Product overview of Dell S4820T Networking 48 Ports
The Dell S4820T Networking Switch is a high-performance switch that is designed for data center networks. It is a Layer 2 and Layer 3 switch that comes with 48 ports of 10 Gigabit Ethernet (GbE) and four ports of Quad Small Form-factor Pluggable (QSFP) that enable high-speed connectivity. The switch features hot-swappable power supplies, fans, and modules, making it highly reliable and easy to maintain.
Overview
The Dell S4820T Networking Switch is a high-performance switch that is designed to provide high-speed connectivity for data center networks. The switch has 48 ports of 10 GbE, which enables high-speed data transfer between devices. The switch also has four ports of QSFP, which support 40 GbE and enable high-speed connectivity between switches.
The switch supports Layer 2 and Layer 3 networking protocols, which means that it can be used to create both simple and complex network topologies. It also supports a range of advanced features such as Quality of Service (QoS), Link Aggregation Control Protocol (LACP), and Virtual Router Redundancy Protocol (VRRP), which help to improve network performance and reliability.
48 Ports of 10 GbE
The Dell S4820T Networking Switch comes with 48 ports of 10 GbE, which enables high-speed data transfer between devices. This is particularly useful for data centers where large amounts of data need to be transferred quickly. The 10 GbE ports are also backwards compatible with 1 GbE, which means that devices that do not support 10 GbE can still connect to the switch.
4 Ports of QSFP
The switch also has four ports of QSFP, which support 40 GbE and enable high-speed connectivity between switches. This is useful for creating high-speed network topologies where switches need to be connected together to provide additional bandwidth. The QSFP ports can also be used for stacking switches together to create a single logical switch.
Power Supplies, Fans, and Modules
The Dell S4820T Networking Switch features hot-swappable power supplies, fans, and modules. This means that if a power supply, fan, or module fails, it can be replaced without having to turn off the switch. This makes the switch highly reliable and easy to maintain.
Layer 2 and Layer 3 Networking Protocols
The switch supports Layer 2 and Layer 3 networking protocols. This means that it can be used to create both simple and complex network topologies. Layer 2 protocols are used to provide network connectivity between devices on the same network, while Layer 3 protocols are used to provide connectivity between devices on different networks.
Quality of Service (QoS)
The switch supports Quality of Service (QoS), which is a set of techniques used to manage network traffic and ensure that critical traffic is given priority over non-critical traffic. This helps to ensure that network performance is optimized and that critical applications are not affected by non-critical traffic.
Link Aggregation Control Protocol (LACP)
The switch also supports Link Aggregation Control Protocol (LACP), which is used to combine multiple physical links into a single logical link. This helps to increase bandwidth and improve network performance. LACP is particularly useful for connecting switches together to provide additional bandwidth.
Virtual Router Redundancy Protocol (VRRP)
The switch also supports Virtual Router Redundancy Protocol (VRRP), which is used to provide redundancy for routers. VRRP enables multiple routers to work together to provide a single virtual router, which helps to ensure that network traffic is always routed correctly, even if one of the routers fails.

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.

Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
