The Cisco SG350-28-K9-NA is a Layer 3 Managed Switch that provides 28 ports, making it suitable for small to medium-sized businesses. It belongs to Cisco's Small Business Switch portfolio, known for delivering enterprise-level performance in a compact and cost-effective package. Let's break down the key aspects of this switch:

The switch comes equipped with 28 ports, offering flexibility in connecting various devices, such as computers, printers, IP cameras, and other networking peripherals. Understanding the port configuration is crucial for optimizing network architecture.

One standout feature of the Cisco SG350-28-K9-NA is its Layer 3 management capabilities. Unlike Layer 2 switches, Layer 3 switches operate at the network layer, enabling them to route data between different subnets. This functionality enhances network efficiency and performance.

The switch supports Gigabit Ethernet, providing high-speed data transfer within the local network. This is essential for applications that demand low latency and large bandwidth, such as video conferencing and data-intensive tasks.

Cisco's QoS implementation on the SG350-28-K9-NA ensures that critical applications receive priority in terms of bandwidth allocation. This is particularly beneficial in environments where different types of traffic coexist, preventing congestion and optimizing performance.

Security is a paramount concern in modern networks. The switch incorporates robust security features, including VLAN support, Access Control Lists (ACLs), and MAC-based port security. These measures help safeguard the network from unauthorized access and potential threats.

In response to the evolving landscape of the internet, the Cisco SG350-28-K9-NA is designed to support IPv6, the latest version of the Internet Protocol. This ensures future-proofing and compatibility with the latest networking technologies.

The switch's 28 ports and Layer 3 capabilities make it highly scalable, allowing businesses to expand their network infrastructure as needed. This scalability is essential for accommodating the growth of devices and data within an organization.

The switch is designed with reliability in mind, featuring redundant power options and Quality of Service mechanisms that ensure uninterrupted service delivery. Redundancy is a critical aspect of network design, reducing the risk of downtime and data loss.

The Cisco SG350-28-K9-NA boasts a substantial switching capacity, allowing for efficient data handling and routing. This is a key parameter for assessing the overall performance of the switch in diverse networking scenarios.

Power over Ethernet simplifies the deployment of network devices by delivering both data and electrical power over a single Ethernet cable. The switch's PoE support is beneficial for powering devices like IP cameras, VoIP phones, and wireless access points.

The fanless design of the SG350-28-K9-NA contributes to silent operation, making it suitable for deployment in noise-sensitive environments. This feature is particularly advantageous in small office settings or locations where minimal noise is preferred.

Small to Medium-sized Businesses

The Cisco SG350-28-K9-NA is tailored for the networking needs of small to medium-sized businesses. Its scalability, reliability, and ease of management make it an ideal choice for organizations looking to establish or upgrade their network infrastructure.

IP Surveillance Networks

With PoE support and Layer 3 capabilities, the switch is well-suited for IP surveillance networks. It can efficiently handle the data traffic from multiple IP cameras while providing the necessary routing for secure and segregated surveillance subnets.

Educational Institutions

In educational settings, where a diverse range of devices needs to be connected securely, the Cisco SG350-28-K9-NA offers the required features. Its robust security measures and scalability make it suitable for creating a reliable and efficient network in schools and universities.
