MISMATCH (Power Filter Mismatch)
The Power Filter Mismatch alarm indicates that the two power filters do not have
matching current carrying capacity or do not match the preprovisioned filter type. The
Power Filter Mismatch alarm could also indicate that power filter Wavelength Tracker
function does not match the shelf Wavelength Tracker mode. This alarm can also occur
after a new installation on a PSS-32 drop shelf configuration.
