SG135 + AP55 - License expired - How to reset AP55?

Hello Denis,

what do you want to achieve? You do not need to "reset" the APs to build a lab with them.

In the past I could not bind an AP55 already controlled by another UTM to a new UTM. So I thought I had to reset the AP55 first. Isn't this necessary?

Depends on the AP configuration. Normally it tries IP 1.2.3.4 Port 2712 if it cannot connect to the (previous) controller as described in the provisioning documentation.

However if everything was configured statically this might not happen. In this case the Sophos flash tool (grab the firmware file from the UTM filesystem) might be necessary - it reflashes the AP removing all previous configuration.

Thanks for the information.

jprush was kind enough to help me out with a test license.

For whatever reason, the three AP55 were not recognized by my test UTM (VM). They just didn't show up under "Pending APs".

This morning, after activating the expired license on the SG135 (which previously managed these three APs). I was then able to delete them there and They just reappeared on this SG135 under "Pending APs" a short time later.

Only then they were also recognized by my test UTM and I haven't been able to figure out why that was yet.

I had previously tried unsuccessfully to re-flash the three AP55 with the Sophos Flashutility, but the Flashutility didn't recognize them - presumably because they still had running firmware and were able to boot successfully?

Finally, I was able to put the devices into operation in my desired test environment. Many thanks especially to jprush and also to Alan Brand for the help and tips.

Hallo Denis and welcome to the UTM Community!

The approach in ASG 425 Display with home license might also be helpful.
