ReadyNAS 3138 Loses Network Connectivity
I have a rack mounted ReadyNAS 3138 with LAN ports 1 and 2 connected to a UniFi switch via LAG. Today, the NAS lost network connectivity. I tried power cycling, changing the ports, and changing cables, all with no effect. I then disconnected the existing connections and connected LAN port 4 to the switch trying to get a new DHCP lease for that NIC, but it does not establish a connection. I then tried doing a OS reinstall on the NAS, still with no resolution. Interestingly, when I power cycle the NAS, for a few seconds I do get a network link between the NAS and the switch, but it drops before the NAS has completed startup and become operational.
Any ideas from the community as to what could be going on, and with no network access to the NAS, how I can even troubleshoot?

FYI, that will remove the LAG from the config (and reset the password back to password). It also removes volume quota from the config.
I think the next step is to figure out if the issue is related to DHCP.
RAIDar should be able to find the NAS even if the IP address has failed over to something not on the subnet. So I'd try that.
You can also power down, and remove the disks (labeling by slot). Then power up diskless, and see if you get a persistent network connection.
Other steps would be to reboot the router and the switch.
Have you installed anything that would need to change/add network configuration files? If you have, and a file associate with it has become corrupt, that could cause the Ethernet mounting to fail to complete. Those files would not be touched by an OS re-install. See also if you get a connection in Support mode (see How-do-I-access-the-boot-menu-on-my-ReadyNAS-2304-3130-or-3138-storage-system ). If you get a connection, then try to telnet in as user root and password infr8ntdebug. If that works, it's your gateway for debugging, but exactly where to look for the problem I don't know.

Yep, that was the goal. Didn't help though, unfortunately.
Switch and router have been reset, and a diskless power up tried, all with no effect. And unfortunately RAIDar will not run on the only computer that I have available (M1 MacBook Pro running macOS 14.4).
