Características y ventajas

  
Conectividad Gigabit Power over Ethernet de alto desempeño, segura y preparada para voz
El 3Com® Switch 4500G es un switch 10/100/1000 Ethernet agrupable en cluster que proporciona una conectividad de LAN segura y flexible, así como funcionalidades avanzadas optimizadas para voz tales como VLAN automática de voz y QoS. El soporte de enlaces ascendentes 10-Gigabit opcionales mediante módulos de conexión local o transceptores XFP proporciona conexiones de alta velocidad con otros dispositivos equipados de forma similar.

El Switch 4500G ofrece switching de Capa 2 y routing dinámico de Capa 3, así como robustas funcionalidades de seguridad, Calidad de Servicio (QoS) y administración para proporcionar una conectividad de extremo inteligente para las aplicaciones empresariales esenciales. Este switch ofrece una escalabilidad apilable con administración mediante una única dirección IP. Con todo ello, el Switch 4500G resulta idóneo para las pequeñas y medianas empresas que desean construir una red convergente segura.

Este switch dispone de una garantía limitada de por vida. También dispone de sustitución avanzada de hardware, con envío al siguiente día laborable en la mayoría de las regiones.

Power over Ethernet
Power over Ethernet (PoE) proporciona alimentación eléctrica y conectividad de datos sobre un mismo cable Ethernet, lo que redunda en unos ahorros de coste significativos a la hora de desplegar dispositivos tales como teléfonos IP, puntos de acceso inalámbricos, y cámaras de seguridad IP.

Seguridad avanzada
Las funcionalidades de seguridad de clase empresarial incluyen login de red IEEE 802.1X, login de dispositivo encriptado SSH/SSL, listas de control de acceso (ACLs) y RADA (acceso a dispositivos autenticados mediante RADIUS), protegiendo así las aplicaciones empresariales de misión crítica.

Conectividad de red preparada para voz
Minimiza el coste y la complejidad asociados con la instalación adicional o el traslado de teléfonos IP: el Switch 4500G detecta la presencia de teléfonos IP, y asigna dinámicamente puertos de switching a la VLAN de voz, permitiendo así una configuración y priorización automatizadas del tráfico de voz sobre IP (VoIP).
  Acceso y distribución avanzados para pequeñas y medianas empresas que desean construir una red convergente segura

48 puertos 10BASE-T/100BASE-TX/1000BASE-T con auto-negociación que soportan PoE en línea IEEE 802.3af; 4 de los cuales son Gigabit de uso dual 10/100/1000 o SFP

Desempeño a velocidad de cable sin bloqueo: capacidad agregada de switching de hasta 176 Gbps

Switching de Capa 2; el routing dinámico de Capa 3 incrementa el desempeño y mejora la seguridad de la red

Añada switches al cluster cuando sea necesario - sin incrementar la dificultad y el gasto de administración - y adminístrelos todos como una única entidad

Se pueden agrupar 32 dispositivos en cluster (Switch 4200G, 4500G y switches 5500 y 5500G)

El control de acceso de red IEEE 802.1X ofrece seguridad basada en estándares, combinada con autenticación RADIUS

El RADA (acceso a dispositivo autenticado mediante RADIUS) permite la autenticación de los dispositivos conectados mediante la dirección MAC, para un nivel adicional de seguridad de los puntos de entrada a la red

La asignación automática de tráfico VoIP a VLANs dedicadas ayuda a garantizar que el tráfico crítico sensible al tiempo consigue la prioridad necesaria para unas comunicaciones de calidad

Power over Ethernet proporciona alimentación eléctrica y conectividad de datos sobre un mismo cable Ethernet

2 ranuras traseras para módulos 10-Gigabit de 2 puertos, conexión local CX4 o basada en XFP
