Product overview

The HPE Aruba Networking CX 4100i JL818-61101 (JL818A) is a high-performance Layer 3 managed switch designed for enterprise access layer deployments. It provides 20x 10/100/1000Base-T PoE Class 4 ports (30W each) and 4x PoE Class 6 ports (60W each), plus 4x multi-rate SFP+ uplinks supporting 100M/1G/10G speeds. With a maximum PoE budget of 360W at lower temperatures (derating to 200W at 70°C), internal power supply, and rack-mountable 1U form factor, it powers demanding Wi-Fi 6 APs, IP cameras, and IoT devices. Enhanced security features, IPv6 support, traffic prioritization, and built-in high-speed uplinks simplify deployment. Fan-cooled operation ensures reliability in harsh environments (-40°C to +70°C), with immunity to EMI, surges, and shocks per industrial standards. No software licensing required reduces TCO for scalable campus and branch networks.

24x GbE PoE ports: 20 Class4 (30W), 4 Class6 (60W).
4x multi-rate SFP+ uplinks support 100M/1G/10G speeds.
360W PoE budget at <50°C, derates to 200W at 70°C.
Layer 3 managed with IPv6, no software licensing needed.
Industrial-grade: -40°C to +70°C, EMI/shock immunity.
Rack-mountable 1U with internal power supply included.
