Has anyone else noticed that on X695 (and probably VSP7400 as itās the same hardware), SFPs can be impossible to remove? The same SFP can work with no problem in other switches but in X695, they are often stuck. Hopefully this is a problem with only some batch and not too wide-spread.
We see the problem with SFPs from multiple vendors, including original Extreme branded SFPs that are indeed original parts, not fake.

Hi Sam!
Weāre sending one of the problematic switches in for analysis. Iām done with mine and my conclusion is that the cages are out of tolerance, probably in at least one batch of switches. We have used Extreme original SFPs and had them stick in the cages in the X695 but working flawlessly in an X450-G2. If they find a field fix for it or if we need to RMA them all is anyoneās guess. Extreme seems to have accepted this as a defect in some respect.
If this happens to any reader out there, the trick to free the SFP is to gently push it upwards (if you have the SFP in front of you and itās in the top row) and then pulling the SFPās lever to release it. This displaces the SFP just a tiny little bit, enabling the āforkā in the SFP to get in under the retainer (metal ātongueā in the cage) and free the SFP. If thereās an SFP in the port under (or over) the stuck one, pushing up on the SFP is impossible. Instead, a very gentle twist with a screwdriver between the SFPs will lift the SFP that half millimeter that is needed.
There are at least three different mechanisms in SFPs (Extreme has them all in various models) that lock them in place and release them. Only one type is problematic in the defective cages, but this type is used in both some old 1000Base-LX/SX without SSH and in some brand new 10G optics.
