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-8TX1UM/VH-8TX1MF 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.

VH-8TX1MF, VH-8TX1UM specifications

Enterasys Networks, a well-respected name in the field of networking technology, has introduced the VH-8TX1UM and VH-8TX1MF models, which cater to the ever-evolving needs of modern enterprises. These devices are designed to enhance connectivity, improve network performance, and provide enhanced security for users across various environments.

The VH-8TX1UM model is a versatile Layer 2/3 managed switch that features eight 10/100/1000BASE-T Ethernet ports. This configuration allows for seamless connectivity with existing network infrastructure while providing the necessary throughput for bandwidth-hungry applications. It supports a range of features including VLAN tagging, port mirroring, and link aggregation, making it ideal for both small and medium-sized businesses looking to scale their networks without significant hardware investments.

Meanwhile, the VH-8TX1MF model is designed with a focus on modularity. It not only features eight Ethernet ports but also includes slots for additional modules, allowing organizations to customize their network setup based on specific requirements. The modular design ensures flexibility, enabling future upgrades without the need for complete hardware replacements. This characteristic is particularly beneficial for companies that anticipate growth or changes in their network architecture.

Both models boast advanced technologies such as Quality of Service (QoS) and Power over Ethernet (PoE). QoS prioritizes critical network traffic, ensuring that voice and video applications receive the bandwidth they need for optimal performance. PoE allows for the powering of devices like IP cameras, phones, and wireless access points directly through the Ethernet cables, simplifying installations and reducing the need for additional power sources.

In terms of security, Enterasys equips the VH-8TX1UM and VH-8TX1MF with robust features to safeguard sensitive data. These include access control lists and port security settings, which protect against unauthorized access and mitigate potential threats. Additionally, the switches support network management protocols such as Simple Network Management Protocol (SNMP), enabling efficient monitoring and management of network performance.

Overall, the Enterasys VH-8TX1UM and VH-8TX1MF models stand out with their combination of performance, flexibility, and security. They present a compelling option for enterprises aiming to enhance their networking capabilities while ensuring that they are well-equipped to handle future technological advancements. Businesses investing in these switches are sure to benefit from a solid foundation that can evolve with their operational needs.
