Note -
Do not attempt to install a PCIe cable in the wrong direction. If excessive force is used
to install a PCIe cable, it may be damaged.
Note -
Ensure that the PCIe cables are firmly connected and secure.

When expanding the CPU memory unit upper or when replacing a PCIe cable,
connect the PCIe cable. You can reduce a CPU memory unit upper by performing the
procedure from step 2.
1.
Connect the three PCIe cables by matching their position labels of the PCle
cable with the corresponding position marks on the PCIBP board (A in the
figure).
The direction in which the PCIe cables are installed varies depending on the type
of the CPU memory unit.
When reducing a CPU memory unit upper, you do not have to perform this step
because the PCIe cables are not present.
