This read-only BITS object reports the system status before a reset action is performed, with bit values for ok, no-stack-integrity, and downgrade, noting that reset is blocked in stackable products if not all stack units run the same image release. An admin checks this before rebooting a stack to see if there are blocking conditions, such as mismatched firmware versions across units or pending CDB file actions tied to a downgrade. For example, seeing the no-stack-integrity bit set warns the admin that stack units are running different firmware releases and a reset may be prevented or cause instability until versions are aligned.
