Enhanced Performance and Reliability

The Dell S3148 switch is a managed 48-port rack-mountable switch designed for enhanced performance and reliability in data center, campus, and enterprise environments.

Performance: The switch is equipped with advanced features such as Quality of Service (QoS) and Link Aggregation Control Protocol (LACP) to prioritize and manage network traffic, ensuring that critical applications receive the bandwidth they need. The switch also supports high-speed data transfer rates of up to 1 Gbps on each port, providing fast and efficient data transmission.

Reliability: The switch features a redundant power supply, which provides increased uptime and reduces the risk of data loss in the event of a power failure. The switch also features robust security features such as Access Control Lists (ACLs) and port security, which help to prevent unauthorized access and protect against network attacks. Additionally, the switch supports industry-standard protocols such as IPv6, SNMP, and RMON, which provide enhanced network management and monitoring capabilities.

Power and Energy Efficiency

The 4WF3T Dell S3148 48 Ports Managed Rack-Mountable Switch is a high-performance network switch that is designed for both power efficiency and energy efficiency. This switch is equipped with advanced features and technologies that help to reduce the overall power consumption and increase the energy efficiency.

In terms of power efficiency, the 4WF3T Dell S3148 switch uses an advanced power management system that optimizes power usage according to the workload demands. The switch can be configured to enter power-saving mode when not in use, reducing the overall power consumption and saving energy. The switch also supports Energy Efficient Ethernet (EEE), which reduces power consumption during periods of low network activity.

In terms of energy efficiency, the 4WF3T Dell S3148 switch is designed with a high-performance, low-power architecture that reduces energy consumption. The switch supports the IEEE 802.3az Energy Efficient Ethernet standard, which optimizes power usage to reduce energy consumption during periods of low network activity. The switch also supports the IEEE 802.3af and 802.3at Power over Ethernet (PoE) standards, which allow power to be supplied to devices connected to the switch, reducing the need for separate power supplies.

Advanced Security Features

The 4WF3T Dell S3148 48 Ports Managed Rack-Mountable Switch offers advanced security features to ensure the safety and protection of your network. Some of the key security features include:

  • Access Control List (ACL): This feature allows you to define and control access to network resources by creating and applying rules for incoming and outgoing traffic.
  • 802.1X Authentication: The switch supports 802.1X authentication, which requires users to provide a unique username and password to access the network. This provides an extra layer of security to protect against unauthorized access.
  • Port Security: Port security allows you to limit the number of MAC addresses that can be associated with a specific port. This helps prevent unauthorized access to your network.
  • Dynamic ARP Inspection (DAI): DAI helps prevent ARP spoofing attacks by validating ARP packets and discarding any that are not legitimate.
  • Secure Shell (SSH): SSH provides encrypted remote access to the switch, ensuring that your login credentials and network information are protected.
  • RADIUS and TACACS+: The switch supports both RADIUS and TACACS+ authentication protocols, providing centralized authentication and authorization of network users.
  • Quality of Service (QoS): The switch supports QoS, allowing you to prioritize network traffic and ensure that critical applications receive the bandwidth they need.
  • Network Time Protocol (NTP): NTP helps keep the switch's clock synchronized with the rest of the network, ensuring that timestamps for network events are accurate.
