AT-PB100 Series Media Converter Modules
PB101 PB102 PB103/1 PB103/2
LED State 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.
