Tags: #hardware
Model: ER8411  
Hardware Version: V1
Firmware Version: 1.3.6

Current configuration:

SFP1 WAN

SFP2 Uplink to 10G Aggregation Switch

All other ports disabled.

 

 

After reboot, SFP3 LED lights up, even though the port is disabled and nothing is connected (not even an SFP module is installed). The only way to get the LED to turn off is to turn the port on, then back off. LED then turns off and stays off.

  @dinosaurscuba 

Can this issue be reproduced consistently? Do ports other than SFP3 exhibit the same behavior? Does it only appear after a reboot, or does it never occur under normal conditions? We haven’t received similar reports before; the LED-indicator symptom looks like a possible hardware defect. If you’re concerned, please contact support to arrange a replacement.

  @Ethan-TP Yes it can be reproduced consistently. No other LEDs have the same issue. I didn't even notice right away because I would assume all LEDs operate correctly. I don't believe it is a hardware issue, but maybe it is.

  @Ethan-TP I don't think it's a hardware issue with the LED. When rebooting the router, there is traffic shown on that port, even though no SFP module is installed, and the port is disabled.
