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 following figures that show the locations of the PCIe adapter and cassette slots and the
locations of the LEDs for the adapters. The PCIe adapter cassettes that contain the PCIe adapters are
installed in 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 for the available slots
in this system, see PCIe adapter placement rules and slot priorities for the 9080-M9S.
The PCIe adapter locations have six digits. The PCIe cassette locations have four digits.
Figure 1. Locations for the PCIe adapters and cassettes in the 9080-M9S system
The PCIe adapter has three LEDs that indicate the following status:
• A power/activity LED (green)
• An identify function LED (amber) for the PCIe adapter (labeled C1)
• An identify function LED (amber) for the cassette (labeled with an exclamation mark)
