Dell S5148F Networking Switch is a high-performance network switch designed for large data centers, cloud providers, and other high-bandwidth environments. It has 48 ports of 25GbE SFP28 and six ports of 100GbE QSFP28, making it ideal for connecting servers, storage devices, and other networking equipment.

Port Configuration

The Dell S5148F switch has 48 ports of 25GbE SFP28, which means that it can support up to 48 devices at a maximum speed of 25 gigabits per second. The SFP28 ports are compatible with both copper and fiber optic cables, allowing for flexible connectivity options.

In addition to the 25GbE SFP28 ports, the Dell S5148F switch has six ports of 100GbE QSFP28. These ports can support up to six devices at a maximum speed of 100 gigabits per second. The QSFP28 ports can be used with either copper or fiber optic cables, making them ideal for high-speed connections between switches or routers.

Switching Capacity

The Dell S5148F switch has a high switching capacity of up to 2.16 terabits per second (Tbps). This means that it can handle a large amount of data traffic without experiencing any performance issues. The switch also has a forwarding rate of up to 1.6 billion packets per second (Bpps), making it an ideal choice for data centers and other high-bandwidth environments.


The Dell S5148F switch has a low latency of 500 nanoseconds (ns). This means that it can process and forward data packets quickly, without any delay or lag. Low latency is essential for high-performance applications, such as online gaming, video streaming, and real-time data analytics.

Power Efficiency

The Dell S5148F switch is designed to be power-efficient, with a maximum power consumption of only 580 watts. This makes it an environmentally friendly option for data centers and other facilities that are concerned about their carbon footprint.


The Dell S5148F switch can be managed using a variety of methods, including a web-based graphical user interface (GUI), a command-line interface (CLI), and Simple Network Management Protocol (SNMP). The switch also supports Dell EMC OpenManage Network Manager, which provides comprehensive network management capabilities, including configuration, monitoring, and troubleshooting.


The Dell S5148F switch has a range of security features to protect against unauthorized access and data breaches. It supports multiple authentication methods, including RADIUS, TACACS+, and LDAP. The switch also has access control lists (ACLs) and port security features to prevent unauthorized access to network resources.

Quality of Service

The Dell S5148F switch has a range of Quality of Service (QoS) features to prioritize network traffic and ensure that critical applications receive the necessary bandwidth. It supports eight hardware queues per port and has a range of QoS policies, including weighted fair queuing (WFQ), strict priority (SP), and hybrid queuing.

In Summary, The Dell S5148F Networking Switch is a high-performance switch designed for large data centers and other high-bandwidth environments. It has 48 ports of 25GbE SFP28 and six ports of 100GbE QSFP28, making it ideal for connecting servers, storage devices, and other networking equipment. The switch has a high switching capacity of up to 2.16 Tbps and a low latency of 500 ns, making it an ideal choice for high-performance applications.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

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.
