Hi,

after updating the firmware on my SG3210X-M2 switch to version 1.0.11, the log on my Omada Software Controller (version 5.15.20.20, Linux/Docker) reported the following warnings and alarms:

• The voltage of the SFP module on ??-??-??-??-??-??'s port Te1/0/9 is lower than warning point.
• The voltage of the SFP module on ??-??-??-??-??-??'s port Te1/0/9 is lower than alarm point.

These entries appear in the "Resolved" section of the logs every 5 to 30 minutes. Consequently, the log is flooded with these entries. The SFP port and module seem to be working properly; network connectivity and bandwidth are fine.

Reverting to the previous firmware version, 1.0.7, will make the DDM warnings/alarms disappear.

Is this a firmware bug, and/or how can I get rid of these warnings and alarms? Should I revert back to firmware version 1.0.7 and wait for this issue to be resolved?

Hardware information:

• SG3210X-M2 Switch (8 Port 2.5G, 2 Port SFP+), hardware version v1.0
• TL-SM5310-T SFP+ 10G Base-T SFP+ Module

Regards,

Christof
