Hello there,
Would it be any specific reason why SG500 switch would not accept a proper Cisco SFP copper module (GLC-T). The only log line that I can see is :
%NSFP-I-SFPGibicDetected: gi1/27 SFP port is present
But even if there is apparently no error, I can't get a connection on it. Result is the same with a non Cisco one.
Is there any limitation ?
