Page 25: Mdi/Mdi-X Auto-Crossover
Nexans Active Networking Systems Industrial Ethernet iSwitch 74x MDI/MDI-X Auto-Crossover MDI/MDI-X Auto-Crossover is an optional function of the IEEE802.3 standard which is specified in its Chapter 40.4.4. The aim of this standard is to eliminate the need for crossed connecting cables between Ethernet devices. - Page 26 Nexans Active Networking Systems Industrial Ethernet iSwitch 74x Note: Over the past years quite a number of manufacturers such as CISCO, Alcatel etc. have introduced proprietary PoE solutions into the market which differ from the standard. In this case caution is required. However, within the framework of our flexible options some of those adaptations are possible (see Options).
