AP541N returns to default config

Hello,

one of my ap541n access points behaves strangly.

It returns out of the blue to the default config.

This is what the log tells me:

Oct 3 05:36:10 err mDNSResponder mDNSPlatformRawTime went backwards by 2138801570 ticks;  setting correction factor to 862212335

Any idea what can cause this issue?

I have to add that once rebooted into default config, the webinterface responds really slow.

argh, whatever I do... it keeps rebooting into default config.

I guess this is a harware issue.

Hardware issue is ruled out. I replaced the access point with another one.

Same behaviour.

I get the idea that the problem starts when joining the cluster.

For anyone who experiences the same problem => CHECK THE MAX PoE OUTPUT OF PoE SWITCH!!

When you are on the limit of the switch PoE power output you may see that the switch seems to receive enough voltage becaus it starts when plugin in the utp cable. well, 7.2V is not the required 8V!! T

That triggers the configuration reset on the access point.
