Blast it with a heat gun or your girlfriend’s blow dryer for a moment to release the glue. Not the lesson that they should never put a USB stick in a device! Old and Busted. I guess they learned some lessons from the EdgeRouter Lite USB failure debacle. With a quick search of the Googles I found fresh knowledge that it is, in fact, a generic USB stick, and that replacing it is as simple as putting in a blank drive and holding the Reset button on boot. My discovery of this was accidental - I was mucking around on my new UNVR and decided to run lsbusb -tv and there it was. What I hadn’t learned, yet, was that the internal storage is a USB stick. On a Sunday.Īt the time I’d seen hints that wearing out the internal storage was not uncommon. I pulled the drives, tried the Reset button, and thanked the Deities that I live in an area where a UNVR is something that I can buy. Once adopted, set the Static IP for the new IP range as desired.Early last month, my 20-month old UNVR stopped working. In that state, the switch should be able to connect and re-adopt at the new location. Next time, before disconnecting the switch at the old office, set it back to dynamic IP (“Using DHCP”), then choose Move this device to… the new office. After that, I went back in and reset the switch’s name and Static IP. Once the device had been removed from the controller, because its IP and set-inform were already correct, it immediately re-appeared in the controller as “Pending Adoption.” I just clicked the Adopt button in the controller and very soon saw the switch Connected in the new office. If you try to forget while the status is Adopting, it says that the device is busy. The only trick was hitting the Forget button in the one-second gap between adoption attempts, when the status showed Disconnected. The solution was fairly simple: I needed to fully forget the device in the controller. However, issuing a factory reset generated a new fingerprint the MAC for the device was known by the controller but the fingerprint was not, so it rejected the adoption. ![]() That could have been adopted if the device’s IP address had allowed talking to the new network. On the controller, I see hundreds of errors like this in C:\Users\\Ubiquiti UniFi\logs\server.log: ERROR inform - invalid fingerprint: expecting, payload=], discovery_response=false, dualboot=true, ever_crash=false, fingerprint=e6:87:89:c1:0f:8f:c6:54:b5:d1:a5:7b:6f:f1:f4:b3:74:c0:b1:4f, Īlthough not explained, the “invalid fingerprint” makes sense: before the factory reset, the device had a fingerprint corresponding to a configuration in the controller. Now, info shows that the server is rejecting the adoption: Using the new dynamic IP, I was able to SSH into the switch with the default username and password (ubnt / ubnt). After this, the switch appeared in the dashboard with a dynamic IP in the new office’s IP range and immediately launched into an endless Adopting… loop. Note that this loses all custom configuration, ports names, etc. I couldn’t find simple instructions to change the static IP of the switch, so I just did a restore-default to reset it to factory defaults. When I ran info, it showed the correct set-inform status but I think it said “Unreachable”, which makes sense, since its IP was still on a different network.Ĥ. I connected a laptop directly to the switch, set the NIC on the laptop to a fixed IP in the old office’s range, and connected to the switch via SSH. but in the dashboard, it still showed the old static IP and could not be managed. ![]() The switch started passing traffic on the new network. On site, connect the switch to the network in the new office. Under Config > Network, update the Static IP to use an IP Address and Gateway in the IP range in the new office.ģ. Under Config (gear icon) > Manage Device > Forget this device, do not click Forget but rather choose Move this device to… the new office.Ģ. It was already offline by the time I started this process.ġ. Here are the steps that led to that issue and the solution. I needed to move a switch to the new, consolidated site but wound up with a “Server Reject” adoption loop. Each office had its own USG and its own range of IP addresses. ![]() A customer was consolidating two offices into one.
