I am connecting a device CWDM against a Cat4507 and I am not able to connect any interface about the frequency 1510. Toward under OK it works, but have more than enough and the 1510 don't even work.... somebody has experience with the equipment?... according to documentation it should not be necessary to use atenuador, but in other doc says that yes..... some idea?
I don't find information on this message in Cisco.
