The RET port inside the AU can scan any RCU serial number carrying no link. The RET
port on the bottom of the AU only can scan the RCU serial number carrying no link
corresponding to passive AU arrays.
There is no priority on logical RCUs when links are established on them. Only one AISG
link can be established for an RCU serial number. If a link needs to be switched, you must
delete the configuration on the link so that the link can be released.
Once the RCU link is established, the RCU serial number is not displayed in the scanning
result of other RET ports.
