Chapter 3 Maintaining the Server
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, underneath the cage for power supply 1.
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
Shutting Down and Powering Off the Server, page 3-8
.
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
Removing and Replacing the Server Top Cover, page 3-9
.
d.
Remove the PCIe riser 1, which contains PCIe slot 1 (see
Figure 3-23 on page 3-43
). See
Replacing
a PCIe Riser Assembly, page 3-35
for details.
e.
Remove power supply 1 from its cage. See
Replacing Power Supplies, page 3-58
for details.
Step 2
Install a TPM (see
Figure 3-29
):
a.
Locate the TPM socket on the motherboard, as shown in
Figure 3-29
.
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 that is 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.
Replace power supply 1 to the empty bay.
f.
Replace the PCIe riser 1.
g.
Replace the top cover.
h.
Replace the server in the rack, replace cables, and then power on the server by pressing the
Power
button.
Step 3
Enable the TPM:
a.
Watch during bootup for the F2 prompt, and then press
F2
to enter BIOS setup.
b.
Log into the BIOS Setup utility with your BIOS Administrator password.
c.
On the BIOS Setup utility screen, select the
Advanced
tab.
d.
Select
Trusted Computing
to open the TPM Security Device Configuration screen.
e.
Change TPM SUPPORT to
Enabled
.
f.
Press
F10
to save your settings and reboot the server.
