Removing the system board
Installing the system board

A system board (also known as the motherboard) is the main printed circuit board found in systems. The system board allows communication between many of the crucial electronic components of the system, such as the central processing unit (CPU) and memory, and also provides connectors for other peripherals. Unlike a backplane, a system board contains significant number of sub-systems such as the processor expansion cards, and other components.

Removing the system board

* 
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 are shipped with your product.
* 
CAUTION: If you are using the Trusted Platform Module (TPM) with an encryption key, you may be prompted to create a recovery key during program or System Setup. Be sure to create and safely store this recovery key. If you replace this system board, you must supply the recovery key when you restart your system or program before you can access the encrypted data on your hard drives.
* 
CAUTION: Do not attempt to remove the TPM plug-in module from the system board. Once the TPM plug-in module is installed, it is cryptographically bound to that specific system board. Any attempt to remove an installed TPM plug-in module breaks the cryptographic binding, and it cannot be re-installed or installed on another system board.
1.
Follow the safety guidelines listed in the Safety instructions section.
2.
Follow the procedure listed in the Before working inside your system section.
3.
Remove the following:
a.
Cooling shroud
b.
Cooling fan assembly
c.
Power supply unit(s)
d.
All expansion card risers
e.
Integrated storage controller card
f.
Internal dual SD module
g.
Internal USB key (if installed)
h.
PCIe card holder
i.
Cable retention bracket
j.
Heat sink(s)/heat sink blank(s)
k.
Processors(s)/processor blank(s)
* 
CAUTION: To prevent damage to the processor pins when replacing a faulty system board, ensure that you cover the processor socket with the processor protective cap.
l.
Memory modules and memory module blanks
m.
Network daughter card
1.
Disconnect all cables from the system board.
* 
CAUTION: Take care not to damage the system identification button while removing the system board from the chassis.
* 
CAUTION: Do not lift the system board by holding a memory module, processor, or other components.
2.
Hold the system board holder, lift the blue release pin, lift the system board, and then slide it toward the front of the chassis.
Sliding the system board toward the front of the chassis disengages the connectors from the back of the chassis slots.
3.
Lift the system board out of the chassis.

a.
Cable retention bracket
b.
PCIe card holder
c.
Integrated storage controller card
d.
Internal USB key (if applicable)

NOTE: Ensure that the cables inside the system are routed along the chassis wall and secured using the cable securing bracket.
4.
Follow the procedure listed in the After working inside your system section.
5.
Import your new or existing iDRAC Enterprise license. For more information, see Integrated Dell Remote Access Controller User's Guide, at Dell.com/esmmanuals.
6.
Ensure that you:
a.
Use the Easy Restore feature to restore the Service Tag. For more information, see the Easy restore section.
b.
If the Service Tag is not backed up in the backup flash device, enter the system Service Tag manually. For more information, see the Entering the system Service Tag section.
c.
