EX3400-24T Overview

Juniper Networks EX3400 Ethernet Switch delivers a highperformance, flexible, and costeffective solution for today’s most demanding converged data, voice, and video enterprise access environments

To simplify network operations, the EX3400 is hardware-ready1 to act as a satellite device to support a Juniper Networks Junos Fusion Enterprise deployment, which can combine several wiring closets into one logical management platform. The EX3400 also supports Juniper Networks Virtual Chassis technology, allowing up to 10 switches to be interconnected over uplink ports and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments.

The Juniper Networks® EX3400 Ethernet Switch with Juniper Networks Junos® Fusion Enterprise and Virtual Chassis technology provides enterprises with the flexibility and ease of management that previously was only available with higher-end access switches. The fixed-configuration EX3400 supports a number of key features, including:
- Junos Fusion Enterprise allows large numbers of EX3400 switches to be configured as satellite devices that connect to an EX9200 core aggregation switch to create a single logical device.
- 24-port and 48-port models with and without Power over Ethernet (PoE/PoE+) are for campus wiring closet deployments
- Data center-optimized cooling options offer both front-to-back and back-to-front airflows, making the EX3400 suitable for GbE data center access deployments.
- Two redundant, field-replaceable power supplies each provide up to 920 watts of power.
- 24-port data center models are included for metro deployments.
- Four dual-mode (GbE/10GbE) small form-factor pluggable transceiver (SFP/SFP+) uplink ports and two 40GbE QSFP+ ports are available.
- Uplink ports can be configured as Virtual Chassis interfaces and connected via standard 10GbE/40GbE optic interfaces (40GbE uplink ports are preconfigured by default as Virtual Chassis ports).
- Comprehensive Layer 2 functionality with RIP and static routing is provided.
- A compact, 13.8-inch deep 1 U form factor supports flexible deployment options.
- An easy-to-manage solution includes centralized software upgrades and a single management interface.
- Support is available for the same consistent modular Juniper Networks Junos operating system control plane feature implementation used by all other Juniper fixed-configuration Juniper Networks EX Series Ethernet Switches.
- Support Is provided for Layer 3 (OSPF v2, IGMP v1/v2/v3, PIM, VRRP, Q-in-Q, BFD, virtual router) via an enhanced feature license (optional license required).
- Support is available for IPv6 management, including neighbor discovery, stateless auto configuration, telnet, SSH, DNS, system log, NTP, ping, traceroute, ACL, CoS static routing, and RIPng.
- IPv6 routing features (OSPFv3, virtual router support for unicast, VRRPv6, PIM, MLDv1/v2) are supported via an enhanced feature license.
- Energy Efficient Ethernet (EEE) capability is provided.

What are the primary uplink port capabilities of the Juniper EX3400-24T? +
The EX3400-24T provides versatile connectivity for high-bandwidth uplinks. It features four SFP/SFP+ ports capable of 1G or 10G speeds, plus two dedicated 40G QSFP+ ports. This combination ensures sufficient throughput for aggregating downstream traffic to your core network or connecting to high-speed storage arrays without bottlenecking your access layer.
Does the EX3400-24T support Virtual Chassis technology? +
Yes, the Juniper EX3400-24T fully supports Virtual Chassis technology. This allows you to interconnect up to ten EX3400 switches, managing them as a single logical device. This simplifies administrative overhead while providing built-in redundancy and increased port density across your wiring closet, ensuring consistent network performance as your organizational requirements scale.
How is the thermal management and airflow designed for this switch? +
The EX3400-24T utilizes a robust front-to-back airflow design, which is optimized for standard hot-aisle/cold-aisle data center rack deployments. Equipped with redundant, field-replaceable fans, the chassis maintains consistent operating temperatures even under heavy load. This thermal efficiency is critical for maintaining long-term reliability and component longevity in mission-critical enterprise environments.
Is the Juniper EX3400-24T suitable for Layer 3 routing applications? +
Absolutely. While primarily deployed as a high-performance Layer 2 access switch, the EX3400-24T supports advanced Layer 3 features, including static routing and dynamic protocols like OSPF and RIP. This functionality makes it an excellent choice for branch offices or campus networks that require segmentation and intelligent traffic routing at the edge.
What type of power supply unit is included with the EX3400-24T? +
The unit ships with a single JPSU-150-AC-AFO power supply unit. This specific model is designed for front-to-back airflow to match the chassis cooling profile. For environments requiring power redundancy, the switch features a second, optional power supply slot, allowing you to install an additional PSU for increased uptime and operational resilience.
What operating system manages the EX3400-24T? +
This switch runs on the Junos OS, the same powerful operating system used across the entire Juniper portfolio. By utilizing a unified, modular OS, the EX3400-24T delivers consistent configuration syntax, robust security features, and deep programmability, allowing network administrators to leverage automation scripts and consistent operational workflows throughout the enterprise network architecture.
Can the EX3400-24T handle voice and video traffic effectively? +
The switch is well-equipped for converged networks. It supports comprehensive Quality of Service (QoS) features, allowing you to prioritize voice and video traffic to minimize latency and jitter. With support for IEEE 802.1p and Differentiated Services Code Point (DSCP) tagging, the EX3400-24T ensures that time-sensitive applications receive the necessary bandwidth and priority treatment.
Are the optical transceivers included with the EX3400-24T? +
The EX3400-24T does not include optical transceivers with the base hardware package. All SFP, SFP+, and QSFP+ optics must be purchased separately based on your specific distance and media requirements, such as fiber type or copper DAC lengths. This gives you the flexibility to select the precise optics needed for your unique cabling infrastructure.
How can I obtain a bulk quote for multiple EX3400-24T units? +
