Installing a graphics processing unit in the 8001-12C system

Follow these steps to install a graphics processing unit in the IBM® Power® System S821LC (8001-12C) system.

1. Attach the electrostatic discharge (ESD) wrist strap.
   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.
2. The GPU can share the PCIe riser card with other PCIe adapters. Label and remove any cables and plugs that extend out of the adapters.
3. Remove the PCIe riser as shown in Figure 1.
   1. Retract the retaining pins (A) so that the arrows on the tabs point to the system.
   2. Lift the PCIe riser from the system.

4. Place the PCIe adapter riser on an ESD surface, with the riser up.
5. Plug the GPU (A) into the PCIe adapter riser (B) as shown in Figure 2. Secure the GPU tailstock with one or two screws as needed.

6. Place the PCIe adapter riser and the cards it contains into the system backplane as shown in Figure 3.
   1. Ensure that the PCIe holder release pins (B) are retracted, so the arrows point into the system.
   2. Use the alignment pins (A) and slots to help you properly insert the riser cards and replace the cover
   3. Reset the retaining pins to secure the PCIe cage.

7. Using your labels, replace any cables and plugs that you removed from the adapters.
8. Plug the GPU power cable into the system backplane as shown in Figure 4. Ensure that the cable latch clip snaps into place on the connector.
