Installing a Trusted Platform Module (TPM)
The trusted platform module (TPM) is a small circuit board that plugs into a motherboard socket and is then
permanently secured with a one-way screw. The socket location is on the motherboard below PCIe riser 2.
TPM Considerations
•
This server supports either TPM version 1.2 or TPM version 2.0.
•
Field replacement of a TPM is not supported; you can install a TPM after-factory only if the server does
not already have a TPM installed.
•
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.
•
If the TPM 2.0 becomes unresponsive, reboot the server.
Installing and Enabling a TPM
Field replacement of a TPM is not supported; you can install a TPM after-factory only if the server does
not already have a TPM installed.
Note
This topic contains the following procedures, which must be followed in this order when installing and enabling
a TPM:
1
Installing the TPM Hardware
2
Enabling the TPM in the BIOS
3
Enabling the Intel TXT Feature in the BIOS
Installing TPM Hardware
For security purposes, the TPM is installed with a one-way screw. It cannot be removed with a standard
screwdriver.
Note
Step 1
Prepare the server for component installation:
a) Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server,
on page 39.
b) Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach
cables from the rear panel to provide clearance.
If you cannot safely view and access the component, remove the server from the
rack.
