Installing or Replacing Server Components
Installing a Trusted Platform Module 
The trusted platform module (TPM) is a small circuit board that attaches to a motherboard socket. The 
socket location is on the motherboard, below PCIe riser 2 (see 
Figure 3-23).
Note For security purposes, the TPM is installed with a one-way screw. It cannot be removed with a standard 
screwdriver.
To install a trusted platform module (TPM), follow these steps:
Step 1 Prepare the server for component installation.
a. Power off the server as described in the “Shutting Down and Powering Off the Server” section on 
page 3-6.
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. 
Caution If you cannot safely view and access the component, remove the server from the rack.
c. Remove the top cover as described in the “Removing and Replacing the Server Top Cover” section 
on page 3-7.
d. Remove PCIe riser 2 to provide access to the TPM socket that is on the motherboard (see 
Figure 3-23).
See Replacing a PCIe Riser, page 3-28 for more information.
Step 2 Install a TPM (see Figure 3-23):
a. Locate the TPM socket on the motherboard, as shown in Figure 3-23.
b. Align the connector that is on the bottom of the TPM circuit board with the motherboard TPM 
socket. Align the screw hole and standoff on the TPM board with the screw hole adjacent to the TPM 
socket.
c. Push down evenly on the TPM to seat it in the motherboard socket.
d. Install the single one-way screw that secures the TPM to the motherboard.
e. If you removed PCIe riser 2, replace it now. 
f. Replace the top cover.
g. Replace the server in the rack, replace cables, and then power on the server by pressing the Power 
button.
Note The TPM and the Intel Trusted Execution Technology (TXT) feature must be enabled in the 
server BIOS. If you have not previously enabled the TXT and TPM, continue with 
Enabling the 
Intel Trusted Execution Technology (TXT) Feature For the TPM, page 3-40.
