High-Performance Gigabit Switching with 288 Gbps Capacity

The Juniper EX3400-24P provides wire-speed performance with a switching capacity of 288 Gbps, ensuring consistent throughput even under heavy network loads. It supports a MAC address table of up to 32,000 entries, allowing scalable deployments in medium to large enterprise networks.

This makes it ideal for:

• Corporate office networks

• Campus access layer deployments

• Education environments

• Healthcare facilities

• Retail and hospitality networks

The high switching capacity ensures reliable connectivity for high-bandwidth applications such as video conferencing, VoIP systems, cloud services, and real-time collaboration tools.

24 Gigabit Ethernet Ports with PoE+ Support

The EX3400-24P features:

• 24 × 10/100/1000BASE-T Gigabit Ethernet RJ-45 ports

• Support for IEEE 802.3af PoE

• Support for IEEE 802.3at PoE+

PoE capability allows the switch to power devices directly over Ethernet, including:

• IP telephones

• Wireless access points

• IP security cameras

• Video conferencing endpoints

• Building automation devices

This eliminates the need for separate power supplies and simplifies enterprise network installations.

Flexible Uplink Connectivity

The EX3400-24P supports high-speed uplinks for aggregation and core connectivity. It includes:

• Four dual-mode SFP/SFP+ uplink ports (1GbE/10GbE)

• Two 40GbE QSFP+ uplink ports

This flexibility allows organizations to scale their network architecture efficiently, whether connecting to aggregation switches, data center cores, or stacking multiple access switches.

Virtual Chassis Technology for Simplified Management

Juniper’s Virtual Chassis technology allows up to 10 EX Series switches to be interconnected and managed as a single logical device. This reduces operational complexity and simplifies configuration across multiple access switches.

Benefits include:

• Centralized management

• Reduced operational costs

• Simplified network expansion

• Single control plane management

Virtual Chassis is especially valuable in multi-floor buildings and campus networks.

Junos Fusion Enterprise Integration

The EX3400 can operate as a satellite device in a Junos Fusion Enterprise deployment, enabling centralized management of large numbers of access switches through a single logical platform. This architecture is designed to reduce configuration overhead and improve operational efficiency in enterprise-scale environments.

Advanced Quality of Service (QoS)

The switch provides eight QoS queues per port, ensuring proper prioritization of network traffic. This guarantees optimal performance for:

• Voice traffic (VoIP)

• Video streaming and conferencing

• Data applications

• Security systems

• Building automation networks

Traffic prioritization ensures mission-critical applications remain stable even during peak usage periods.

Carrier-Class Reliability with Junos OS

The EX3400-24P runs on Juniper Junos OS, a field-proven operating system known for stability, security, and automation capabilities. Junos OS provides consistent management across Juniper platforms and ensures enterprise-grade reliability for mission-critical deployments.

Key advantages include:

• Unified management tools

• Automated configuration capabilities

• Strong security policies

• High system stability

Networking Standards Support

The switch supports multiple IEEE networking standards including:

• IEEE 802.1D

• IEEE 802.1Q

• IEEE 802.1ab

• IEEE 802.1ad

• IEEE 802.1p

• IEEE 802.1s

• IEEE 802.1w

This ensures interoperability within modern enterprise networks.
