Hello! I have SG-200-50 (FW 1.3.7.18 Boot 1.1.06) and SG-200-18 (FW 1.3.5.58 Boot 1.3.5.06).
Have 4 Mini-Gbic ports in inventory: 2 Linksys MGBSX1 and 2 Cisco GLC-SX-MMD
When I try to connect switches between 2 Linksys MGBSX1 in ports (GE49-GE17) I got fail. Link Down, port in 1 switch reports that no Loss of signal.
When I try to connect switches between 2 Cisco GLC-SX-MMD in ports (GE49-GE17) I got fail too (Link UP, but mass packet loss).
But when I'm try to connect MGBSX1 + GLC-SX-MMD (GE49-GE17) - Link UP, everything just perfect.
How this is possible?
And also, I'm understand, that in original switch manual GLC-SX-MMD is not in supported modules, but it have DOM and DDMI support, that showns in SG200 optical module test (Temperature, voltage, current output power, input power).
