Translated Safety Warnings

¡Advertencia! Un problema de diseño puede afectar un pequeño porcentaje de los suministros de energía de entrada CA (corriente alterna) del Catalyst 5500 que fueron enviados como repuestos y los suministros de energía CA que se mandaron junto los pedidos de chasis entre los meses de diciembre 1996 y diciembre 1997. Si Ud. no trata estos suministros de energía con cuidado puede experimentar un choque moderado. No creemos que el riesgo asociado con este problema de diseño sea significante. Creemos que el diseño actual es seguro cuando el suministro de energía se usa de manera correcta. Utilice el siguiente procedimiento para retirar la entrada de energía de corriente alterna -CA.

El fabricante de suministro de energía asistido por técnicos de Cisco, ha implementado un cambio en el diseño para corregir el problema. Además, proporcionaremos repuestos de suministro de energía de corriente alterna -CA sin recargo para el cliente que así lo desee. Para obtener un repuesto póngase en contacto con el departamento de Servicio al Cliente de Cisco Systems, Inc. al

800533-NETS (6387), 408 526 -7208, o bien por correo electrónico cs-rep@cisco.com. Si necesita ayuda técnica adicional póngase en contacto con el Centro de Asistencia Técnica (TAC) al número

Varning! Ett designfel påverkar eventuellt ett litet antal växelströmsaggregat av modell Catalyst 5500 som levererades som reservdelar samt tillsammans med chassier mellan december 1996 och december 1997. Dessa aggregat måste hanteras med försiktighet, annars kan man få en lätt stöt. Enligt vår uppfattning medför detta designfel inga betydande risker. Vi anser att nuvarande design är säker så länge aggregatet hanteras på rätt sätt. Avlägsna växelströmsaggregatet på ett säkert sätt enligt följande.

Med hjälp av teknisk assistans från Cisco har aggregatets tillverkare utfört en designändring för att åtgärda felet. Dessutom erbjuder vi på begäran nytt växelströmsaggregat kostnadsfritt till alla våra kunder. Beställ nytt aggregat genom att kontakta Cisco Systems kundtjänst på 800 553-NETS (6387), 408 526-7208, eller skicka e-mail: cs-rep@cisco.com. Om vidare teknisk assistans krävs ber

vikunden att kontakta Technical Assistance Center (TAC) [center för teknisk assistans] på 800 553-24HR (2447), eller skicka e-mail: tac@cisco.com.

Gateway Controllers specifications

Cisco Systems Gateway Controllers play a pivotal role in the modern networking landscape, particularly within service provider infrastructures. These devices serve as critical components that facilitate the efficient management of voice, video, and data traffic, enabling seamless communication across diverse networks. Combining robustness, scalability, and advanced features, Cisco's Gateway Controllers provide businesses with the tools necessary to optimize their network environments.

One of the standout features of Cisco Gateway Controllers is their ability to handle various signaling protocols, including SIP (Session Initiation Protocol), H.323, and MGCP (Media Gateway Control Protocol). This flexibility ensures interoperability with a wide range of telecom systems and devices, which is crucial for organizations transitioning to IP-based communications.

Integration of voice and video services is made seamless through advanced transcoding capabilities. Cisco Gateway Controllers can convert media streams between different codecs, ensuring high-quality communication regardless of the endpoint's capabilities. This is particularly valuable for enterprises with a mix of legacy and modern communications equipment, as it protects existing investments while facilitating growth.

Traffic management is another significant characteristic of Cisco Gateway Controllers. They utilize sophisticated traffic engineering techniques to prioritize real-time communication signals and optimize bandwidth allocation. Quality of Service (QoS) mechanisms ensure that voice and video traffic is given priority over data traffic, reducing latency and maintaining call quality even during peak usage.

Security features are also a hallmark of Cisco's solutions. Gateway Controllers include robust encryption, access control, and intrusion prevention systems to ensure that network communications are protected against potential threats. This is increasingly important as organizations face a growing number of cybersecurity challenges.

Additionally, Cisco's extensive software ecosystem, including platforms like Cisco Unified Communications Manager, allows for an integrated approach to communication solutions. This interconnectivity not only simplifies management but also enhances the capabilities of Cisco's Gateway Controllers by enabling advanced features like unified messaging and presence information.

Overall, Cisco Systems Gateway Controllers combine advanced technologies, essential features, and security measures to support modern networking needs. Their ability to handle diverse communication protocols, coupled with traffic management and high-level integration, positions them as a crucial solution for organizations seeking to leverage the full potential of converged communication systems. By incorporating these services, businesses can enhance operational efficiency and improve overall user experience, paving the way for future technological advancements in communication.
