HPE Aruba CX 6000 R8N85A - 48-Port Gigabit PoE+ Managed Switch
The R8N85A is a Layer 2 managed access switch with 48 Gigabit Ethernet PoE+ ports and four 1GbE SFP uplinks, designed for branch offices and small-to-midsize enterprises deploying IP surveillance, wireless access points, and VoIP infrastructure. It delivers 370W of Class 4 PoE budget across all ports, supporting up to 30W per device for high-power endpoints like PTZ cameras and Wave 2 APs. Built on Aruba's AOS-CX operating system with a programmable ASIC architecture, this switch fits standard 1U rack mounting and runs on a fixed power supply with integrated cooling fans.
Key Features
- 370W PoE+ budget powers up to 12 high-wattage devices simultaneously - supports IEEE 802.3at Class 4 at 30W per port for PTZ cameras, video phones, and enterprise Wi-Fi 6 access points
- Four dedicated 1GbE SFP uplinks eliminate copper distance restrictions - allows fiber connections to distribution switches up to 10km away using standard LC SX/LX transceivers
- Static routing and ACL support enables VLAN segmentation without dedicated L3 router - handles basic inter-VLAN routing and filtering for small networks with up to 512 IPv4/IPv6 routes
- 12.38MB packet buffer with flexible queue configurations - handles traffic bursts from high-density wireless deployments and reduces latency for real-time applications like video conferencing
