AP 1572 not booting

Hello folks,

We have an AP 1572eac, that is not booting. When we connect the power 4 leds start do blinking simultaneously, and the AP do not boot, no console, no rommon. What's strange that if we let the AP powered off for some time, after that the AP boot for a while but after some time back to the original condition 4 leds start to blinking.

Any idea?

 

Thanks in advaced

Hello Rps,

 

Unfortunately, I am not able to get the logs, as I said It boot for few time. I´ve added the console info, that I could take before it locks again and starts do blinking all four leds. 

I see that the AP seems to be restarting in a loop.

Maybe you can try to reset, or enter ROMMON to upgrade the AP, otherwise, it is recommended to open TAC CASE, this AP may be replaced by RMA.

Hello guys, 

 

Making more tests, the problem is the internal power supply from the AP. Using the power injector works fine. So RMA needs do be done.

 

Thanks
