Description

The EX4400-48MXP is a 1 RU multigigabit access switch in the Juniper EX4400 range, built for enterprise campus and branch access, high-density Wi-Fi 7 access point deployments and smart buildings running lighting, IoT sensors and HVAC on PoE.

It provides 12 ports of 100M/1/2.5/5/10GbE and 36 ports of 100M/1/2.5GbE, all with IEEE 802.3bt PoE++ at up to 90 W per port. The 2000 W AC power supply gives a PoE budget of 1650 W at 220 V with one supply and 3600 W with two supplies. Switching capacity is 1020 Gbps bidirectional at 758 Mpps, with 4 GB DRAM and 20 GB storage.

Uplinks and stacking are handled by a hot-swappable extension module slot. Choose the EX4400-EM-1C (1x100GbE QSFP28), EX4400-EM-4S (4x10GbE SFP+) or EX4400-EM-4Y (4x25GbE SFP28). Virtual Chassis joins up to 10 members as one logical device over a 400 Gbps interconnect. The switch runs Junos OS and supports EVPN-VXLAN to the access layer, MACsec AES-256 and cloud management with Juniper Mist Wired Assurance.
