Removing a BU
When you remove a BU, 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 images of
the NBUs in the stack.
After you remove the BU from the stack shown in

stack (see
page 24). The feature also ensures that the stack always has two copies of an INACTIVE
CFG mirror image.
