High-Speed Data Transfer of 48 Ports Switch

The Dell Networking S4148F-ON switch is a high-speed data transfer switch designed for use in data centers and other network environments that require high-performance networking. It supports 48 ports of 10 GBE SFP++ and 2x QSFP+ and 4x QSFP28 for connecting to other networking devices.

The 10 GBE SFP++ ports provide fast data transfer speeds of up to 10 gigabits per second, making it ideal for applications that require high bandwidth. The 2x QSFP+ and 4x QSFP28 ports provide even higher bandwidth and can be used for 40 gigabit or 100 gigabit connectivity. This makes the switch suitable for use in high-density networking environments, such as data centers, where large amounts of data need to be transferred quickly and efficiently.

The Dell Networking S4148F-ON switch supports Open Network Install Environment (ONIE) for zero-touch installation and supports multiple network operating systems, including Dell Networking OS, Cumulus Linux, and SONiC. It also supports advanced network features such as Quality of Service (QoS), Virtual LANs (VLANs), and Link Aggregation Control Protocol (LACP).

In conclusion, the Dell Networking S4148F-ON switch provides a high-speed, high-performance solution for data centers and other network environments that require fast data transfer and advanced network features.

Powerful Connectivity Solutions

The Dell 247PW Networking S4148F-ON 48 Ports 10 GBE SFP++ 2x QSFP+ 4x QSFP28 Switch is a high-performance networking solution designed for businesses and organizations that require fast and efficient connectivity. The switch features 48 ports of 10 GBE SFP++ and 2x QSFP+ 4x QSFP28, providing a wide range of connectivity options to meet the needs of any network infrastructure.

The 10 GBE SFP++ ports allow for fast data transfer and efficient communication between devices, while the 2x QSFP+ and 4x QSFP28 ports provide high-density connections for fiber and copper cabling, making it easy to connect devices over long distances. This switch also supports Open Network Install Environment (ONIE) for easy installation and management of network devices, making it easy to configure and manage the switch without the need for specialized knowledge.

In addition, the S4148F-ON switch supports software-defined networking (SDN) protocols, allowing for flexible and dynamic network configuration, making it easy to adapt to changing network requirements. The switch also features advanced security features, including IEEE 802.1X port-based access control and Quality of Service (QoS) capabilities, ensuring secure and reliable connectivity for all connected devices.

Robust Security Features

The Dell 247PW Networking S4148F-ON switch is equipped with several robust security features to protect your network from cyber threats and unauthorized access. These features include:

  • Access Control Lists (ACLs) - This feature allows you to restrict access to specific network segments based on IP addresses, ports, and other network parameters.
  • 802.1X Port-Based Authentication - This feature provides secure authentication of network devices and users, ensuring that only authorized devices and users have access to the network.
  • SSH/SSL Encryption - Secure Shell (SSH) and Secure Sockets Layer (SSL) encryption technologies protect sensitive data as it travels over the network, preventing eavesdropping and tampering.
  • RADIUS/TACACS+ Authentication - Remote Authentication Dial-In User Service (RADIUS) and Terminal Access Controller Access Control System Plus (TACACS+) are used to secure network access by verifying the identities of users and devices before allowing them to connect to the network.
  • DHCP Snooping - Dynamic Host Configuration Protocol (DHCP) snooping is used to prevent unauthorized DHCP servers from assigning IP addresses to devices on the network.
  • Dynamic ARP Inspection (DAI) - ARP (Address Resolution Protocol) is used to map IP addresses to physical addresses. DAI inspects ARP packets and verifies that they are legitimate, preventing ARP spoofing attacks.
  • IP Source Guard - IP Source Guard prevents unauthorized devices from accessing the network by verifying the IP addresses of devices trying to connect to the network.
  • Port Security - Port security allows you to restrict the number of devices that can be connected to a specific port on the switch, preventing unauthorized devices from accessing the network.

These robust security features ensure that your network is protected from cyber threats and unauthorized access, providing peace of mind for your organization.

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.
