Did you ever figure this out?

can you please tell me what device they are coming from? The async port is a console port. Once you find the NAS ip address,please get it physically checked what is connected on Console port, even if we have a console cable connected remove it. It seems like there is something that is causing a noise on console port (tty0).
On the NAS device, please use "show line" and check if there is noise appearing on the console port.
