    24 Port L2 Managed Fast Ethernet Switch 10/100BASE + 4 Gigabit-Uplink Ports + 2 SFP Transceiver Ports

    What This Product Does

    Designed for workgroups and departments, NPNB-TL-SL5428E from Fiber Savvy provides full set of layer 2 management features. It delivers maximum throughput where you need it — to high-performance workgroups at the edge of the network, or as a backbone for Fast Ethernet switches and high-speed servers in demanding small networks. Moreover, NPNB-TL-SL5428E switch also comes equipped with 2 combo SFP slots, giving you greater network flexibility.

    This Fiber Savvy L2 managed switch has robust security and management features. An advanced Access Control List (ACL,L2 to L4) and the Fiber Savvy strong safeguard provide security coverage from core to edge and protect against broadcast storm, ARP and Denial-of-Service (DoS) attacks, etc. Quality of Service (QoS, L2 to L4) provides enhanced traffic management capabilities to move your data smoother and faster. Anymore, the easy-to-use web management interfaces, along with CLI, SNMP and RMON, mean faster setup and configuration with less downtime.

    Non-Blocking Switching

    The Fiber Savvy fully managed L2 switch NPNB-TL-SL5428E provides non-blocking switching solution for a 10/100 fast Ethernet connection. As to the switching capacity, NPNB-TL-SL5428E has a non-blocking aggregated bandwidth of 12.8Gbps. It provides 24 10/100Mbps ports and 4 gigabit 10/100/1000BASE-T ports. In these gigabit copper ports, two of these ports are combo gigabit ports, which will be disabled if the corresponding 1000BASE-X SFP slots are used. It can give you greater network flexibility.

    Virtual Stackable

    IP Clustering allows up to 32 NPNB-TL-SL5428E switches to be managed by a single IP, regardless of geographical locations. With all units identified by a single IP address, the stack could be configured, monitored, maintained as a single object.

    Traffic running across units in this virtual stack utilizes full-duplex interfaces and network wires, eliminating costly and cumbersome cables, minimizing the impact of any single point of failure.

    Comprehensive Security Strategy

    Access Control Lists (ACL, L2 to L4) restrict access to sensitive network resources by denying packets based on source and destination MAC address, IP address, TCP/UDP ports and even VLAN ID. This is done by hardware, so switching performance would not be compromised.

    Moreover, the NPNB-TL-SL5428E switch supports 802.1X authentication, which is used in conjunction with a RADIUS server to require some authentication information before access to the network is allowed. And more, it supports Guest VLAN to enable the non-802.1X clients to access the specific network resource. In addition,IP-MAC-Port-VID Binding, Port Security, Storm control, DHCP Snooping and IP Source Guard support can protect against broadcast storms, ARP and Denial-of-Service (DoS) attacks, etc. Regarding to the DoS defending, NPNB-TL-SL5428E provides you some typical DoS attacks to select. You can protect these attacks more easily ever than before. NPNB-TL-SL5428E will provide you robust security to the network.

    Enterprise Level Manageability and Resiliency

    NPNB-TL-SL5428E supports various user-friendly standard management features,such as intuitive web-based Graphical User Interface(GUI)or industry-standard Command Line Interface (CLI), either administration traffic can be protected through SSL or SSH encryptions. SNMP (v1/2/3) and RMON support enables the switch to be polled for valuable status information and send traps on abnormal events. This sharing of vital management information saves time and money. With link aggregation, spanning tree protocol (STP/RSTP/MSTP) and virtual stack, a highly intelligent and scalable topology could be established, fulfilling the enterprise customers´ requirement of building a unified, resilient network.

    Optimized Voice and Video Applications

    To integrate voice, data and video service on one network, NPNB-TL-SL5428E applies rich QoS policies. Administrator can designate the priority of the traffic based on a variety of means including IP or MAC address, TCP or UDP port number, etc, so voice and video are always clear, smooth and jitter free. In conjunction with the Voice VLAN the switch supporting, the voice applications will operate with much smoother performance.

    For other multimedia-on-demand application such as IPTV, NPNB-TL-SL5428E provides advanced features for easy stream management. For example, IGMP snooping ensures the switch intelligently forward the multicast stream only to the appropriate subscribers while IGMP throttling & filtering restrict each subscriber on a port level to prevent unauthorized multicast access.

    Additional Information

    Ethernet Switch Accessories

    An Ethernet network switch is a telecommunication device that receives data transmitted from a connected device and relays it to a specific device. Ethernet switches create separate collision domains per switch port, allowing for simultaneous data transfers to occur without interference. They also reduce the number of broadcast domains, and don’t require heavy CPU usage. Learn More
