Detalles del producto

CISCO BUSINESS 250 SERIES ES LA PRóXIMA GENERACIóN DE CONMUTADORES INTELIGENTES ASEQUIBLES QUE COMBINAN UN POTENTE RENDIMIENTO Y FIABILIDAD DE LA RED CON UN CONJUNTO COMPLETO DE FUNCIONES DE RED QUE NECESITA PARA UNA RED EMPRESARIAL SóLIDA. ESTOS POTENTES CONMUTADORES GIGABIT ETHERNET, CON ENLACES ASCENDENTES GIGABIT O 10 GIGABIT ETHERNET, BRINDAN MúLTIPLES OPCIONES DE ADMINISTRACIóN, CAPACIDADES DE SEGURIDAD SOFISTICADAS Y CARACTERíSTICAS DE CALIDAD DE SERVICIO (QOS) AJUSTADAS Y ENRUTAMIENTO ESTáTICO DE CAPA 3 MUCHO MáS ALLá DE LAS DE UN CONMUTADOR NO ADMINISTRADO O DE NIVEL DE CONSUMIDOR. , A UN COSTO MENOR QUE PARA LOS CONMUTADORES TOTALMENTE ADMINISTRADOS. Y CON UNA INTERFAZ DE USUARIO WEB FáCIL DE USAR Y LA CAPACIDAD POWER OVER ETHERNET PLUS (POE +), PUEDE IMPLEMENTAR Y CONFIGURAR UNA RED EMPRESARIAL COMPLETA EN MINUTOS.
