Cisco SG300-28PP-K9-NA 28 Ports Managed Switch Ethernet Layer 3

Ports

The Cisco SG300-28PP-K9-NA Managed Switch is equipped with 28 ports, making it an ideal choice for small to medium-sized businesses that require a reliable and scalable network solution.

Increased Connectivity

With 28 ports, this managed switch offers ample connectivity options for connecting various devices such as computers, printers, servers, and IP cameras. The abundance of ports allows businesses to expand their network infrastructure without the need for additional switches or equipment.

Having multiple ports also enables businesses to create separate VLANs (Virtual Local Area Networks) to segregate traffic and improve network performance. For example, a company can assign different VLANs to departments like sales, marketing, and finance, ensuring that each department's traffic remains isolated and secure.

Power over Ethernet (PoE) Support

The Cisco SG300-28PP-K9-NA Managed Switch features Power over Ethernet (PoE) support on all 28 ports. This means that the switch can provide power to compatible devices like IP phones, wireless access points, and surveillance cameras directly through the Ethernet cable, eliminating the need for separate power sources.

This PoE capability simplifies the installation process and reduces cable clutter. It also allows businesses to deploy devices in locations where power outlets may not be easily accessible, such as ceilings or walls. With PoE support, businesses can enjoy greater flexibility in designing their network infrastructure.

Intelligent Power Allocation

The switch intelligently allocates power to connected devices based on their power requirements. It supports PoE+ (802.3at) standard, which provides up to 30 watts of power per port. This ensures that power-hungry devices like pan-tilt-zoom cameras or access points with multiple radios receive sufficient power for optimal performance.

Additionally, the switch features advanced power management capabilities, allowing businesses to prioritize power allocation to critical devices. This ensures that essential network components always have sufficient power, minimizing downtime and maintaining network reliability.

Cost Savings

By eliminating the need for separate power sources and reducing cable clutter, businesses can save on installation and maintenance costs. With PoE support, businesses can also avoid the hassle of running additional power cables to each device, reducing the overall infrastructure cost.

Moreover, the switch's intelligent power allocation helps optimize energy usage. By providing power only when required, businesses can significantly reduce their energy consumption and lower their electricity bills. This makes the Cisco SG300-28PP-K9-NA Managed Switch a cost-effective solution for organizations looking to enhance their network infrastructure.

Layer

The Cisco SG300-28PP-K9-NA Managed Switch operates at Layer 3 of the OSI (Open Systems Interconnection) model, offering advanced networking capabilities that are essential for modern business environments.

Enhanced Network Efficiency

Operating at Layer 3 allows the switch to perform routing functions, enabling efficient communication between different subnets or VLANs within a network. This capability improves network efficiency by reducing broadcast traffic and optimizing data flow.

In a Layer 3 network, the switch acts as a gateway, facilitating the routing of traffic between different IP subnets. This enables businesses to create logical networks and implement more granular security policies. For example, an organization can have separate VLANs for guest users and internal employees, ensuring that guest traffic is isolated from sensitive internal resources.

Scalability and Flexibility

Layer 3 switches offer greater scalability compared to Layer 2 switches. With Layer 3 capabilities, businesses can easily expand their network by adding new subnets or VLANs without compromising performance.

Additionally, Layer 3 switches support dynamic routing protocols such as OSPF (Open Shortest Path First) or EIGRP (Enhanced Interior Gateway Routing Protocol). These protocols allow the switch to exchange routing information with other routers, enabling dynamic and efficient routing decisions. This ensures that data takes the most optimal path through the network, enhancing overall network performance.

Improved Network Security

Layer 3 switches provide enhanced network security features compared to Layer 2 switches. By segmenting the network into multiple subnets or VLANs, businesses can implement access control policies based on IP addresses, improving network security.

Furthermore, Layer 3 switches offer features like Access Control Lists (ACLs) and traffic filtering, allowing businesses to control traffic flow and prevent unauthorized access to sensitive resources. These security measures help protect against potential threats and ensure that critical data remains secure.

In conclusion, the Cisco SG300-28PP-K9-NA Managed Switch's 28 ports provide increased connectivity options and Power over Ethernet support, simplifying installation and reducing costs. The Layer 3 capabilities enhance network efficiency, scalability, and security, making it an ideal choice for businesses seeking a reliable and advanced network solution.
