SG300-28PP combo port not working on optical, fiber gbic

[coolbabar]

Hi 

I bought 3 used SG300-28PP. With each I have the same problem. All combo ports work well on copper but not on Fiber. 

I used different gbic types that work in my other sg300 switches. No mather that switch is configured od not or it have a program copy from another that works. Then fiber cable is connected the port is forced to work on fiber insted of copper and the two green light on port starts to blink together in slow 1/2s cycle. In logs the port is going up and down.

Do you have some sugestions? How to make it work or what is wrong?

Hi,

My name is Ritesh Sharma from Cisco TAC.

Please check the module model number you are using with the fiber cable, the module should be supported by the switch.

Please find the link below for the datasheet of the switch where you can check all the supported Modules:

Please mark this as helpful if it resolves your query.

Hi.

Thank you for the replay.

The link is to the support page...

Can my other cisco sg300 support different fiber modules? Like I said before with other SG300 my modules are working.
