Description
The Juniper EX4100-F-12P is a compact, fanless, cloud-ready Ethernet switch designed for enterprise branch, remote office, and campus access deployments. Featuring 12x 1GbE PoE+ access ports, it delivers up to 30W per port with a total PoE budget of up to 300W when paired with an external AC power adapter and uplink-connected PSE devices.
Powered by Mist AI™ and Juniper Mist Wired Assurance, the EX4100-F-12P simplifies operations with AI-driven automation, real-time telemetry, and Marvis Virtual Network Assistant for proactive troubleshooting. It supports advanced features such as EVPN-VXLAN, standards-based group-based policy (GBP) microsegmentation, and flow-based telemetry for enhanced visibility and security.
With Virtual Chassis technology, up to 10 EX4100-F switches can be managed as a single device, delivering scalable, pay-as-you-grow networking. Combining high performance with silent, fanless operation, the EX4100-F-12P is ideal for modern, secure, and AI-driven access networks.
