1. Product Overview / Обзор продукта

The Enterasys A4H254-8F8T is a versatile, high-performance Hybrid Gigabit Ethernet Switch within the SecureStack A4 family. This unique model is engineered for environments that require a balanced mix of fiber and copper connectivity. Featuring 8 1000Base-X SFP ports for long-distance backbone links and 8 10/100/1000Base-T RJ45 ports for local device connections, it provides the ultimate flexibility for industrial control rooms and telecommunication hubs. With Layer 2/3/4 prioritization and Extreme’s signature security features, the A4H254-8F8T is a critical component for maintaining high-availability networks in oil, gas, and utility sectors.

Ключевое преимущество: Модель A4H254-8F8T — это уникальный гибридный коммутатор, который сочетает в себе 8 гигабитных портов SFP (оптика) и 8 гигабитных портов RJ45 (медь). Такое решение позволяет использовать одно устройство для подключения как удаленных объектов по оптоволокну, так и локального серверного оборудования. Как часть серии SecureStack A4, он обладает повышенной производительностью и расширенными функциями безопасности, что делает его идеальным выбором для модернизации сетей на критически важных объектах в Казахстане и странах СНГ.
