I am trying to figure out why I am getting these error messages on my 3750E switch:
Apr 23 18:34:39: %SFF8472-5-THRESHOLD_VIOLATION: Te1/0/1: Tx power low alarm; Operating value: -32.2 dBm, Threshold value: -12.2 dBm.

Apr 23 19:04:40: %SFF8472-5-THRESHOLD_VIOLATION: Te1/0/1: Tx power low alarm; Operating value: -32.2 dBm, Threshold value: -12.2 dBm.
Any suggestions?

How about "sh interface Ten1/0/1 trans detail"?

Don't know with the other's opinion but your module (Ten 1/0/1) is has triggered an alarm after exceeding the lower treshold limit of -12.2dBm.
My recommendation is to get the module RMA-ed.
