Installing or removing the ThinkServer Trusted Platform Module
This topic provides instructions on how to install or remove the ThinkServer Trusted Platform Module (TPM).
The TPM is a security chip designed by the Trusted Computing Group (TCG) to provide a hardware method
of data encryption. It stores passwords, encryption keys, and digital certicates to help provide security
solutions and protect the computer. You can purchase a TPM option from Lenovo.
Installing the TPM
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 69.
This topic provides instructions on how to install the TPM.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• Use any documentation that comes with the TPM and follow those instructions in addition to the
instructions in this topic.
• Depending on the model, your server might look slightly different from the illustration in this topic.
To install the TPM, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a at,
clean, and static-protective surface. See the Rack Installation Instructions that comes with the server.
3. Remove the server cover. See “Removing the server cover” on page 71.
4. Locate the TPM connector on the system board. See “System board components” on page 41. If
there is any PCI Express card installed on the riser card assembly 1, it might block your access to the
TPM connector on the system board. In this case, you need to remove the cooling shroud and then
carefully lift the riser card assembly 1 up so that you can access the TPM connector. You do not need to
disconnect any cables from the riser card assembly 1 or completely remove the riser card assembly 1.
5. Touch the static-protective package that contains the TPM to any unpainted surface on the outside of
the server. Then, take the TPM out of the package.
Note: Carefully handle the TPM by its edges.
