NOTE:
This is a Field Replaceable Unit (FRU). Removal and installation procedures should be performed only by Dell certified
service technicians.
CAUTION:
If you are using 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 motherboard. Once the TPM plug-in module is installed,
it is cryptographically bound to that specific motherboard. Any attempt to remove an installed TPM plug-in module breaks the
cryptographic binding, and it cannot be re-installed or installed on another motherboard.
