@Vincent-TP Hi, thanks for replying!

I've always had the LED set to On:

However, the EAP787 has no visible LED at all nonetheless.

Hi  @jdrch 

Thanks for the reply.

That's weird. How many EAP units do you have in total? Are they all off?

Is the Internet working correctly?

If convenient, would you please share a picture showing the LED status?

  @Vincent-TP the only EAP I have is the one in the screenshot. It's on and operating. I'll take a pic and upload it later.

Hi  @jdrch 

Thanks for the reply.

Please try Force Provision.

BTW, how did you power on this EAP787?

  @Vincent-TP Here's the picture you requested, showing the EAP787 beside the UniFi UAP-AC-HD. As you can see, the UniFi AP's LED is on, while the EAP's isn't:

I'm very hesitant to Force Provision the EAP as I've already had to adopt it twice. The 1st time was during initial setup, the 2nd was last week when it got stuck in Adopting mode after I converted Omada Controller to run as a service on Windows. 

The EAP is powered by a POE switch.

Hi  @jdrch 

Thanks for the picture.

Under normal circumstances, a force provision typically does not cause any issues. During this process, the EAP will briefly restart and lose connectivity, as the controller pushes the configuration again.

I think you should try this during a period of low network usage. Additionally, please let me know the model of the PoE switch. Is it a TP-LINK model?

@Vincent-TP the POE switch is a NETGEAR GS316PP.

  @jdrch 

Thanks for the info.

Is the switch's POE budget sufficient?

An LED that is lit up is a fundamental feature for an EAP. It is likely a hardware issue with the EAP's LED.

You may contact your retailer to check the EAP's warranty.

Before doing so, it is advised to reset the EAP and run it in standalone mode to check whether the LED lights up. This step is to rule out any improper configurations in the controller.

@Vincent-TP Good question about the POE budget. I checked and it turns out the EAP787 is a PoE++ device while the switch it's connected to is PoE+. The switch claims to be able to provide 30W/port, but the specs sheet says even at that level it delivers a max of 25.5 W to the device. This is less than the 29W in the EAP787's specs.

I've ordered a PoE++ switch to see if that makes a difference. Thanks!
