Technology
This Aruba switch runs on the programmable HPE Aruba Networking CX Operating System (AOS-CX), ensuring consistent operation across the CX portfolio. It features a dedicated ASIC for low latency and adaptive power consumption. The switch supports modern standards including sFlow, REST APIs, and IEEE 802.3at/af PoE, making it ready for software-defined networking and IoT integration.
Working Principle
The switch operates at Layer 2 of the OSI model, providing Ethernet switching, VLAN segmentation, traffic prioritization, and PoE management. It uses hardware-based forwarding to achieve high throughput with minimal latency. The built-in PoE controller dynamically allocates power to connected devices such as wireless access points and IP cameras, ensuring efficient energy use.
Application & Usage
Ideal for:
- Enterprise branch offices and campus access layers
- Mid-market and small business networks
- IoT and digital workplace deployments
- Unified wired and wireless access environments
- Quiet environments such as libraries, classrooms, and clinics
