The M12000-24SFP/12GT-EA service module's 12 front ports are fiber/copper combo ports. Each SFP port
is corresponding with a combo 10/100/1000BASE-T port. Only one port can be used at a time. The
automatic MDI/MDI-X identification function of the 10/100/1000M electric port takes effect only when
auto-negotiation is enabled.
The M12000-24SFP/12GT-EA supports 1000BASE-X and 100BASE-FX modes. Please configure the ports
according to the Ruijie Networks configuration manual.
