IMPORTANT: You must run the supported version of the HP-UX operating system to utilize
the TPM security component.
WARNING! Ensure that the system is powered off and all power sources are disconnected
from the server prior to performing this procedure.
Voltages are present at various locations in the server whenever an ac power source is connected.
This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions can result in damage to the server.
Removing the TPM
To remove the TPM, follow these steps:
1. Back up the current TPM settings. See the HP-UX operating system documentation for more
information.
2. Power off the server and disconnect the power cables. See “Powering On and Powering Off
the Server” (page 78).
3. If rack mounted, slide the server completely out from the rack. See “Extending the Server
from the Rack” (page 142).
4. Remove the top cover. See “Removing the Top Cover” (page 143).
5. Grasp the TPM by the edges and lift it out of the socket on the system board. Figure 6-37
shows the location of the TPM on the system board.
CAUTION: If the TPM has failed, destroy the TPM after removing it from the server. Follow
local regulations to securely destroy the TPM.
If you use this procedure as part of a system board swap, transfer the TPM from the failed system
board to the new system board
