28 Port Gigabit Managed Switch with 4 SFP Fiber Ports (SR-SG3428FC)

Gigabit 28 Port Managed Switch with 4 SFP Fiber Ports(SR–SG3428FC)   Product Description Advanced 28-Port Layer 2 Managed Switch with Fiber Connectivity SR-SG3428FC is a layer 2 managed switch equipped with 24 Gigabit RJ45 ports, 4G Combo ports, 4G SFP fiber ports, and 1 console port. Support Web, CLI (Console Port, Telnet, SSH), SNMP, RMON, and Dual Image bring powerful management capabilities. With abundant layer 2 management features supported, the SR-SG3428FC is capable of delivering high throughput to even the most demanding edge-of-network workgroups, while in small networks it can act as a backbone for Gigabit switches and high-speed servers. 4 SFP slots provide greater network flexibility. The SR-SG3428FC is designed exclusively for the networking needs of growing busi- nesses, with an extensive suite of management and security features available. These devices are cost-effective for small and medium-sized businesses, providing ideal solu- tions for a variety of network scenarios. Features Supports IEEE 802.3i, 802.3u, 802.3ab, 802.3z, 802.3x , 802.3az. Provides 28 10/100/1000Mbps RJ45 ports, 4 Gigabit SFP fiber ports. Supports MAC address auto-learning and auto-aging. Store and forward mode operates. LED indicators for monitoring power, link/activity. Supports QoS, port mirroring, link aggregation protocol. 19 inches full metal iron shell and internal power adapter design, suitable for rack installation. Energy saving and low noise Following the IEEE 802.3az (Energy Efficient Ethernet) standard, it greatly reduces the power consumption of the equipment and is green and energy-saving. Fully considering the low noise requirements of the user environment, the fanless design is adopted to monitor the temperature in the system in real time, which can effectively reduce noise pollution. Simple and flexible operation and maintenance management Supporting unified management of the entire network configuration and web management can simplify user operations and improve deployment reliability. Supports power alarm and port status alarm, users can set the alarm mode corresponding to the power supply of the device and the port, which is convenient for user operation and maintenance. Supports perfect SNMP management, support VCT, DDM (Digital Diagnostic Monitoring) and other features, quickly detect network faults and reduce the difficulty of operation and maintenance. It supports the function of sending information to the server. The logs generated by the device are sent to the information server in a unified manner. Through the unified management and control of the information server, the flexible output of information is realized, which is convenient for monitoring the running status of the equipment and locating faults. Enhanced protection, safe and controllable Supports a variety of security protection mechanisms, provides various DOS-type attack defense technologies such as SYN Flood, Land, ICMP Flood, supports BPDU Filter, BPDU Guard, avoids accidental topology loops and illegal edge devices become root nodes, preventing unnecessary topological oscillations. In terms of anti-attack measures for the user layer, it supports both port-based and VLAN-based DHCP snooping and IP Source Guard. The combination of the two can effectively prevent illegal address spoofing such as MAC, IP, and MAC IP, and can also reduce DOS risks of attacks. Supports the source MAC address learning restrictions of port-based and VLAN-based, effectively preventing user source MAC spoofing from impacting device MAC table entries, causing normal users to fail to learn the MAC table and flooding. Through the DAI function, the attack source can be prevented from attacking the network through ARP loopholes, which can minimize the intermittent and frequent disconnection in the process of network use, and increase the security and availability of the network. Supports custom ACL, more flexible to match the Ethernet header or IP header of the packet according to user requirements. Provides a complete ACL policy, can classify data according to various fields of the packet, and use different policies for forwarding. It supports standard 802.1X authentication access, and at the same time supports extended 802.1X authentication access, which can effectively prevent IP conflicts and PC cloning, and realize extended and enhanced functions such as static IP address delivery. It supports Web Portal authentication access, and can push Web Portal page authen- tication for access users based on Http and Https two protocols. Redundant backup, stable and reliable The first to support the industry-standard ERPS ring network solution, support sin- gle-ring networking mode, <20ms convergence speed, and achieve carrier-class reliability. Multi-process MSTP is supported, each process can run different spanning tree pro- tocols, and the number of access sub-rings is increased at the same time. The new access ring can be realized by creating a new MSTP process, which does not affect the original service traffic and reduces network impact. Built-in lightning protection technology, service ports provide 4KV lightning protec- tion capability, effectively resist lightning strikes, more adaptable to harsh environments than ordinary switches, and greatly reduce the damage rate of equipment. VLAN expansion, abundant and diverse Supports common QinQ and flexible QinQ technologies, giving users maximum freedom to configure QinQ policies. Supports multiple VLAN types such as protocol VLAN, MAC VLAN and Voice VLAN, plays a role in multi-service converged networks.
