ES42 Series Edge Switches Installation and User Guide (05/05)
4.0 OPERATION
4.1 Dual-Speed Functionality, and Switching
The Magnum ES42 Series Edge Switches provide SIX switched ports
with combination of fiber and copper or copper only. The architecture supports a dual
speed switching environment, with standard auto-negotiation capability.
The switched RJ-45 ports are full- or half-duplex auto-sensing for mode and
speed, and auto-cross for plug polarity. (See Section 4.2). When the connected device is 10
Mbps, the ES42s obeys all the rules of 10 Mbps Ethernet configurations. The 10 Mbps
users can “communicate” with 100Mbps users as well as other 10 Mbps users through the
switch. Similarly, the 100Mbps traffic obeys the rules of 100Mbps Ethernet, and can
communicate with 10 Mb and 100Mb users. Magnum ES42 Series units are plug-and-play
