HPE Aruba R8N89B | CX 6000 12G Class4 PoE 139W Switch
Compact PoE Access Switching for Business Networks
The HPE Aruba CX 6000 R8N89B is a fully managed Layer 2 access switch designed for enterprise branch offices, SMBs, and space-constrained environments requiring quiet Gigabit Ethernet connectivity and Power over Ethernet. It features 12 10/100/1000BASE-T Class 4 PoE access ports supporting IEEE 802.3af and IEEE 802.3at standards with a 139W PoE power budget. Dedicated uplinks consist of two 1G SFP ports and two 1GbE RJ45 ports. Its compact, fanless 1U chassis is built for silent deployment on desktops, walls, or racks.
Key Benefits and Features
- Class 4 PoE Connectivity: Twelve Gigabit Ethernet access ports provide up to 30W per port for powering IP phones, wireless access points, and security cameras.
- 139W PoE Budget: Delivers robust centralized power allocation across connected PoE edge devices.
- Flexible Built-in Uplinks: Features two 1G SFP ports for fiber connectivity and two 1GbE RJ45 ports for copper uplinks without sacrificing access ports.
- Silent Fanless Operation: Acoustic-free hardware design enables deployment directly in open office environments, retail spaces, or noise-sensitive areas.
- Enterprise OS & Management Flexibility: Powered by AOS-CX, supporting Web GUI, industry-standard CLI, REST APIs, sFlow, and cloud or on-premises management.
