Hallo to everyone!
I have problem with optical link between core and WAN segments.
Here is situation:
I use Catalyst 3750E(ver c3750e-universal-mz.122-52.SE) as core switch and Catalyst 6504E(ver adventerprisek9_wan-vz.122-33.SXI6) as WAN switch. After changing optical transceiver from sfp 1000BaseLH to X2 10G 10Gbase-ER in syslog I found this:
%SFF8472-5-THRESHOLD_VIOLATION: Te2/0/2: Voltage low alarm; Operating value: 0.00 V, Threshold value: 2.96 V.
%SFF8472-5-THRESHOLD_VIOLATION: Te2/0/2: Rx power high warning; Operating value: 1.0 dBm, Threshold value: 0.5 dBm.
This message appears every 10 minutes… Physical layer is checked(and SFP on this link worked perfectly). I already changed IOS on c3750e-universalk9-mz.150-1.SE3.bin(CSCts58073 Bug Details
), but problem still appearing.
Here is transceiver detail:

Please, could you help me to understand what is wrong with this config…
Best regards.

I get this alarm all the time. I just ignored it.
No line errors, no link flapping.

Thanks for replay, but may be you have advise how to switch off this message from syslog... It is pretty annoying
