Note -
When mounting a CPU memory unit board, check the connectors on both of
the CPU memory unit board and frame beforehand to confirm that no pin is bent and
all the pins are neatly arranged in lines. If there is a bent pin in a connector, mounting
a CPU memory unit board may damage the CPU memory unit or frame. Also,
carefully proceed with the work to prevent any pin from being bent.
Note - A part of the procedure varies depending on the CPU memory unit type. To
determine the CPU memory unit type, check the label in Figure 7-2 .
Note - Be careful when removing the filler unit so that it does not catch on any PCIe cable.
Note - Use PCIe cables without removing the packaging material covering the connector part
of the cable.
Note - The shortest PCIe cable is no longer necessary during maintenance. Connect it to the
removed CPU memory unit, and return them together.
7.7.1 Installing the CPU memory unit upper
Install the CPU memory unit upper on the CPU memory unit lower. When replacing
the CPU memory unit lower, install the CPU memory unit upper on the new CPU
memory unit lower.
For expansion of a CPU memory unit upper, perform the same procedure. When
removing the CPU memory unit upper, install a filler unit in its place.
1.
When installing a filler unit for the CPU memory unit lower connected with
PCIe cables, move the PCIe cables (A and B in the figure) further apart toward
the outside of the chassis.
