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 a signicant number of
subsystems such as the processor, expansion cards, and other components.
Removing the system board
Prerequisites
CAUTION: Many repairs may only be done by a certied 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.
NOTE: This is a Field Replaceable Unit (FRU). Removal and installation procedures must be performed only by Dell
certied service technicians.
CAUTION: If you are using the Trusted Program 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. After the TPM plug-in module is
installed, it is cryptographically bound to that specic 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 Safety instructions section.
