Huawei USG5520E

Product Overview

Key Features

1. High‑performance carrier‑grade forwarding capability

   Adopts distributed multi‑core parallel packet‑processing hardware architecture with one‑pass multi‑threat inspection technology. It completes firewall, IPS and anti‑virus scanning within one processing cycle, maintaining stable performance under ultra‑heavy mixed traffic of deep security inspection and massive real‑world business flows. Standard 19‑inch 4U rack‑mount chassis fits standard equipment‑room cabinet deployment.
2. Multi‑layer comprehensive threat defence

   Provides stateful firewall filtering, IPS intrusion prevention, gateway anti‑virus, anti‑spam filtering, anti‑DDoS attack mitigation, URL filtering and DPI‑based fine‑grained application identification. Recognizes thousands of mainstream applications including instant messaging, P2P download, video streaming and social‑network services. Supports granular security policy enforcement based on user identity, application type, time schedule and bandwidth quota. Supports massive virtual firewalls for logical multi‑tenant isolation, as well as complete IPv4‑IPv6 dual‑stack security defence and IPv6 transition technologies.
3. High‑density modular expansion and diversified VPN connectivity

   Equipped with multiple hot‑swappable service board slots and interface module slots. Supports high‑density GE electrical/optical, 10GE SFP+, 40GE QSFP+ and other optional modules to satisfy complex large‑scale multi‑scenario access requirements. Supports IPsec, L2TP, GRE, MPLS and SSL VPN for site‑to‑site interconnection and massive‑scale remote‑user access. Built‑in NAT, QoS traffic scheduling and comprehensive IPv4/IPv6 routing protocols fully meet large‑enterprise and carrier‑class complex networking demands. Supports full‑redundant hot‑swappable AC/DC power supply and hot‑swap fan modules for in‑service maintenance without business interruption.
4. Diversified O&M and centralized management

   Supports Console CLI, HTTPS web‑UI, SNMP for local and remote device maintenance. Compatible with Huawei centralized security management platform for unified configuration deployment, policy synchronization and real‑time security‑event monitoring. Multi‑dimensional traffic and security‑event reports simplify daily operation and audit work. UTM security functions are activated via license subscription. Powered by mature VRP operating system to guarantee long‑term stable core‑network operation.
5. 4U carrier‑grade high‑reliability hardware design

   Standard 19‑inch 4U chassis, supports multiple hot‑swappable AC 100‑240 V and DC ‑48~‑60V power input with power redundancy. Reserved Console management port, multiple USB 2.0 ports and Micro‑SD card slot for auxiliary management and local log storage. Supports routing mode, transparent mode, mixed deployment, as well as active‑standby and active‑active HA cluster backup.
