MDI/MDI-X Crossover Cable Wiring

Figure A-1 shows the wiring scheme for implementing a crossover cable if needed for connection to the switch’s 10Base-T or 100Base-TX ports. Such a cable may be required when connecting the switch to another switch or a hub device.

Power Cord Set Requirements

The wide-range input feature of the VH-4802 Ethernet switch permits it to operate from any line voltage between 100 and 240 VAC.

The power cord set (appliance coupler, flexible cord, and wall plug) you received with the switch meets the requirements for use in the country where you purchased the switch.

Power cord sets for use in other countries must meet the requirements of the country where you use the switch. For more information on power cord set requirements, contact your Enterasys Networks Support Representative.

General Requirements

The 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 accredited agency responsible for evaluation in the country where the power cord set will be used.

The power cord set must have a minimum current capacity of 10A and a nominal voltage rating of 125 or 250 VAC, as required by each country’s power system.

The appliance coupler must meet the mechanical configuration of an EN 60 320/IEC 320 Standard Sheet C13 connector for mating with appliance inlet on the hub.
