Juniper Netzteil (intern) - FRU

When a power supply fails in a critical network gateway, downtime is measured in lost revenue and frustrated users. The Juniper JPSU-H-340W-AC eliminates that risk by providing a field-replaceable, hot-swappable power source that keeps your SRX Series services gateway running without interruption. This internal PSU delivers up to 650W of reliable power with 80 PLUS Platinum efficiency, ensuring your network edge remains operational even under heavy load.

Who is it for

Network administrators and IT professionals managing Juniper SRX300, SRX320, SRX340, SRX345, or SRX380 services gateways in enterprise branch offices, retail locations, or remote sites. It is ideal for those who require redundant power configurations to maximize uptime and simplify maintenance.

Main features

• Hot-swappable design: Replace a failed unit without powering down the gateway, minimizing downtime.
• High efficiency: 80 PLUS Platinum certification reduces energy waste and operating costs.
• Wide input range: Accepts 100-240V AC, 50/60 Hz, making it compatible with global power standards.
• Integrated cooling fan: Maintains optimal temperature for reliable performance.
• Comprehensive protection: Over-voltage, over-current, short-circuit, and over-temperature safeguards protect both PSU and gateway.
• Status LED: Provides at-a-glance power and fault indication for quick troubleshooting.
• Redundancy support: Enables dual-PSU configurations for continuous operation.
