USG9520-AC - Kino Technology Limited

The Huawei USG9520‑AC is a carrier‑grade terabit‑level next‑generation firewall of the USG9500 series with AC power input, adopting centralized‑control and distributed‑forwarding architecture within a 5U 19‑inch standard rack‑mount chassisManualsLib. Optimized for enterprise data‑center rooms and equipment premises with AC power infrastructure, it is designed for large‑scale data centers, cloud platforms, large enterprise headquarters and giant campus networks. This modular security gateway integrates stateful firewall, IPS, anti‑virus, anti‑DDoS mitigation, NAT and VPN capabilities. Redundant hot‑swappable key components deliver carrier‑grade reliability for mission‑critical network perimeter security protection.

High‑Performance Distributed Modular Architecture

Equipped with 3 service slots for flexible deployment of LPU line‑processing boards and SPU service‑processing boards, supporting 1GE,10GE,40GE,100GE high‑speed interface cards for on‑demand capacity expansion. Maximum firewall throughput reaches 120 Gbit/s, supporting up to 160 million concurrent sessions to handle massive real‑time network traffic华为企业业....
Comprehensive Multilayer Security Protection

Delivers stateful firewall filtering, intrusion prevention, anti‑virus, anti‑DDoS defense, large‑scale NAT, IPsec/SSL VPN, fine‑grained application identification and granular access control. Supports multiple virtual firewall instances for multi‑tenant isolation and full‑featured IPv6 security defense to adapt to cloud‑virtualized networking scenarios.
Carrier‑Grade High‑Availability Design

Dual‑MPU 1:1 main‑standby redundancy, 1+1 redundant hot‑swappable AC power modules and hot‑swappable fan trays. Supports device‑level active‑standby and load‑balancing deployment, online board replacement and non‑disruptive software upgrade, achieving 99.999% system availability for uninterrupted critical‑service operation. Designed for standard 100‑240V AC power distribution systems.
Rich Networking & Flexible Deployment

Supports routing mode, transparent mode and hybrid composite deployment. Provides link load balancing, ISP‑aware routing, intelligent egress selection and advanced QoS traffic management. Supports local CLI, SSH, HTTPS web‑UI management, and centralized administration via Huawei U2000 / VSM security management platform.
5U AC Chassis Hardware

5U height 19‑inch standard rack‑mount AC‑optimized chassis, higher form‑factor than the 4U DC versionManualsLib. Hot‑swappable power, fan and service boards enable maintenance without service interruption, suitable for enterprise data‑center rooms deploying AC power infrastructure.
