Huawei S220-48P4X is a managed switch from the eKitEngine series. It comes with 48 gigabit Ethernet ports (10/100/1000 Mb/s) and 4 SFP+ slots (10 Gb/s). All Ethernet ports support PoE+, with a maximum power per port of 15.4 W for 802.3af or 30 W for 802.3at. The total power budget for the entire device is 380 W, significantly more than what the S110 series offers. The switch provides robust network security, supporting various authentication methods (based on MAC address or 802.1X) and protection against external attacks. Management can be done through the Web UI, CLI, SNMP, and cloud-based management, including the Huawei eKit app. The S220-48P4X is mainly intended for use as an access switch in networks with multiple APs, offering a large power budget and high throughput thanks to its SFP+ slots. In smaller networks, it can serve as the primary switch, providing both PoE and basic management capabilities. 48x gigabit Ethernet, 4x SFP+ The switch is equipped with 48 gigabit Ethernet ports (10/100/1000 Mb/s) and 4 SFP+ slots (10 Gb/s). It has a switching capacity of 176 Gb/s and a packet forwarding speed of 131 Mp/s. The SFP+ slots provide high-speed connectivity, up to 10 Gb/s, enabling connections between network segments or efficient devices such as servers. 48 PoE+ outputs On all Ethernet ports, there is PoE+ power output available. The maximum power output per port, according to standards, is 15.4 W for 802.3af or 30 W for 802.3at. The total power budget for the entire device is 380 W, significantly more than what solutions from the S110 series offer. This is sufficient for connecting 24 APs using the 802.3af standard, and in most cases, you can even conne more devices, as power consumption typically remains below 15 W. The use of PoE allows you to power and transmit data through an Ethernet cable. With this type of switch, you only need to run one cable to each access point, eliminating the need for additional power supplies. Layer 2 management The device provides numerous Layer 2 management features, such as VLAN support, multicast support (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 standard ERPS (Ethernet Ring Protection Switching) 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 has safeguards against attacks targeting users, including DHCP server attacks, IP/MAC spoofing, DHCP request floods, and DHCP CHADDR attacks. Management can be performed through the Web UI, CLI, or using SNMP (v1, v2c, v3) / SSHv2.0. S220 series devices can also be managed in the cloud, allowing you to additionally utilize the Huawei eKit app. Usage The S220-48P4X is designed to function as an access switch in networks consisting of multiple eKitEngine APs. Access to Layer 2 management allows you to control and monitor the operation of the entire network. With eKitEngine solutions, management can be consolidated into a single interface, simplifying system configuration and maintenance. Thanks to its large power budget, the S220-48P4X allows you to easily conne 24 access points, and in most situations, even more. The switch is suitable for large networks, such as those found in hotels or schools. On the other hand, with access to management features, it can function as the sole switch in small and medium-sized networks, eliminating the need for separate core and access switches.
