We have strange behavior on ports 10, 11 and 12 in a FS-124F-POE switch. In ports 1-9 there are PoE devices (phones) and are working perfectly. However, when we connect a new PoE phone to port 10 (or 11 or 12), the new phone receives PoE but the port does not link and stays down physically. We have tried to connect directly with a laptop to these ports (10,11 and 12) but they do not link. Just in case there is a problem associated with PoE, we have disabled ports 1-4 but still ports 10,11 and 12 are not working. We have version 7.0.5 in switches and 7.2.1 in controller (Fortigate 200F).
Any ideas?. Bug? Hardware problem?.
Thanks in advanced.

Hi @amguirado73
>Connect a test client to port 10
After connecting the client on port 10 , execute below command and share the output here to check the STP status, log display and if there is any crash reported
#diag debug report
Indicate that I got confused when opening the query. The ports that do not work are 11 and 12. Right now the test device is connected to port 11 and report has been generated. The switch has been rebooted but the issue still exists.
Thanks again for your help.
Just making sure you have ruled out cabling as the issue? Does port 11 and 12 not work even if using a known-good cable (i.e. cable that is used to connect devices to the other working ports)?
Hello,
I have just repeated a new test:
new cable and laptop -> Port 11 -> No link
new cable and laptop -> Port 12 -> No link
new cable and laptop -> Port 13 -> Link Ok
There is no link in port 11 and 12 but when you connect a PoE device, it receives energy and link is always down.
I think that could be a bug associated with PoE ports. Ports 1-10 are used by Cisco phones.
Thanks again.
Same issue here with a FS-108F-FPOE
Did you resolved your issue?
The port have worked for several days, and just suddently stopped working. POE is delivered on the port.
