There are chances of HW bug at 3750x, but you need to test it if you can

Try to check the same SFP port with any other cisco switch and see what happen after power re-cycle

If everything ok that means other end  i.e. siemens switch has some issue.

 

Have you tried to reset the port after power re-cycle? what are the observations ??
