Hardware Overview
??A cross-overcable is used to connect like ports: MDI ? MDI or MDI-X ? MDI-X.
For example, you should use a straight-through cable to connect your computer’s Ethernet NIC to a HUB or switch, but use a cross -over cable to connect your computer’s Ethernet NIC to another computer’s Ethernet NIC.
Fiber Ports
MOXA EDS-508’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, 40, or 80 km for single-mode) for installation versatility.
