XGS4600 - SFP+ Transceivers stop transmitting light

@Zyxel_Lucious

Thanks for that however if that's the case please can you try to explain why the problem doesn't occur on the 52f variant of this switch line-up when we're using the exact same optics with it.

Surely if we was buying unsupported transceivers then we should see issues across the xgs4600 range.

Thanks
Matthew
