Removing and replacing the TPM card in the 9006-12P system

Learn how to remove and replace the trusted platform module (TPM) card in the IBM® Power® System LC921 (9006-12P) system.

1. Attach the electrostatic discharge (ESD) wrist strap.
   The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is completed, and if applicable, until the service access cover is replaced.

   Attention:

   • Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging your hardware.
   • When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is used for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds. If at any point in this service process you move away from the system, it is important to again discharge yourself by touching an unpainted metal surface for at least 5 seconds before you continue with the service process.
2. If needed, remove two or three memory modules near the TPM for clearance.
   For instructions, see Removing and replacing memory in the 9006-12P system.
3. Remove the TPM card (A) as shown in Figure 1.

   

4. Replace the TPM card as shown in Figure 2.
   The TPM card must be plugged in properly. Check the pins on the card and the holes in the card socket to properly orient the TMP card. One of the TPM card socket holes is filled in; the corresponding pin on the TPM connector that is removed.

   

5. Replace any memory modules that you removed.
