The Huawei S220-48T4X is a managed switch from the eKitEngine series. It is equipped with 48 gigabit Ethernet ports (10/100/1000 Mbps) and 4 SFP+ slots (10 Gbps). It supports Layer 2 management, including protocols such as STP (STP/RSTP/MSTP) and ERPS (Ethernet Ring Protection Switching). It provides high network security, supports various types of authentication (based on MAC address or 802.1X), and is protected against various external attacks. You can manage the device using the Web UI, CLI, or SNMP. Additionally, it supports cloud management and the Huawei eKit application. The S220-48T4X has a built-in AC power supply, with a maximum power consumption of 44.3 W. It utilizes active cooling with intelligent fan speed adjustment. The device is suitable as an advanced access switch in locations where you don't need PoE or as the main switch in smaller networks. 48x gigabit Ethernet, 4x SFP+ The switch is equipped with 48 gigabit Ethernet ports (10/100/1000 Mbps) and 4 SFP+ slots (10 Gbps). It has a switching capacity of 176 Gbps and a packet forwarding rate of 131 Mpps. The SFP+ slots provide high-speed connectivity (up to 10 Gbps), allowing for the connection of multiple network segments or high-performance devices such as servers. Layer 2 management The device provides numerous Layer 2 management features, such as VLAN support, multicast handling (IGMP Snooping), Quality of Service (QoS) functions, and Access Control Lists (ACLs). It supports Spanning Tree protocols (STP/RSTP/MSTP) as well as the modern ERPS (Ethernet Ring Protection Switching) standard defined in the ITU-T G.8032 standard. The switch provides essential network security measures. It protects against DoS attacks such as SYN flood, Land, Smurf, and ICMP flood. Additionally, it includes protection against attacks targeting users, such as DHCP server attacks, IP/MAC spoofing, DHCP request flood, and DHCP CHADDR attacks. Management is conducted through the graphical Web interface, CLI, or using SNMP (v1, v2c, v3) / SSHv2.0. Devices from the S220 series can also be managed in the cloud, and in this case, you can additionally use the Huawei eKit app. Usage The primary use of the S220-48T4X is as an access switch in locations where PoE is not required. It is best suited for networks based on eKitEngine solutions, as using devices from the same series simplifies configuration and subsequent management. In larger networks, the S220-48T4X can also serve as an aggregation switch, acting as an intermediary between the core switch and access switches.
