TPM 2.0 Considerations

Trusted platform module (TPM) version 2.0 is supported on Intel v3- or Intel v4-based platforms.

If there is an existing TPM 1.2 installed in the server, you cannot upgrade to TPM 2.0.

If there is no existing TPM in the server, you can install TPM 2.0. You must first upgrade to Intel v4

code, regardless of whether the installed CPU is Intel v3 or v4. TPM 2.0 requires Intel v4 code or later.

If your Intel v3 or Intel v4 system is currently supported and protected by TPM version 2.0, a potential

Caution

security exposure might occur if you downgrade the system software and BIOS to a version earlier than

those shown in Table 3 below.

If the TPM 2.0 becomes unresponsive, reboot the server.
