Hi I installed 1m DAC between RB2011 and CCR1009. It clicked and now I don't know how to pull it out. I tried dragging this black latch but it doesn't seem to work and latch looks quite fragile I don't want to damage it.

I found some instructions about 40G qsfp modules that you should push cable and pull out latch but I think it doesn't work here

You need to pull down that small locking mechanism on bottom of the sfp cage with some tool. It holds down the module. When it's in lowered position then you will be able to remove the module.

Thanks it worked
