If you unplug NSA325v2's disk and plug it to new NAS device, it may not work due to different file system format. You can backup data in somewhere, and then copy it to new NAS device. Or using backup feature of NSA325v5 to backup data to new NAS device.

Do you mean when NAS542 is plugged its power adapter, LED no light? I think you can contact ZYXEL EU technical support (Submit Request or Phone Support). https://support.zyxel.eu/hc/en-us/requests/new
