IBM Power System 9008-22L Manual page 16

Procedure
1. Ensure that the required software is installed to support the new feature. See the Power Systems
Prerequisites website.
Important: If you are installing a PCIe3 cable adapter and want to connect a PCIe3 expansion
drawer via the HMC, you must have the HMC driver 9.1.921.0 or later installed.
2. Take appropriate precautions for avoiding electric shock and for handling static-sensitive devices. For
more information, see "Avoiding electric shock" on page 62 and "Handling static-sensitive devices"
on page 64.
3. If you are installing a PCIe3 cable adapter, ensure that the target slot is Unassigned in the I/O
properties field for the managed server you are working on.
4. If applicable, open the rack door at the rear of the system.
5. Review the locations of the PCIe adapter slots and the light-emitting diodes (LEDs) for the PCIe
adapters. The PCIe adapters are viewed at the rear of the system.
The number of the PCIe adapter slots that are available in the system depends on the number of
system processors in the system. For the PCIe adapter placement information in this system, see
PCIe adapter placement rules and slot priorities for the 9008-22L, 9009-22A, or 9223-22H.
The PCIe adapter has two LEDs that indicate the status:
• A power/activity LED (green)
• An error and identify function LED (amber)
