Advanced Routing Capabilities

The Dell EMC S4148U-ON switch is a managed Layer 3 switch that provides advanced routing capabilities. Here are some of the key features:

  • Routing Protocols: The switch supports both static and dynamic routing protocols such as OSPF, BGP, and IS-IS, which help to efficiently manage the flow of data in large networks.
  • VLANs: The switch supports the creation of multiple virtual local area networks (VLANs) within a single physical network, allowing for better network segmentation and security.
  • Quality of Service (QoS): The switch supports advanced QoS features, including traffic prioritization and bandwidth management, to ensure that critical applications receive the necessary bandwidth and low latency.
  • Link Aggregation: The switch supports link aggregation, allowing multiple physical connections to be grouped together to form a single logical connection. This helps to increase bandwidth and reliability.
  • IPv6 Support: The switch supports IPv6, the latest version of the Internet Protocol, which provides expanded addressing capabilities and improved security compared to IPv4.
  • Access Control Lists (ACLs): The switch supports ACLs, which can be used to control access to network resources based on specified criteria, such as source IP address, destination IP address, or protocol.
  • Stackable Design: The switch is stackable, meaning multiple switches can be combined to form a single, highly scalable network.

In conclusion, the Dell EMC S4148U-ON switch provides a range of advanced routing capabilities, including support for routing protocols, VLANs, QoS, link aggregation, IPv6, and ACLs, making it a powerful solution for organizations looking to build scalable, secure, and high-performing networks.

Scalable and Reliable

The Dell 4XKT9 EMC 48 Ports Networking S4148U-ON Managed L3 Switch is a highly scalable and reliable network switch that is designed to meet the demands of modern data centers. With 48 ports of 10/25 GbE and support for both LAN and data center bridging (DCB), this switch can accommodate a wide range of networking needs.

The switch is built for scalability and reliability with advanced features such as redundant power supplies, hot-swappable fans, and a modular design that enables easy upgrades and maintenance. The S4148U-ON also supports stacking, allowing multiple switches to be combined into a single logical switch, providing increased bandwidth and ease of management.

Additionally, the switch is managed through the Open Network Install Environment (ONIE), which enables easy deployment of network operating systems such as Dell EMC Networking OS10. This enables administrators to manage the switch from a central location, reducing downtime and increasing network efficiency.

With L3 support, the S4148U-ON can also perform routing, making it a great choice for data center and enterprise networks. With its robust hardware and advanced features, the Dell 4XKT9 EMC 48 Ports Networking S4148U-ON Managed L3 Switch is a scalable and reliable solution for modern networking needs.

Energy Efficiency and Power Management

The Dell 4XKT9 EMC 48 Ports Networking S4148U-ON Managed L3 Switch is designed with energy efficiency and power management in mind.

  • Energy Efficiency: The switch uses less power, which saves energy and reduces operating costs. It also has Energy Efficient Ethernet (EEE) technology, which reduces power consumption during periods of low network traffic.
  • Power Management: The switch features a power supply with an internal power supply redundancy, which provides a secondary power source to keep the network running if the primary power supply fails. The switch also has a management interface that enables administrators to monitor power usage and adjust power settings to meet their specific needs.
  • Power Over Ethernet (PoE): The switch supports PoE, which allows power to be delivered over Ethernet cables to power devices such as access points, cameras, and phones. This eliminates the need for separate power sources, reducing energy costs and clutter.
  • Energy Efficient Link Aggregation: The switch supports Energy Efficient Link Aggregation (EELA), which balances the distribution of traffic across multiple links, reducing power consumption and improving overall energy efficiency.
