Huawei NetEngine AR550‑24P‑S Industrial PoE Router Full Product Description

1. Short Overview

Naming & Variant Breakdown

• AR550‑24P‑S: High‑density industrial router with24×GE PoE+ RJ45 ports, multiple GE‑SFP uplink slots, DI/DO alarm terminals; no embedded cellular or Wi‑Fi radio module.

Difference vs AR550‑8P‑S: AR550‑24P‑S provides 24 PoE+ ports for higher‑density terminal access, larger chassis and higher total PoE power budget, suitable for sites deploying many IP cameras, PoE sensors and field IoT terminals. Protection rating IP30, for indoor cabinet installation, not for direct outdoor exposure. No container‑based edge‑computing function.

Core Differentiators

1. Fan‑free passive‑cooling industrial hardware, wide operating temperature −40 °C ~ +70 °C, IP30 enclosure, compliant with IEC61850‑3 / IEEE1613 power‑industry anti‑interference EMC standards.
2. 24‑port GE PoE+ (IEEE 802.3at), each port max 30 W output. High total PoE budget eliminates extra external PoE injectors for large‑quantity industrial cameras and PoE sensors.
3. Flexible uplink via multiple GE‑SFP optical slots for long‑distance fiber backhaul; all service ports are software configurable as WAN or LAN for flexible networking design.
4. Rich industrial auxiliary interfaces: DI/DO alarm I/O, Console debugging port, USB port for configuration backup and batch deployment. Dual‑redundant wide‑voltage DC power input improves power‑supply reliability for unmanned sites.
5. Integrated routing‑switching security suite including firewall, ACL and high‑performance IPsec VPN; supports batch configuration, remote firmware upgrade and visualized site monitoring via eSight.
