Installing a graphics processing unit in the 8335-GTB system

Learn how to install a graphics processing unit (GPU) in the IBM® Power® System S822LC (8335-GTB) system.

Before you begin

Power off the system and place it in the service position. For instructions, see Preparing the 8335-GTB system to remove and replace internal parts.

About this task

Attention: For safety and airflow purposes, if you remove parts from the system, you must ensure that:
  • PCIe tailstock fillers are present
  • Graphic processor unit (GPU) airflow tunnels are present.

Procedure

  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. Remove the two GPU airflow tunnels that cover the GPUs.
  3. Remove the GPU from the protective packaging. Remove the protective covers from the bottom of the GPU. Remove the cover starting with the corner of the cover.
  4. Remove the GPU socket protective covers from the system backplane and from the GPU.
  5. Carefully align the GPU and heat sink such that the alignment pins fit into the system backplane. Ensure that the arrow on the heatsink that indicates airflow points to the rear of the chassis. Insert the GPU into the system backplane. See Figure 1.

  6. Secure the GPU to the system backplane. Use a #2 Phillips head screw driver. Tighten the screws in the sequence shown in Figure 1. Start with the inner four screws. Thread the inner four screws half-way using the sequence shown. Once all four screws are threaded, then fully tighten them. Next tighten the outer four screws using the sequence shown.
  7. Repeat steps 3 through 6 for the second GPU.
  8. Replace the two GPU airflow tunnels that cover the GPUs. Use the alignment pins to properly insert the tunnels into the chassis.

What to do next

Prepare the system for operation. For instructions, see Preparing the 8335-GTB system for operation after you remove and replace internal parts.
