My HEX S SFP cage is a bit off-centre in its front panel opening. After opening the unit, I can see the SFP cage is not properly seated on the PCB, that is, it wasn't properly pushed all the way down onto the PCB, which is why it's higher than it should. It is also offset to the right and I can't understand how that's possible since the PCB holes should be in the right place, and I've seen pictures of this product where the cage is centred left-to-right. Odd. I just thought I'd mention this so Mikrotik improves their Q.C, the connector should be centred.
