Cisco Media Gateway Controller Release 9 Regulatory Compliance and Safety Information

Translated Safety Warnings

Catalyst 5500 Power Supply Warning

Warning A design problem might affect a small percentage of Catalyst 5500 AC-input power supplies shipped as spares and AC-input power supplies shipped with chassis orders between December 1996 and December 1997. If you do not handle these power supplies with caution, you might experience a mild shock. We do not believe that the risk associated with this design problem is significant. We believe that the current design is safe when the power supply is handled correctly. Use the following procedure to safely remove AC-input power.

The power supply manufacturer, with technical assistance from Cisco, has implemented a design change to correct the problem. In addition, we will provide replacement AC-input power supplies to any customer upon request at no cost to the customer. To arrange for a replacement, contact Cisco Systems Customer Service at 800 553-NETS (6387), 408 526-7208, or e-mail cs-rep@cisco.com. If you need further technical assistance, contact the Technical Assistance Center (TAC) at 800 553-24HR (2447) or e-mail tac@cisco.com.

Waarschuwing Een probleem in het ontwerp kan een klein percentage van de invoerwisselstroomvoorzieningen van de Catalyst 5500 beïnvloeden die als reserveonderdelen werden verzonden en de invoerwisselstroomvoorzieningen die bij chassisbestellingen werden geleverd tussen december 1996 en december 1997. Als u deze stroomvoorzieningen niet voorzichtig hanteert, kunt u een lichte schok krijgen. Wij zijn van mening dat het risico dat verbonden is aan dit ontwerpprobleem niet beduidend is, maar dat het huidige ontwerp veilig is zolang de stroomvoorziening juist wordt gehanteerd. Gebruik de volgende procedure om de invoerwisselstroomvoorziening veilig te verwijderen.

De fabrikant van de stroomvoorziening heeft met behulp van technische assistentie van Cisco een ontwerpverandering geïmplementeerd om het probleem te corrigeren. Wij zullen bovendien op aanvraag onze klanten gratis voorzien van een vervangende invoerwisselstroomvoorziening. Neem contact op met de klantendienst van Cisco Systems op 800 553-NETS (6387), +1 408 526-7208 of per e-mail op cs-rep@cisco.com om een vervangende stroomvoorziening aan te vragen. Als u verdere assistentie nodig heeft, dient u contact op te nemen met het Technical Assistance Center (TAC) op 800 553-24HR (2447) of per e-mail op tac@cisco.com.

Varoitus Suunnitteluvirhe saattaa vaikuttaa joihinkin aikavälillä 12/1996 - 12/1997 varaosina toimitettuihin Catalyst 5500 -vaihtovirtalähteisiin sekä runkotilausten mukana toimitettuihin vaihtovirtalähteisiin. Jos kyseisiä virtalähteitä ei käsitellä varoen, seurauksena voi olla lievä sähköisku. Emme usko tämän suunnitteluvirheen aiheuttavan merkittävää riskiä. Uskomme nykyisen mallin olevan turvallinen, kun virtalähdettä käsitellään asianmukaisesti. Noudata seuraavaa menetelmää vaihtovirtalähteen irrottamiseksi turvallisesti.

Virtalähteen valmistaja on tehnyt Ciscon teknisellä avustuksella malliin muutoksia ongelman korjaamiseksi. Lisäksi toimitamme pyynnöstä uuden vaihtovirtalähteen sitä haluavalle asiakkaalle veloituksetta. Halutessasi vaihtaa virtalähteen ota yhteys Cisco Systemsin asiakaspalveluun soittamalla numeroon 1-800-553-6387 (Yhdysvaltain sisällä) tai +1-408-526-7208 tai lähettämällä sähköpostia osoitteeseen cs-rep@cisco.com. Jos tarvitset lisää teknistä tukea, ota yhteys teknisen tuen keskukseen (Technical Assistance Center,TAC) soittamalla numeroon 1-800-553-2447 (Yhdysvaltain sisällä) tai lähettämällä sähköpostia osoitteeseen 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.
