Chapter 3. IBM NeXtScale n1200 Enclosure 45
3.6 Midplane
The enclosure midplane is the bridge to connect the compute nodes with the
power supplies, fan modules, and the FPC. Figure 3-10 shows the front and rear
of the midplane.

The midplane is used to provide power to all elements in the chassis. It also
provides signals to control fan speed, power consumption, and node throttling.
The midplane was designed with no active components to improve reliability and
minimize serviceability. Unlike BladeCenter, for example, the midplane is
removed by removing a cover on the top of the chassis.
