About the Juniper Networks EX4400-24X Ethernet Switch
With a switching capacity of 1.76 Tbps and forwarding throughput of 1.04 Bpps, the Juniper Networks EX4400-24X Ethernet Switch delivers line-rate performance for demanding enterprise environments. This 1U rack-mountable switch from Juniper features 24 ports of 25GbE SFP28 connectivity, complemented by 4 x 100GbE QSFP28 uplink ports and 2 x 400GbE QSFP-DD Virtual Chassis ports for seamless scalability. The EX4400-24X (part number EX4400-24X) is part of Juniper's proven EX Series product line, offering a MAC address table capacity of 288,000 entries and supporting comprehensive Layer 2 and Layer 3 protocols including RSTP, MSTP, VSTP, VLAN, QinQ, LACP, LLDP, 802.1X, MACsec, IPv4/IPv6, OSPF, IS-IS, BGP, RIP, ECMP, BFD, and VRRP.
Network engineers and infrastructure teams select the EX4400-24X for its robust feature set and operational reliability. The switch incorporates advanced security mechanisms including MACsec (IEEE 802.1AE), storm control, DHCPv4/v6 snooping, Dynamic ARP Inspection, and IP Source Guard to protect against Layer 2 and Layer 3 threats. Quality of Service capabilities include 8 queues per port with support for DSCP, 802.1p, strict priority, and weighted round-robin scheduling. The platform runs Junos OS and supports modern automation and management protocols including Zero Touch Provisioning (ZTP), NETCONF, YANG, OpenConfig, and REST API, with Juniper Apstra integration for intelligent infrastructure orchestration. Overlay networking capabilities include EVPN-VXLAN for flexible virtualization deployments.
Operational resilience is built into every component. The EX4400-24X features redundant, hot-swappable AC power supplies and field-replaceable, hot-swappable fan trays with configurable front-to-back and back-to-front airflow options, ensuring continuous uptime in production environments. The switch operates reliably across standard data center temperature ranges of 0°C to 45°C.

Frequently Asked Questions about Juniper Networks EX4400-24X Ethernet Switch
Does the Juniper Networks EX4400-24X Ethernet Switch support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations in advance, or provide remote commissioning. Add commissioning to your RFQ.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises later.
Is the support global?
Yes — manufacturer hardware support is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
