Juniper Networks EX4400-48P EX4400 48-Port GbE PoE++ 90W 2x 100G Mist AI Layer 3 Switch

The Juniper Networks EX4400-48P is a 1RU Layer 2/3 managed PoE++ access switch from the EX4400 Series, designed for enterprise campus and branch deployments requiring high-density 1G PoE++ connectivity for Wi-Fi 6/6E access points, IP phones, and high-power IoT devices with cloud-managed Mist AI operations. The switch provides 48 10/100/1000BASE-T PoE++ RJ-45 ports with IEEE 802.3af/at/bt support at up to 90W per port and a 1,400W total PoE budget from the included power supply, alongside two dedicated 100GbE rear ports for Virtual Chassis stacking or uplinks configurable with 100G or 40G optics. An optional extension module adds four 1G/10GbE SFP+, four 1G/10G/25GbE SFP28, or one 100GbE QSFP28 port. Virtual Chassis supports up to 10 EX4400 switches managed as a single logical device with hitless failover. Running Junos OS with Mist AI integration, the EX4400-48P supports EVPN-VXLAN to the access layer, MACsec AES-256, group-based policy microsegmentation, flow-based telemetry, and ZTP onboarding via Juniper Mist Wired Assurance. Fast PoE delivers power to connected devices within seconds of the switch powering on. Layer 3 features include BGP, OSPF, IS-IS, VRRP, and static routing.
