CFG mirror images after removing unit 4

Removing a BU When a BU is removed, the TEMP-BU assumes the role of the BU. Because all the CFG mirror images of the NBUs reside in the removed BU, the TEMP-BU mirrors all the CFG image of the NBUs in the stack.

After the removal of the BU from the stack shown in Figure 16 "CFG mirror images in the stack after adding unit 4" (page 57), the TEMP-BU (unit 2) has to mirror all the CFG images in the stack (see Figure 18 "CFG mirror images in the stack after removing the BU (unit 1)" (page 59)). The feature also ensures that the stack always has two copies of an INACTIVE CFG mirror image.
