Cannot turn on PoE for Ring Doorbell port on ICX 7150-C12P

[KenB2386]

I have one of the first 2018 Lennar smarthomes in our community with this switch, 2 APs, and a RING doorbell. They worked fine for 5 1/2 years and I had never tried to check anything until now. It appears to be running 2017 switch firmware.

This winter, the doorbell went offline while we were away for a long time. The APs are still working. The switch has no IP address so I finally got connected via the serial port and the inline power command shows Class 3 PoE ON for the 2 APs. 

The management status of ports 1-6 is ON. Port 2 where the doorbell cable connects is marked as non-PD. When I try to configure the port 2 for class 3, I get a warning that the configuration for that port was not changed.

What does that mean the problem probably is?

Does it mean the doorbell cable is trying to draw too much power?

What is the best way to troubleshoot the problem?

I assume the fact that the switch has no IP address is not related to this problem and will work on that separately.  I have no idea if it ever had one.

Thanks.

OK. So now you know you should always find out what version of firmware the switch has before providing instructions, right?

And, you did not tell me whether or not to expect all ports to have PoE turned on if I proceed as is.

I imagine you are in a hurry but I don't ask questions I don't want answers to.

Thanks.

Hi @KenB2386 

If your Switch is not on an new version those commands will not be executed. It's that simple.

We are technically trained and experienced to assist our users, we always know what's the best practice.

However, please perform upgrade of the Switch. We cannot help you further before you trying upgrade your Switch or not following the assisted troubleshooting steps. Of course you can ask questions.

Thanks.

Hi @KenB2386 

There are some issues/bugs in the non-UFI versions and the PoE issue is one of them. That is the reason we assist in upgrading the Switch to a recommended version to get over such issues.

There are no changes required before the upgrade. 

Please let me know if you have any queries.

Thank you again.

That was my point. Best practice should be to make sure you know what version of switch firmware the user has to make sure you give instructions that work with it. I told you in my initial post it was 2017 vintage firmware and you gave me instructions what don't work on that.

And, yes, you say I can ask questions but I seldom get actual answers and I have noted other users saying likewise.

I have done the upgrades and believe things are working.  Since you did not answer my question about how PoE would turn out, I will assume you did not know. 

08080f upgrade ended with PoE messages that ports 4 and 6 were enabled. No mention of port 2.

08095h upgrade ended with "show inline power" showing all 12 ports enabled and ports 2, 4, 6 being powered.

BTW: I noticed several TFTP session timeout messages during that version's updating of slot 1 firmware. I did not see that during 08080f upgrade.

Thanks for your help.

I hope you will consider my suggestions.

Hi @KenB2386 

Thank you for the update.

Please check my previous response mentioned that PoE issues from the non-UFI versions are resolved in UFI Versions. Upgrading the Switch with UFI version only is the key solution for the PoE issues and for some other bugs. 

I think you missed my last response or misread it once again.

Your question 'how PoE would turn out?' is a hardware-related process. We are the Technical team on this forum to troubleshoot the Switch software-related issues and NOT Hardware issues.

If any hardware issues arise in the future, you can reach out on this forum and we are happy to assist with replacements (RMA).

However, as it was mentioned upgrading the Switch resolved the issue. Good to know about it.

I appreciate your attention to learning about PoE (Power over Ethernet) in detail. Please refer to the below link which can help you understand how it works.
