(OP)
I just purchased a couple of third party GLC-SX-MMD transceivers. When I put them in, I get the following error:
%SFF8472-5-THRESHOLD_VIOLATION: Gi1/0/50: Tx power low alarm; Operating value: -40.0 dBm, Threshold value: -13.5 dBm.
When I do a SH INT TRANS I get the following:
Do the -40 dBm levels suggest defective/incompatible 3rd party transceivers or am I doing something wrong? This is the first time I've used an SFP port. Everything appears to be keyed, so I can't be physically plugging it in backwards (without causing some obvious damage).
I tried to use the 'service unsupported-transceiver' and 'no errdisable detect cause gbic-invalid' but that didn't seem to make a difference.
Thanks for any suggestions!
