SG300-28 SFP

[Random44F]

Hi All,

I am trying to use SFP module from one transceiver to the cisco switch . I have a general sfp device which the lighs turn on when plugged in from port 28 to 27 which are sharfed sfp but do not work if port 28 is connected to another fiber transceiver.

Any ideas, what the issue can be ?

I suppose I don't need to buy a cisco sfp as the current one which is from COMM 1 seems to work if plugging port 27 and 28 directly (loop)

Thanks for all inputs
