POE switch stuckin 'adopting' or 'disconnected'
I recently installed a new Omada network.
- OC200 controller
- TL-R605 router
- TL-SG3428 switch
- TL-SG2210 POE switch
- 2 x EAP610 access points
Router connects to the 24-port switch, which connects to the 8-port POE switch, which powers the EAPs and the OC200.
Initially the setup of this went well. Then the TL-SG2210MP POE switch started to randomly disconnect from the Omada controller, but the attached devices remained powered and connected. Powering off/on the switch, or even the entire network did not help. The POE switch started to drop out more frequently, and finally never connected anymore.
So after some time I pressed the 'reset' button on the front panel. The switch appeared again in the Omada controller as 'Pending'. I then pressed the 'Adopt' button. At that point, the switch got adopted, configured and connected, but 5 minutes later it switched back to 'adopting' and it had been at this status now for quite some time. It also now has an IP address which is not in de DHCP range of one of the VLANs (it should get a fixed address in the 100 range, just like the other devices.)
Running Omada controller firmware 5.0.30.
Any suggestions how to fix this? Is this a problem of the switch, the router or the controller?
