AP250 stuck in boot loop with orange LED.

[Jay5]

I've got a small Connect network with 3 x AP370s and 1 x AP250. The AP250 is stuck in a boot loop with orange LED showing all the time. Below is the output of the console during boot. Any ideas?

1. Check the power supply.
2. Perform a hard reset (power cycle).
3. Check for firmware updates and install if available.
4. Consider a factory reset (backup data first).
5. Contact the manufacturer's technical support for assistance.
6. Inspect for physical damage or loose connections.

Of course, I've sent you an email with directions on how to open a one time courtesy case so we can assist you with that TFTP flash.

[Jay5]

Thanks for that Sam. Unfortunately these are using Connect licenses and I don't have access to log a case. I can confirm that the boot can be interrupted at both of the possible prompts. Are you able to facilitate raising a case, either for TFTP or RMA? Thanks.

[samantha_lynn]

If you are able to interrupt the boot cycle when it prompts you to hit any key to stop the autoboot process, then you'll want to file a case with support so they can try a TFTP flash with you, to see if we can get the AP to stabilize. If you can't interrupt the boot cycle, then you'll want to file a case to request an RMA.
