To install or replace a trusted platform module (TPM), follow these steps:
Step 1 Remove a TPM:
a. Power off the server as described in the “Shutting Down and Powering Off the Server” section on
page 3-7.
b. Disconnect all power cords from the power supplies.
c. 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.
d. Remove the top cover as described in the “Removing and Replacing the Server Top Cover” section
on page 3-9.
e. Remove the PCIe riser card assembly to provide clearance to the TPM.
See the “Replacing a PCIe Riser Card Assembly” section on page 3-33 for instructions.
f. Remove the securing screw that holds the TPM to the motherboard standoff (see Figure 3-20).
g. Lift up on both ends of the TPM to free it from the socket on the motherboard.
Step 2 Install a TPM:
a. Align the connector that is on the underside of the new TPM with motherboard socket JP2, and then
press firmly on both ends of the TPM to press the connector into the socket.
b. Replace the securing screw that holds the TPM to the motherboard standoff.
