that is connected to the lower section of the midplane. All other components plug into one section only (upper or lower). However, there is another matching component that can plug into the other midplane section for redundancy.

It should be noted that the upper and lower midplane sections in an IBM Eserver BladeCenter are independent of each other (see Figure 2-3). Having a dual midplane ensures that there is no single point of failure and the blades remain operational.
