Huawei NetEngine AR550‑24P‑S Industrial Integrated Gateway Router

Product Overview

Key Features

• Rugged fan‑less industrial hardware: Adopts passive fan‑free cooling, supports DIN‑rail installation, IP20 enclosure. Resists shock, vibration and severe electromagnetic interference for cabinet‑mount field deployment.
• High‑density PoE‑capable port design: 24×GE PoE+ RJ45 access ports supply power for IP cameras, industrial wireless APs and PoE‑enabled field terminals; multiple Gigabit combo SFP/RJ45 uplink interfaces support copper or long‑distance fiber transmission.
• Full‑feature routing‑switching capacity: Supports IPv4/IPv6 dual‑stack, static routing, RIP, OSPF, BGP; comprehensive Layer‑2 functions including 802.1Q VLAN, STP/RSTP/MSTP, LACP, IGMP Snooping. Implements IEEE 1588v2 PTP precision time synchronization for industrial time‑sensitive services.
• Built‑in multi‑dimensional security capability: Stateful firewall, ACL filtering, IPsec/GRE/L2TP VPN, anti‑DDoS protection, access‑control policy, realizing encrypted site‑to‑site communication for distributed industrial branches.
• Flexible WAN access & link reliability: Supports Ethernet access and optional 4G/LTE cellular backup link. Provides link quality detection, multi‑link load‑balancing and automatic fail‑over to improve network availability for unattended remote sites.
• Redundant power & hardware alarm: Dual terminal‑block wide‑range DC power input (9.6‑60 V DC) for power redundancy; digital DI/DO alarm I/O terminal outputs hardware fault signals. Equipped with USB 2.0 port for configuration backup and on‑site maintenance.
• Diversified O&M modes: Console CLI, embedded Web‑UI, SNMP v1/v2c/v3, Syslog; compatible with Huawei iMaster NCE‑Campus for centralized remote management of mass distributed industrial gateways.
