CFG mirror images in the stack after adding unit 4
Removing an NBU When you remove an NBU from a stack, the related
CFG mirror image in the stack becomes INACTIVE.
The AUR feature ensures that the stack always has two copies of an
INACTIVE CFG mirror image. These two copies must not reside in the
same unit in the stack.
For example, after you remove unit 4 from the stack shown in

becomes INACTIVE (see
125)). Another copy of the INACTIVE CFG 4 mirror image is also created
in unit 2.
