Table 2. Memory configuration as a function of the number of DIMMs and risers. You read this table by selecting the
individual DIMM size row in the leftmost column, then move to the right and select the columns for the memory
capacity. The riser quantity value that is listed is the quantity of the memory feature code that can be ordered, which
corresponds to the DIMM size in the leftmost column.

Removing and replacing PCIe adapters in the 8335-GTB
Learn about removing and replacing Peripheral Component Interconnect (PCI) Express (PCIe) adapters in
the IBM Power System S822LC (8335-GTB) system.
Attention:
For safety and airflow purposes, if you remove parts from the system, you must ensure that:
v
PCIe tailstock fillers are present
v Graphic processor unit (GPU) airflow tunnels are present.
Removing a PCIe adapter from the system backplane in the 8335-GTB
Learn about removing Peripheral Component Interconnect (PCI) Express (PCIe) adapters 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” on page 195.
About this task
Attention: For safety and airflow purposes, if you remove parts from the system, you must ensure that:
v PCIe tailstock fillers are present
v Graphic processor unit (GPU) airflow tunnels are present.
Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
Attention:
v 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.
v
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.
v 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. If needed, label and remove the cables from the PCIe adapter. Also, if needed, label and remove any
plugs that extend out of the PCIe adapter.
