Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect EDS-316’s
10/100BaseTX ports to any kind of Ethernet device, without needing to
pay attention to the type of Ethernet cable being used for the connection.
This means that you can use either a
straight-through
cable or
cross-over
cable to connect EDS-316 to Ethernet devices.
Fiber Ports
Moxa EDS-316’s fiber switched ports operate at a fixed 100 Mbps speed
and full-duplex mode to provide the best performance. The fiber ports are
factory-built as either a multi-mode or single-mode SC/ST connector.
Consequently, you should use fiber cables that have SC/ST connectors at
both ends. When plugging the connector into the port, make sure the
slider guide is positioned to the right side so that it fits snuggly into the
port.
The 100 Mbps fiber ports are switched ports, and perform as a domain,
providing a high bandwidth backbone connection that supports long fiber
cable distances (up to 5 km for multi-mode, and 40 km, and 80 km for
single-mode) for installation versatility.
Dual Speed Functionality and Switching
Moxa EDS-316’s 10/100 Mbps switched RJ45 port auto negotiates with
the connected device for the fastest data transmission rate supported by
both devices. All models of Moxa EtherDevice Switch are plug-and-play
devices, so that software configuration is not required at installation, or
during maintenance. The half/full duplex mode for the switched RJ45
ports is user dependent and changes (by auto-negotiation) to full or half
duplex, depending on which transmission speed is supported by the
attached device.
Switching, Filtering, and Forwarding
Each time a packet arrives at one of the switched ports, a decision is
made to either filter or forward the packet. Packets with source and
destination addresses belonging to the same port segment will be filtered,
constraining those packets to one port, and relieving the rest of the
network from the need to process them. A packet with destination
address on another port segment will be forwarded to the appropriate
port, and will not be sent to the other ports where it is not needed.
