Frequently Asked Questions
What are the primary uplink port capabilities of the Juniper EX3400-48P? +
The EX3400-48P provides versatile connectivity options for high-bandwidth uplinks. It features four 1/10GbE SFP/SFP+ ports and two 40GbE QSFP+ ports. These high-speed interfaces allow for flexible network design, enabling you to aggregate traffic efficiently into the core layer or establish high-speed stacking configurations without consuming your standard access ports.
How much PoE power budget does the EX3400-48P support with the included power supply? +
The EX3400-48P comes equipped with one JPSU-920-AC-AFO power supply unit. This configuration supports full IEEE 802.3at PoE+ standards across all 48 ports, providing sufficient power for high-demand devices like advanced IP cameras, wireless access points, and VoIP phones. Please ensure your specific device power requirements align with the total power budget provided by this 920W AC power supply.
Does the EX3400-48P support Virtual Chassis technology? +
Yes, the EX3400-48P supports Juniper’s Virtual Chassis technology. This allows you to interconnect multiple EX3400 switches to operate as a single logical device, simplifying management and increasing redundancy. By utilizing the 40GbE QSFP+ ports, you can achieve high-speed backplane throughput, making it an ideal solution for scaling your access layer as your infrastructure grows.
What is the airflow direction of the EX3400-48P and how does it affect rack installation? +
The EX3400-48P utilizes front-to-back airflow, which is critical for deployments in standard data center hot/cold aisle environments. This design ensures that the switch draws cooler air from the front and exhausts it out the rear, preventing heat recirculation. It is recommended to install this switch in racks equipped with proper cable management and thermal containment to maintain optimal hardware longevity.
Are optics included with the EX3400-48P purchase? +
The EX3400-48P unit includes the chassis, power supply, and rack-mount hardware; however, transceiver modules and fiber-optic cables are sold separately. You must source compatible SFP, SFP+, or QSFP+ optics based on your specific link distance and medium requirements to utilize the uplink ports effectively. We recommend verifying compatibility with Juniper-certified transceivers for guaranteed link stability.
What management features does the EX3400-48P offer for network administrators? +
This managed switch supports the powerful Junos OS, providing a consistent CLI for advanced configuration and troubleshooting. It also offers comprehensive management via a web-based interface and SNMP support. These tools allow for granular control over VLANs, security policies, and QoS, ensuring the switch can be easily integrated into existing enterprise management frameworks and monitored for performance metrics.
Is the power supply unit on the EX3400-48P modular? +
The EX3400-48P features a field-replaceable power supply design. The included JPSU-920-AC-AFO is hot-swappable, which is essential for maintaining uptime during hardware maintenance. Additionally, the unit includes redundant fans to further enhance system reliability. This modular approach allows for easier upkeep and ensures that your network access remains highly available in demanding enterprise environments.
Can the EX3400-48P handle Layer 3 routing protocols? +
Yes, the EX3400-48P is a capable Layer 3 switch that supports advanced routing protocols, including OSPF, BGP, and RIP. It is designed to handle static and dynamic routing at the access or distribution layer. By offloading these tasks from the core, you can segment your network traffic more effectively and improve overall routing performance across your corporate branch or campus environment.
