The Aruba CX 4100i Switch Series (part number JL912A) delivers enterprise-grade power delivery across all 48 ports, supporting both IEEE 802.3at PoE+ and IEEE 802.3bt PoE++ standards to power demanding access layer devices without external injectors. This fixed-configuration access layer switch is engineered for network engineers and IT procurement teams building scalable, resilient campus and branch infrastructures with unified power and connectivity in a compact 1U form factor.
Built on Aruba's proven CX platform, the JL912A combines high-performance switching with advanced security and automation capabilities. With a switching capacity of 176 Gbps and forwarding rate of 130.9 Mpps, the CX 4100i efficiently handles voice, video, and data traffic across mixed device deployments. The 48 x 10/100/1000BASE-T PoE+ ports are complemented by 4 x 1G/10G SFP+ uplink ports, enabling flexible connectivity to core infrastructure. Aruba Central cloud management, REST API support, and Python scripting integration streamline operations and enable rapid policy deployment. Security features including 802.1X, Dynamic Segmentation, RADIUS authentication, and Dynamic ARP Protection protect against unauthorized access and network threats, while IEEE 802.1p and DSCP-based QoS with 8 queues per port ensures critical applications receive priority treatment.
