HP Integrity rx2660 Server User Service Guide

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.
These voltages are 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:
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 77).
3. If rack mounted, slide the server completely out from the rack. See “Extending the Server from
the Rack” (page 141).
4. Remove the top cover. See “Removing the Top Cover” (page 142).
5. Grasp the TPM by the edges and lift it out of the socket on the system board. Figure 78 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
