and release the lever from the locked position 
by pushing down and out from under the tab. Rotate the lever upward.
8.Rotate the processor shield upward and out of the way.
CAUTION: The socket pins are fragile and can be permanently damaged. Be careful not to bend the pins in the 
socket when removing the processor out of the socket.
9.Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new  processor.

NOTE: After removing the processor, place it in an antistatic container for reuse, return, or temporary storage. 
Do not touch the bottom of the processor. Touch only the side edges of the processor.
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: If you are installing a single processor, it must be installed in socket CPU1.
NOTE: If you install a second processor, you must remove the dummy fan from the FAN 6 slot, install a cooling fan 
in the FAN 6 slot, and upgrade both the riser cards (riser1 and riser 2). For more information, see Expansion Card 
Installation Guidelines.
NOTE: When installing a second processor in your system with a 350 W redundant power supply, it is highly 
recommended that you upgrade to 550 W redundant power supply, to avoid potential degraded performance.
1.Before upgrading your system, download the latest system BIOS version from dell.com/support and follow the 
instructions included in the compressed download file to install the update on your system.
79 
						

							NOTE: You can update the system BIOS using the Lifecycle Controller.
2.Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet. When 
disconnected from the power source, press and hold the power button for three seconds to fully drain the system  of stored power prior to removing the cover.
3.Open the system.
4.Remove the cooling shroud.
WARNING: The heat sink and processor are hot to the touch for some time after the system has been 
powered down. Allow the heat sink and processor to cool before handling them.
CAUTION: Never remove the heat sink from a processor unless you intend to remove the processor. The heat 
sink is necessary to maintain proper thermal conditions.
5.Remove the heat sink/heat-sink blank and processor/processor blank, as applicable.
NOTE: The procedure to remove the heat-sink blank or processor blank is similar to removing a heat-sink or 
processor.
6.Unpack the new processor.
7.Release the lever from the locked position by pushing down and out from under the tab.
8.Rotate the processor shield upward and out of the way.
9.Align the processor with the socket keys on the ZIF socket.
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.
10.With the release lever on the processor socket in the open position, align the pin of the processor, using the pin 
position guide on the socket, as reference and set the processor lightly in the socket.
11.Close the processor shield.
12.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.
13.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.
14.Place the heat sink on the processor.
15.Using a #2 Phillips screwdriver, tighten the heat-sink retention sockets.
16.Install the cooling shroud.
17.Close the system.
18.Reconnect your system and peripherals to their electrical outlets, and turn on the system.
19.Press  to enter the System Setup and check that the processor information matches the new system 
configuration.
