Fuente de alimentación AC de 150W para Juniper Networks EX4100 y EX3400, flujo de aire de delante hacia atrás (cable de alimentación no incluido)

Network administrators managing Juniper EX3400 or EX4100 series switches in enterprise wiring closets or data center racks often need a reliable, hot-swappable power supply to ensure uninterrupted operation. The Juniper Networks JPSU-150-AC-AFO delivers 150 watts of AC power with front-to-back airflow, perfectly matching the cooling design of these switch models. This modular unit slides into the switch chassis, providing redundant power when a second supply is installed. The integrated fan maintains optimal thermal performance, while the LED indicators give at-a-glance status for power and faults. Note that the AC power cord is not included and must be ordered separately; the unit features an IEC 60320 C14 inlet for a standard cord. With a mean time between failures exceeding 500,000 hours and compliance with major safety standards, this power supply is built for demanding environments.

Why choose it

This genuine Juniper power supply ensures full compatibility and reliable performance for your EX3400 or EX4100 switches. The front-to-back airflow aligns with the switch's cooling architecture, preventing overheating and extending equipment life. Hot-swap capability allows you to replace or add a power supply without shutting down the network, minimizing downtime. Redundancy support means you can install two units for failover protection, critical for high-availability environments. The high MTBF and broad safety certifications attest to its durability and safety.

Ideal use cases

• Enterprise network closets and data centers deploying Juniper EX3400/EX4100 switches.
• Organizations requiring redundant power for mission-critical network operations.
• IT teams needing a spare power supply for quick replacement and minimal downtime.
• Network upgrades where additional power capacity is needed for PoE devices (with appropriate switch model).

Good to know

The power cord is not included; you will need a standard IEC C13 to C14 power cord appropriate for your region. The power supply is designed for internal use only and should be installed by qualified personnel. It operates efficiently across a wide input voltage range, making it suitable for international deployments. Always verify switch compatibility before installation.
