What is the physical port type? Fiber or copper? Are your cables long enough? I believe that there is a minimum length allowed. Try using cables at least 1 meter in length. If you are using transceivers, please give the model number(s).

If you're using singlemode fibre patch leads kevinhsieh is absolutely right.  You'll need a longer cable than 1m though - I'd suggest at least 10m.

It tells that fibre is too short or too good or LED in other end is too bright.
Just reduce logging level and sleep calm ;)

Are you going to be relocating one of the switches?  I notice one of your switches is called NWP-TEST-3750-X-1.

If so, the length of the fibre may well attenuate the link enough to stop the warnings.  If that doesn't sort it I'm sure the only other option is to RMA the SFPs.

Probably it is more practical to attach SPF which sends light too strong to longer cable run...

@gheist - what do you mean?  The warning is a high RX power warning, so I've suggested moving the switch (to use a longer patch lead) to attenuate the signal.

Using a SFP which sends too much light will just make the error continue.

...or do we have our wires crossed??  (You see what I did there? :-))

With longer cable run it is more likely to attenuate light more, just that having 50m roll around server room is not the best investment in infrastructure ;)

That's why I said "Are you going to be relocating one of the switches?" :-)
