Fiber Ports
MOXA EtherDevice Switch’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 connector.
Consequently, you should use fiber cables that have SC 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 2 km for multi-mode, and 15 km for single-mode) for
stallation versatility. in
Dual Speed Functionality and
Switching
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 the other 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.
MOXA EtherDevice Switch 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.
Switching and Address Learning
MOXA EtherDevice Switch has an address table that can hold up to 1K node
addresses, which makes it suitable for use with large networks. The address
tables are self-learning, so that as nodes are added or removed, or moved from
one segment to another, MOXA EtherDevice Switch automatically keeps up
with new node locations. An address-aging algorithm causes the least-used
addresses to be deleted in favor of newer, more frequently used addresses. To
reset the address buffer, power down the unit and then power it back up.
