Cisco SG500-52-K9 52 Ports Ethernet Switch Layer 2 Refurbished

• Fast and Gigabit Ethernet Support: The SG500-52-K9 supports both Fast Ethernet (10/100 Mbps) and Gigabit Ethernet (10/100/1000 Mbps) speeds. This dual-speed capability is beneficial for businesses with a mix of older and newer network devices. It ensures backward compatibility while also providing the bandwidth necessary for modern, high-performance applications.
• High-Speed Data Transfer: With Gigabit Ethernet support, the switch facilitates high-speed data transfer, reducing latency and ensuring faster response times for connected devices. This is particularly advantageous in environments where data-intensive applications, such as video streaming or large file transfers, are commonplace. The switch's ability to handle large volumes of data traffic contributes to an efficient and responsive network.
• Scalability for Growing Networks: The SG500-52-K9 is designed with scalability in mind. The abundance of Ethernet ports and SFP ports allows businesses to easily expand their network infrastructure as the need arises. This scalability is crucial for growing enterprises that anticipate an increase in the number of connected devices and a higher demand for network resources over time.

The inclusion of Twisted Pair Fast Ethernet in the SG500-52-K9 ensures reliable and high-speed data transfer within the network. Fast Ethernet, with a data rate of 100 Mbps, is well-suited for tasks such as basic file sharing, email communication, and internet browsing.

For bandwidth-intensive applications and larger data transfers, the Gigabit Ethernet capability of the switch becomes indispensable. With a data rate of 1000 Mbps, Gigabit Ethernet significantly enhances network performance, supporting activities like video conferencing, large file transfers, and multimedia streaming seamlessly.

• Versatility: Supporting both Fast Ethernet and Gigabit Ethernet, the switch accommodates a variety of devices with different speed requirements. This versatility is crucial for businesses with a diverse range of networked devices, ensuring seamless integration without the need for additional equipment.
• Reliability: The inclusion of Combo Gigabit SFP ports enhances the reliability of the network by allowing the use of fiber-optic connections. Fiber optics offer advantages such as higher data transfer speeds, immunity to electromagnetic interference, and longer reach, making the network more robust and resilient.
• Efficient Space Utilization: The 1U rack-mountable design is a space-saving feature that is especially beneficial for small business environments with limited rack space. The switch's compact form factor doesn't compromise performance, making it an efficient solution for optimizing space in network cabinets.
• Advanced Layer 2 Features: The Layer 2 management capabilities of the SG500-52-K9 contribute to network efficiency and stability. Features such as VLAN support enable the segmentation of networks for improved traffic management, while Spanning Tree Protocol enhances the resilience of the network by preventing loops.

The Cisco SG500-52-K9 is designed to be a high-reliability switch for small businesses. Some of the features that contribute to its reliability include:

• Redundant power supplies: The switch has two power supplies, which provide redundancy in case one power supply fails.
• Stackable design: The switch can be stacked with other SG500 switches, which allows for redundancy in case one switch fails.
• Quality of Service (QoS): The switch supports QoS, which allows for prioritization of certain types of traffic, such as voice or video, to ensure that critical applications have the bandwidth they need.
• VLANs: The switch supports VLANs, which can be used to segment the network and improve security.
• Advanced security features: The switch supports advanced security features such as 802.1x authentication, access control lists, and DHCP snooping to help protect against network threats.
• Web-based management interface: The switch has a web-based management interface, which allows for easy configuration and monitoring of the switch, and allows for remote management.

All of these features work together to provide a high-reliability network for small businesses, which can help to ensure that mission-critical applications are always available and that network downtime is minimized.
