Description
DUP
Green
Gray
The media converter is operating in full-duplex mode.
The media converter is operating in half-duplex mode.
ML
Green
The Missing Link feature is enabled.
Note -
The Port A Mode parameter for these modules has a fixed value of 'full' and cannot be
modified.
Note -
The current firmware version does not allow the Port B Mode parameter to be set to 'full'
from the default value of 'half'. Likewise, it cannot be set to 'half' if it was set to 'full' using the
Omega interface.
Note -
Expect the DUP LED to be green when it should be gray and vice-versa when the Port B
Mode parameter is set to 'auto'. This is because the current firmware version is unable to provide
information on the negotiated mode for Port B.
