What to do next
Prepare the system for operation. For instructions, see “Preparing the 8001-12C or 8005-12N system for
operation after you remove and replace internal parts” on page 72.

Removing a PCIe adapter from the 8001-12C or 8005-12N system
Learn how to remove a PCIe adapter from the IBM Power System S821LC (8001-12C) or the IBM CS821
(8005-12N) system.
Before you begin
Power off the system and place it in the service position. For instructions, see “Preparing the 8001-12C or
8005-12N system to remove and replace internal parts” on page 70.
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. An adapter can share a PCIe riser card with other adapters. Label and remove any cables and plugs
that extend out of the adapters. See Figure 32.

3. If you are working with a PCIe adapter in positions 2, if the adapter has a special tailstock support,
unscrew the tailstock from the support. Remove the adapter from the PCIe riser.
4. If you are working with the PCIe riser card in position 1, do the following steps:
a. If a PCIe adapter is in position 2, label and remove that adapter. Set it on an ESD mat for future
replacement.
