The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

•Turn the television or radio antenna until the interference stops.

•Move the equipment to one side or the other of the television or radio.

•Move the equipment farther away from the television or radio.

•Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

3550 specifications

Cisco Systems 3550 is a series of enterprise-class multilayer switches that have gained popularity in both enterprise and service provider networks. Introduced in the early 2000s, the 3550 series was designed to meet the increasing demand for advanced networking capabilities, including Layer 2 and Layer 3 switching, making it suitable for various network environments.

A standout feature of the Cisco 3550 is its support for advanced Layer 3 switching capabilities. This means it can perform routing functions similar to traditional routers while maintaining the speed and efficiency of a switch. The 3550 facilitates IP routing, enabling enhanced communication among different subnets without the need for additional routing devices.

The Cisco 3550 series is equipped with a range of ports, typically providing up to 48 Ethernet 10/100 ports and optional Gigabit Ethernet ports, ensuring scalability and flexibility in various network designs. The switches support Power over Ethernet (PoE), allowing the delivery of electrical power through Ethernet cables to connected devices, such as IP phones and wireless access points, streamlining installations and reducing cable management complexity.

Quality of Service (QoS) is another essential feature of the Cisco 3550. The switch supports advanced QoS mechanisms, which provide the ability to prioritize traffic. This is crucial in environments where bandwidth is limited, as it ensures that time-sensitive applications, like VoIP and video conferencing, receive sufficient bandwidth to function optimally.

In terms of security, the Cisco 3550 includes features such as access control lists (ACLs), port security, and VLANs (Virtual Local Area Networks). These features help in segmenting network traffic and preventing unauthorized access to sensitive information, thereby enhancing network security.

The Cisco 3550 is highly regarded for its robustness and reliability, making it a suitable choice for various organizations looking to maintain high availability in their networking environments. Its management capabilities include support for Cisco's IOS software, which offers a command-line interface for configuration, as well as options for SNMP and web-based management tools.

Overall, the Cisco Systems 3550 series is well-regarded for its multilayer switching capabilities, comprehensive feature set, and versatility in meeting the diverse needs of modern networking, making it a favored solution for businesses aiming to build efficient and secure network infrastructures.
