Dears.
I have a catalyst 9407 switch,with SUP-1XL which i tried to insert a GLC-LH-SMD tranciever into it.
The tranciever was detected as "inserted", but when i connect the fiber cable to it, it just did not came up.
Any idea

SFP-----Light--------------No light ---patch
SFP-----No Light-------------Light ---patch
