What does a slow amber-flashing Stack-LED indicate?

A slow, amber-flashing Stack-LED on an ArubaOS-CX switch indicates that the Virtual Switching Framework (VSF), or stacking, has been enabled on the device. However, the switch has not yet successfully formed or joined a stack. This state signifies that the switch is configured for stacking and is in a "ready" or "waiting" state, pending the connection of VSF links and the completion of the stacking process with other compatible switches.

A. A solid amber LED, not a slow-flashing one, typically indicates a VSF hardware failure on the switch.
B. A fast-flashing amber LED indicates a VSF port link is down or there is a VSF misconfiguration. If stacking mode were not selected, the LED would be off.
D. This state is not explicitly defined for a slow amber flash. The slow amber flash indicates the prerequisite state before synchronization and joining a stack can occur.

but the switch is not yet a member of a stack."
