It puts 24 Gigabit Ethernet ports with PoE+ on every port into a 1U chassis, sized for the branch office, school, or wiring closet that does not need a full 48-port panel but still needs real uplink headroom for a modern phone, access-point, and camera fleet.\u003c\/p\u003e\u003cp\u003eEach access port delivers up to 30 W of PoE+, with a 740 W PoE budget on the single included power supply and up to 1,440 W with a second 920 W supply installed. Fast PoE and perpetual PoE keep endpoints powered through switch reboots and bring power back quickly on power-up — the behavior a closet full of IP phones and APs actually needs. Uplinks are 4 x 10GbE SFP+ ports plus 4 x 25GbE SFP28 ports that serve as additional uplinks or as Virtual Chassis stacking ports, linking up to ten EX4100 switches into one logical device. Switching capacity is 328 Gbps with 244 Mpps of throughput.\u003c\/p\u003e\u003cp\u003eThe EX4100 runs Junos OS with a full Layer 2\/Layer 3 feature set, extends EVPN-VXLAN fabrics out to the access layer, and adds MACsec AES-256 link encryption and group-based-policy microsegmentation for endpoint-level security. It is built for Juniper Mist Wired Assurance: onboard, provision, and manage it from the Mist cloud, with Marvis AI assistance and flow-based telemetry for per-flow visibility. It also runs standalone under Junos CLI — a Mist subscription is an optional management layer, not a requirement, and is not included with this listing.\u003c\/p\u003e\u003cp\u003eHardware is serviceable in the rack: the switch includes one 920 W AC power supply (JPSU-920-AC-AFO, front-to-back airflow) and redundant field-replaceable fan modules installed, supports a second hot-swappable supply for redundancy and full PoE budget, and fits a standard 1U rack space at 17.36 in wide.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey specifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e24 x 10\/100\/1000BASE-T RJ45 access ports, all PoE+ (IEEE 802.3at), up to 30 W per port\u003c\/li\u003e\n\u003cli\u003ePoE budget: 740 W with one power supply; up to 1,440 W with two power supplies\u003c\/li\u003e\n\u003cli\u003eUplinks: 4 x 10GbE SFP+ plus 4 x 25GbE SFP28 (uplink \/ Virtual Chassis stacking)\u003c\/li\u003e\n\u003cli\u003eSwitching capacity 328 Gbps; throughput 244 Mpps\u003c\/li\u003e\n\u003cli\u003eVirtual Chassis technology — stack up to 10 EX4100 switches as one logical device\u003c\/li\u003e\n\u003cli\u003eJunos OS — full Layer 2 and Layer 3 feature set, EVPN-VXLAN to the access layer\u003c\/li\u003e\n\u003cli\u003eMACsec AES-256, group-based-policy (GBP) microsegmentation, flow-based telemetry\u003c\/li\u003e\n\u003cli\u003eJuniper Mist Wired Assurance and Marvis AI ready (Mist subscription sold separately, not included)\u003c\/li\u003e\n\u003cli\u003e1U rack-mountable: 17.36 x 1.72 x 13.78 in (base unit); 15.05 in deep with power supply installed\u003c\/li\u003e\n\u003cli\u003e4 GB ECC DRAM, 8 GB storage, 1.7 GHz ARM CPU\u003c\/li\u003e\n\u003cli\u003eOperating temperature 32 to 113°F (0 to 45°C)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's included:\u003c\/strong\u003e Refurbished EX4100-24P switch with 1 x JPSU-920-AC-AFO 920 W AC power supply and redundant fan modules installed, with Standard software.
