Hi

Anyone that knows what this means? I have not seen any link up/down. Happened 9 days ago on one port. And yesterday on two ports. Hardware fail? The switch is just 2 weeks old.

    Hi @peos42 ,

    From your description and the logs, it seems like you're experiencing some PoE (Power over Ethernet) issues with your switch, particularly on ports 6 and 7. Please try these troubleshooting steps:

    Check Physical Connections:

    • Try using different Ethernet cables to rule out cable issues.
    • Connect the affected PoE devices (PoE Access point, PoE camera...) to different ports (not port 6 & 7) to determine if the issue follows the devices or stays with the original ports
    • Connect different PoE devices to ports 6 and 7 to see if the behavior persists

    Verify PoE Requirements:

    • Confirm the power requirements of your connected devices are within the switch's PoE capabilities
    • Check if the total PoE power consumption is within the switch's power budget.

    Hi

    This is a PoE++ Switch. So the changes you connect devices that are out of spec wont exist…. Port 6 is a class 0 device and takes 4.8W (A cisco 8 port switch), Port 7 is a class 0 device and taks 2.6W (Axis outdoor business camera M3026-VE). Just checked the power values. Totat power used on switch is 46W at the moment. I.e almost nothing…

    Now @Zyxel_Judy … The chance that several ports at the same time will have trouble because of of cable issues is zero to none. I replaced a netgear switch recently with this Zyxel XS1930-12HP and have only moved the 1 feet patch cables between the patch panel and the switch over to the new Zyxel. Nothing else touched. So you could take away cable problems. And the Netgear Prosafe has run flawlessly and delivered PoE on these cables for two years with no problem. Now with the zyxel this log came up after just a day on one port and the again days later, but on two ports. The switch has only been used for two weeks.

    It is for sure switch related!

    However… I have not seen any link up/down. Yet…. The ports logging this "PethPse" seems to have uptime in hours since I connected it to the port and did not flap up and down when his message occurred.

    Is this new switch about to fail?

    //Peo

    Hi @Zyxel_Judy

    Just a note it that I cannot see any practical issues so far. And not any port flapping. All seems to work ok. But those messages worries me…

    A start is that you tell me what that message actually mean. Is it a software bug, is the switch about to fail even if it seems to work ok, or what? I can for sure say it is not that several cables are bad, just like that, when just replacing the switch to Zyxel :)

    I sent you a full tech support file as a private message. Please let me know when you have investigated it.


    PS
    Just an extra note. Maybe you should create a ticket for change so that you give low priority in the switch kernel when generating tech support file. This tech support generating can for sure affect switch connected devices as CPU goes 100% for a minute… But DONT focus on this! This is just a side note. You probably don't generate this that often…

    Hi @peos42 ,

    The logs you've seen are related to the PoE issue. Since you mentioned not experiencing any practical problems, could you clarify if you're using adapters for the Cisco switch and camera?


    If you're not using adapters, please try enabling Force AT mode on the affected ports (Ports 6 and 7) on the switch to see if the PoE logs gone.

    The path: PORT > PoE setup

    Hi @Zyxel_Judy

    As I have sent the tech report I guess you can se the switch is delivering power. So to be clear… I am not using any PoE injectors. The Zyxel Switch is delivering power. And before it was my old switch with no problems for years.

    Now… The switch ports did not flap up and down when these messages appeared. And they did not loose power. So the port uptime as well as the hardware powered have uptime that is longer than the time since that log message. So again…. I have not had any problems. But still, it worries me and I want to know…

    What does these log messages mean? I guess the "Pse" part stands for "Power Source Equipment", i.e and end device that is powered.

    Is the log message logged when the voltage on the AC side fluctuates to much?
    Is it a bug in the Switch OS code?
    What in the code triggers the messages?
    Or will it indicate I will see a hardware failure soon?

    Tnx in advance

    Hi @peos42 ,

    Based on the information collected so far, it seems that the XS1930-12HP generates the PoE log messages while the Cisco switch and camera use the switch's PoE functionality without actually losing power. This differs from the scenarios we've encountered previously.

    At this point, we cannot determine the root cause of the log messages from the current data alone. To investigate further, could you provide remote access to the switch, TeamViewer access information, Switch IP address, and Switch password?


    This would allow us to collect underlying data and conduct a deeper analysis.
    For security, please send these details via private message (My Account > Message).

    Hi @Zyxel_Judy

    I'll send you a direct message…

    Hi again @Zyxel_Judy

    There is for sure something strange with the switch. Either switch hardware or switch firmware… Normal PoE consumption is around 47W according to "show pwr". However… this came "just like that" in my syslog today and lasted for one second…

    2024-12-29T10:18:39Z switch0.incedo.org system: PoE power usage exceeds 95% threshold, remaining power is 0.0W
    2024-12-29T10:18:40Z switch0.incedo.org system: PoE power usage is less than 95% threshold, remaining power is 324.6W

    For one second the switch logged max PoE. And note that nothing was done at that point with administration or anything else done by me. Actually most units was idle and almost no network traffic. Also.. Like before with the other messages regarding PoE that you are about to investigate, no portflap or so. All units feeded with PoE still works without downtime. I.e not affected by this log event. So again…. I have not seen any practical issues (yet) that affects the network or its connected devices except the logged messages regarding PoE. First "Port Detection Status is Delivering Power" and "Port Detection Status is Searching". And now 20 days later this "PoE power usage exceeds 95% threshold"…

    The command "show hardware monitor C" also shows the fans have not increased its rpm either…
    FAN Speed(RPM) Current  Max  Min Threshold Status Detect

    FAN1    3837 3870 3763       500 Normal        
               

    FAN2    3731 3752 3641       500 Normal  

    As a note…
    PoE powered devices are:
    (Same 7 devices and cabling that was connected and powered with my old switch without any issues or strange logs)
    1 - Aruba AP 505
    3 - Aruba AP 535
    2 - Cisco SLM 2008 8-port switches
    1 - Axis M3026 Outdoor CAM

    What is going on? Switch hardware about to fail or firmware bugs? Seems that several others have had the very same logs… https://community.zyxel.com/en/discussion/21634/xs1930-12hp-weird-poe-warning-log

    This switch has been on the market for a while. So you have had the time to do revision updates on the hardware as well as making the firmware stable. The link I refer to above is 9 months old… Have you just dropped that investigation? Now I have there very same logs… This is NOT fun.

    Hi @peos42 ,

    When we accessed to your switch, there was no mentioned log anymore. Since we are unable to reproduce the issue at our facility, so you can continue using the switch while monitoring for any recurrence of the log errors. Alternatively, you may initiate the RMA process if you prefer to replace the unit.
