Just wanted to share something i found out today. I have a Zyxel GS1910-24 gigabit switch. It has 24 ports, 4 of which are shared with RJ-45 and SFP. I bought some Zyxel specific SFP modules from fs.com and tried them out today. The only way I could get them to show link up was to manually set the speed mode to 1000-X setting. Any of there other 1Gbps settings like 1000-X_AMS or SFP_Auto_AMS would result in link down.
Is this what others have experienced too with Zyxel switches using SFP?
