Energy Efficient Design for Cost Savings
The Dell S4820T switch features an energy-efficient design, making it an ideal solution for organizations that are looking to reduce their energy costs while maintaining high-performance networking capabilities. The switch is designed to minimize power consumption while still providing organizations with the speed and performance they need to support their network applications.
One of the key features of the energy-efficient design of the S4820T switch is its support for Energy Efficient Ethernet (EEE) standards. EEE is a set of technologies that help to reduce power consumption by controlling the amount of energy used by the switch during periods of low network activity. This helps to significantly reduce the energy consumption of the switch, which in turn can lead to significant cost savings for organizations.
In addition, the S4820T switch is designed with an efficient cooling system that helps to minimize power consumption and reduce operating costs. The switch is also equipped with advanced power management features, such as automatic power control and the ability to power on and off specific ports, helping to further reduce energy consumption and operating costs.
Advanced Management and Monitoring Capabilities
The Dell S4820T switch features advanced management and monitoring capabilities, making it an ideal solution for organizations that require a high degree of control and visibility over their network infrastructure. The switch provides administrators with a range of tools and features that allow them to monitor and manage their network more effectively and efficiently.
One of the key management features of the S4820T switch is its web-based graphical user interface (GUI). This intuitive interface provides administrators with an easy-to-use and comprehensive set of tools for monitoring and managing the switch and its associated network devices. The GUI provides real-time information about switch performance, port statistics, and system events, allowing administrators to quickly identify and address any issues that may arise.
In addition, the S4820T switch supports Simple Network Management Protocol (SNMP), which allows administrators to manage and monitor the switch and its associated network devices from a remote location. This helps to streamline network management and reduce the need for manual intervention, resulting in improved network uptime and performance.
The switch also supports advanced features such as Link Aggregation Control Protocol (LACP) and Spanning Tree Protocol (STP), which help to ensure that the switch can be integrated into existing network infrastructure seamlessly and with minimal disruption. These features also help to improve network resiliency and availability, ensuring that critical network services are always available when they are needed.
Quality of Service (QoS) Support
Quality of Service (QoS) support is an important feature of the Dell S4820T switch that helps to ensure that critical network applications receive the bandwidth and resources they require for optimal performance. QoS helps to prioritize network traffic based on specific criteria, such as the type of application, source IP address, or destination IP address, to ensure that the most critical applications receive the bandwidth they need to operate effectively.
The S4820T switch supports a range of QoS features that allow administrators to prioritize network traffic based on their specific requirements. For example, administrators can prioritize traffic from high-priority applications, such as voice and video, to ensure that these applications receive the bandwidth they need for optimal performance. The switch also supports the ability to set different priority levels for different types of traffic, such as voice, video, and data, to ensure that the most critical applications receive the bandwidth they need.
In addition, the S4820T switch supports advanced QoS features, such as traffic shaping and congestion management, that help to ensure that network bandwidth is utilized efficiently. These features help to prevent network congestion and ensure that critical network applications receive the bandwidth they need, even during periods of high network activity.

About Refurbished Products
Different Types of Switches
Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).
Unmanaged Switches
The unmanaged switches offer fixed configurations on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.
Managed Switches
The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.
The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.
Smart Switches
Smart switches refer to switches that possess more features than those unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.
Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.
Modular Switches
Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
