коммутатор Extreme Networks 220

Extreme Networks 220

Серия Extreme Switching 220 — экономически выгодное семейство коммутаторов Gigabit Ethernet Layer 2/3 с фиксированной конфигурацией, предназначенных для предприятий малого и среднего бизнеса, которым нужны ключевые функции в гибком, но простом в управлении решении.

Серия состоит из шести коммутаторов, включая 12, 24 и 48-портовые модели с поддержкой PoE + и аналогичные модели без поддержки данной функции. Все модели обеспечивают неблокируемую производительность портов Gigabit Ethernet и включают 2 или 4 порта SFP для подключения к высокоскоростным волоконно-оптическим линиям связи на скорости 10 Гбит / с. Кроме того, 12-портовые модели могут работать в режиме без вентиляторов, что делает их идеальными для офисных развертываний.

В дополнение к набору функций уровня 2, серия 220 поддерживает сервисы маршрутизации IPv4 RIP, резервный источник питания, а также стекирование до 4 коммутаторов в одно логическое устройство с одним IP адресом управления.

Серия 220 также поддерживает множество опций управления, включая облачное управление через ExtremeCloud для контроля проводной и беспроводной сети через единое окно. Коммутаторы можно также настроить через веб-браузер или используя ExtremeManagement для централизованного управления, мониторинга и устранения неполадок. А для опытных пользователей в 210 серии доступны функции управления через стандарт CLI с возможностями использования скриптов.
