LED Indicators
The front panel of the Moxa EtherDevice Switch contains several LED
indicators. The function of each LED is described in the table below.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the EDS’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 the EDS to Ethernet devices.
Dual Speed Functionality and
Switching
The Moxa EtherDevice Switch’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 ports where it is
not needed. Packets that are used in maintaining the operation of the network
(such as the occasional multi-cast packet) are forwarded to all ports. The EDS
operates in the store-and-forward switching mode, which eliminates bad
packets and enables peak performance to be achieved when there is heavy
traffic on the network.
