High‑Performance Hardware & Line‑Rate Forwarding

Built on a high‑speed hardware architecture, the H3C S5590‑EI switch series delivers up to 24Tbps switching capacity and 672Mpps to 1110Mpps packet forwarding rate for non‑blocking data transmission. Supporting line‑rate performance on all ports, the series ensures smooth transmission for large files, video surveillance, VoIP, industrial communication, and multi‑service concurrent traffic without packet loss or delay.

Rich Port Models & Flexible Configuration

The S5590‑EI series includes multiple models to meet various networking requirements: 24/28/48‑port Gigabit RJ45, SFP fiber, and PoE+ versions, plus 4/6/8‑port 10G SFP+ uplinks, 25G SFP28, and 40G/100G QSFP28 high‑speed interfaces. All models support combo ports, modular power supplies, dual fan modules, and one extension slot for optional interface cards or service modules, enabling highly flexible deployment for access, aggregation, and core layers.

PoE+ Power Supply for Intelligent Devices

PoE models of the H3C S5590‑EI series support IEEE 802.3af/at PoE+ with up to 30W per port, providing stable remote power for APs, IP cameras, VoIP phones, and IoT terminals. Features including Fast PoE and Perpetual PoE ensure fast power‑on and uninterrupted power supply during switch reboot, greatly improving stability for surveillance and wireless network systems.

IRF2 Virtual Stacking & M‑LAG High Reliability

Supporting IRF2 (Intelligent Resilient Framework) technology, up to 9 physical switches can be virtualized into one logical device, simplifying management, improving scalability, and achieving 1:N device redundancy. The S5590‑EI series also supports M‑LAG cross‑chassis link aggregation to realize dual‑active access, load balancing, and zero service interruption during upgrades, fully meeting carrier‑grade reliability requirements.

Complete IPv4/IPv6 Routing & Multi‑Service Support

The S5590‑EI switches support complete hardware‑based IPv4/IPv6 dual stack and rich routing protocols including static routing, RIP, OSPF, BGP, and IS‑IS. The series also supports VxLAN, EVPN, MPLS VPN, multicast, and QinQ, making it ideal for modern virtualized data centers, cloud networks, and large campus interconnection architectures.

Enterprise‑Grade Security & Access Control

Equipped with comprehensive security features, the S5590‑EI series supports 802.1X authentication, MAC authentication, Portal authentication, dynamic IP/MAC/VLAN/port binding, ACL, uRPF anti‑spoofing, DAI, and CPU protection. It also supports 256‑bit MACsec hardware encryption and EAD endpoint admission control to protect data transmission and block unauthorized access effectively.

Smart Management & O&M Tools

The H3C S5590‑EI series supports multiple management methods: Web GUI, CLI, Telnet, SSH 2.0, SNMP v1/v2/v3, and iMC intelligent management system. Built‑in SmartMC enables unified visualized management for large‑scale edge devices. The switch also supports Telemetry, NetStream, sFlow, BFD, and VCT cable diagnostics to simplify fault location and network optimization.

Redundant Hardware & Rugged Reliability

Designed for 24/7 continuous operation, the S5590‑EI series uses dual modular power supplies (AC/DC optional), dual hot‑swappable fan modules, overcurrent/overvoltage/overheating protection, and dual Boot ROM backup. It supports 10KV lightning protection and works reliably in temperatures ranging from -5°C to 45°C, ensuring stable performance in harsh industrial and outdoor cabinet environments.
