EX3400-48T-AFI 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.

48-port 10/100/1000BASE-T, 4 x 1/10GbE SFP/SFP+, 2 x 40GbE QSFP+, redundant fans, back-to-front airflow, 1 AC PSU JPSU-150-AC-AFI included (w/o optics)

Frequently Asked Questions

What is the primary cooling configuration for the Juniper EX3400-48T-AFI? +
The EX3400-48T-AFI model features a back-to-front airflow design. This specific cooling configuration is essential for data center hot-aisle/cold-aisle deployments, ensuring that the switch aligns with the intake and exhaust patterns of server racks to prevent thermal recirculation and maintain optimal operating temperatures under load.
How many ports does the EX3400-48T-AFI provide for network connectivity? +
This unit is equipped with 48 10/100/1000BASE-T ports, providing high-density Gigabit Ethernet connectivity for end-user devices or access-layer deployments. Designed for robust network performance, these ports support copper media, making it an ideal choice for standard enterprise cabling environments where reliable Layer 2 and Layer 3 switching functionality is required.
Is the EX3400-48T-AFI suitable for Layer 3 routing tasks? +
Yes, the EX3400-48T-AFI is a versatile managed switch capable of supporting advanced Layer 3 routing features. It integrates seamlessly into enterprise networks that require static routing, RIP, and OSPF capabilities, allowing IT administrators to manage inter-VLAN traffic and perform efficient packet forwarding directly at the access or distribution layer.
Can I use the EX3400-48T-AFI in a Virtual Chassis configuration? +
The EX3400 series supports Juniper's Virtual Chassis technology, which allows multiple interconnected switches to operate as a single logical device. This significantly simplifies network management and increases availability, enabling administrators to scale their access-layer capacity while maintaining a unified control plane and streamlined configuration management across the entire stack.
Does the EX3400-48T-AFI support modular uplink options? +
This switch supports fixed-configuration uplinks on the front panel, which are designed to provide high-speed connectivity to the distribution or core layers. By utilizing these ports, you can ensure that your access switches have the necessary bandwidth to prevent bottlenecks, maintaining the high performance required for modern bandwidth-intensive enterprise applications.
What type of management software does the EX3400-48T-AFI utilize? +
This switch operates on the industry-standard Juniper Networks Junos OS. This robust operating system provides a consistent and programmable management interface across all Juniper hardware. IT teams benefit from extensive CLI options, SNMP support, and integrated automation tools, ensuring granular control over switch configurations and real-time monitoring of network health.
How should I plan for the installation of an EX3400-48T-AFI in a standard server rack? +
Installation of the EX3400-48T-AFI is straightforward due to its standard 1U rackmount form factor. Given its back-to-front airflow, ensure that your rack placement aligns with the designated cold-aisle intake. Proper planning should involve checking the depth of your cabinet to accommodate the chassis and ensuring adequate power distribution units are available for the switch's power supply.
Is the EX3400-48T-AFI compatible with existing EX3400 stack components? +
The EX3400-48T-AFI is fully compatible with other members of the EX3400 family. When stacking, it is recommended to ensure that all units in the virtual chassis are running compatible versions of the Junos OS. This interoperability allows for seamless integration into existing deployments without the need for additional specialized hardware or complex transition configurations.
