SFP module stops functioning after power outage

[andrea.sotirov1]

Hello,

I have a problem with the SFP module on my C3750 Switch. There is a File Server connected to one of the ports on the module (there are 3 Gi ports) and whenever there is a power outage the module stops working and there is no access to the File Server, i thought the port that the SFP module was currently connected to might be damaged (Gi1/0/1) so i switched to Gi1/0/2 it worked fine until another power outage occured. 

Currently i have pluged the File Server to a Fe port on the switch and when there are power outages the File Server keeps functioning after them, the problem with the Fe ports is that they are segnificantly slower :(

Any ideas waht might be causing this?

10x in advance

Hi,

So, this only happens for fiber ports but works fine with copper ports?

Have you tried replacing the fiber patch and/or the SFP?

Hi,

Yes i have tried replacing the fiber patch and the SFP but whin no effect, after power outage the File Server still loses connection until i restart the device, that made me confident that its not a hardware issue with the SFP modules or the fiber patch.
