74 Technical Specifications ELS100-24TXGMDI/MDI-X Crossover Cable WiringFigure A-1 shows the wiring scheme for implementing a crossover cableif needed for connection to the switch’s 10Base-T or 100Base-TX ports.Such a cable may be required when connecting the switch to anotherswitch or a hub device.Figure A-1. External Crossover Cable WiringPower Cord Set RequirementsThe wide-range input feature of the ELS100-24TXG Ethernet switchpermits it to operate from any line voltage between 100 and 240 VAC.The power cord set (appliance coupler, flexible cord, and wall plug) youreceived with the switch meets the requirements for use in the countrywhere you purchased the switch.Power cord sets for use in other countries must meet the requirements ofthe country where you use the switch. For more information on powercord set requirements, contact your Cabletron System SupportRepresentative.General RequirementsThe requirements listed below are applicable to all countries:• The length of the power cord set must be at least 5.00 feet (1.5 m)and a maximum of 6.56 feet (2.0 m).• All power cord sets must be approved by an acceptable accreditedagency responsible for evaluation in the country where the powercord set will be used.• The power cord set must have a minimum current capacity of 10Aand a nominal voltage rating of 125 or 250 VAC, as required by eachcountry’s power system.• The appliance coupler must meet the mechanical configuration of anEN 60 320/IEC 320 Standard Sheet C13 connector for mating withappliance inlet on the switch.
