Description

The Juniper EX4400 is a fixed-configuration 1U Layer 2/Layer 3 switch for campus and branch access and aggregation layers where high-density 1GbE non-PoE connectivity is needed. It suits Virtual Chassis or EVPN-VXLAN campus fabrics with 100G uplinks.

This EX4400-48T provides 48 x 10/100/1000BASE-T RJ-45 ports and two 100GbE QSFP28 uplink/stacking ports. Switching capacity is 348 Gbps unidirectional (696 Gbps bidirectional), with 517 Mpps of Layer 2/Layer 3 throughput at 64-byte packets. It is powered by a 550 W AC power supply with front-to-back (AFO) airflow, and the access ports are non-PoE. A 2.2 GHz quad-core x86 CPU, 4 GB ECC DRAM and a 112,000-entry MAC address table support the feature set.

Up to 10 units can be interconnected as a single Virtual Chassis over a 400 Gbps backplane. One expansion slot accepts the EX4400-EM-4S (4x SFP+), EX4400-EM-4Y (4x SFP28) or EX4400-EM-1C (1x QSFP28) uplink modules. MACsec AES256 is available with an optional licence.
