Cisco SG250-26-K9-NA 26 Ports Ethernet Switch Refurbished

The Cisco SG250-26-K9-NA is a type of network switch designed for small businesses. It's part of the SG250 series offered by Cisco, specifically catering to the needs of businesses that require efficient networking solutions without the complexity of larger enterprise-grade setups.

An Ethernet switch, like the Cisco SG250-26-K9-NA, serves as a central hub for connecting devices within a network. It allows multiple devices, such as computers, printers, and servers, to communicate with each other by transmitting data across the network.

This particular switch comes with a total of 26 ports. Among these, there are 24 Ethernet ports, allowing direct connections for devices like computers or network-enabled printers. Additionally, there are 2 Combo Gigabit Small Form-Factor Pluggable (SFP) ports. These SFP ports offer flexibility in connecting to other networking equipment using fiber optic or copper cables.

The Cisco SG250-26-K9-NA is a managed switch, meaning it offers advanced functionalities for network administrators to monitor and control the network. This includes features like Quality of Service (QoS) settings, VLAN (Virtual LAN) support for segmenting the network, and security protocols for protecting data.

With support for Gigabit Ethernet, this switch allows for high-speed data transmission within the network. It ensures that data moves swiftly between connected devices, enhancing overall network performance.

For growing businesses, this switch provides scalability. With its multiple ports and managed capabilities, it can easily accommodate additional devices as the business expands.

Despite being a managed switch, the Cisco SG250-26-K9-NA offers a user-friendly interface for configuration and management. Small business owners or IT administrators can easily set it up without extensive technical expertise.

Security features such as access control lists (ACLs) and encryption protocols help safeguard sensitive data transmitted over the network. This is crucial for protecting business information and ensuring confidentiality.

Use Cases and Applications

The Cisco SG250-26-K9-NA switch can be employed in various scenarios within small business environments. It's suitable for office networks, retail establishments, small-scale manufacturing setups, and other similar environments where a reliable and manageable network infrastructure is needed.

The SG250-26-K9-NA is a managed switch from the Cisco Small Business 250 series that provides advanced features for small business networks. Some of these features include:

• 26 Gigabit Ethernet ports: Provides fast and reliable network connections for devices.
• Security: Supports access control lists (ACLs) and 802.1X authentication to secure network access and prevent unauthorized access.
• Virtual LAN (VLAN) support: Allows network segmentation to improve network security and organization.
• Quality of Service (QoS): Prioritizes network traffic to ensure critical applications receive sufficient bandwidth.
• Bandwidth control: Helps to improve network utilization by defining bandwidth limits for individual ports or traffic types.
• Monitoring and reporting: Provides real-time network monitoring and reporting to help administrators quickly identify and resolve network issues.
• Link Aggregation (LAG) support: Load balances network traffic and provides redundancy for increased network reliability.
• Dynamic routing: Supports Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) for dynamic routing.
• Management options: Provides easy-to-use web-based, CLI, and SNMP management options for administrators.

These advanced features provide small businesses with the tools needed to improve network efficiency, security, and reliability, enabling them to achieve their business objectives.

The SG250-26-K9-NA provides reliable network performance through the following features:

• Quality of Service (QoS): The switch supports QoS, which allows administrators to prioritize network traffic based on the type of data being transmitted. This can help ensure that critical applications receive the bandwidth they need, even during periods of heavy network traffic.
• Link Aggregation: The switch supports Link Aggregation Control Protocol (LACP) for increased availability of network connections. This allows administrators to bundle multiple physical links into a single logical link, providing increased bandwidth and redundancy.
• Spanning Tree Protocol: The switch supports Spanning Tree Protocol (STP), which helps prevent loops and ensures a single active path between switches. This can help prevent network outages and improve network reliability.
• VLAN Support: The switch supports Virtual LANs (VLANs), which can help improve network security and performance by separating traffic into different virtual networks.
• Easy Management: The switch is easy to manage and provides a web-based GUI for configuration and management. The switch also supports Simple Network Management Protocol (SNMP) for remote monitoring and management.
