Strange log message. Is this an error?

Hi @Zyxel_Judy

Now… I have two different PoE log errors logged in this thread. 

First log error:
“Port Detection Status is Searching”
“Port Detection Status is Delivering Power”

Result of first log error:
The two actual ports did not flap down and up again
Attached units did not reboot
Attached units did not drop traffic

Second log error 30 days later:
“PoE power usage exceeds 95% threshold, remaining power is 0.0W”
“PoE power usage is less than 95% threshold, remaining power is 324.6W”
(ONE second between these messages)

Result of second log error:
No PoE powered devices got problems or was powered down
Attached unit did not reboot
Attached unit did not drop traffic

This second PoE error has been seen before in march by two other persons. You offered a RMA for that person at that time, but he rejected it with the argument “Given that you couldn't replicate the problem and therefore have no fix, a replacement may suffer from the same issue.” (I did chat with one of the two that have seen this log with high PoE usage in the forum chat). To note is that he has not seen this message again.

As it is simply impossible during these circumstances that the power draw would go from my std approx 49W to momentarily over 95% of the switch max 375W which would be an increase of more than 7 times normal power usage, it must be either a hardware issue or a software bug. But… As no problem at all was seen with power or actual traffic on the switch ports, well, that could lead to not suspect hardware, but software/firmware!

As this switch model has been around for a while and this log message has be up in the forum before with at least two different persons except me, I do wonder why you do not go through the firmware code and look at what in the code that actually triggers this log message. Just to offer an RMA when you have no clue if the same log message will/can appear again in the new replaced hardware, well, that bothers me… Just a response with “we are unable to replicate that problem” and offer an RMA, that bothers me. 

I do very much appreciate that you took the time to look into the switch, but I am not satisfied with that you take it so easily.

I will in this case not go on with an RMA as I have not had any real issues except the log messages that you cannot explain. But if I will see any more of this log messages I will probably try to move away from this switch and replace it with something else. I.e send it back to where I bought it. It is simply too much for me with two different PoE log errors directly after moving to this Zyxel switch that you cannot explain and take so easily.

B t w… My switch has Hardware Version: V1.19. Do you have any newer hardware revision?

Do you have any on-site fix/replace if paying for it?
How long will the RMA take?
How will my existing CLI license be added to the new device?
Is it possible to have another switch in advance? I can pay for en extra switch and get a refund when you receive the RMA unit.

PS
I asked above…." I do wonder why you do not go through the firmware code and look at what in the code that actually triggers this log message.". Again… what in the firmware code will cause these log messages? Line voltage fluctuation? Is it possible for you to reveal what and how the triggers in firmware causes these log messages?
* “Port Detection Status is Searching”
* “Port Detection Status is Delivering Power”
* “PoE power usage exceeds 95% threshold, remaining power is 0.0W”
