Accessories in production need fast replacement paths — and the Juniper EX-PWR-190-DC delivers exactly that. This 190W DC power supply is purpose-built for Juniper EX Series Ethernet Switches, offering hot-swap capability so your network operations team can replace failed units without downtime. Manufactured by Juniper Networks and carrying part number EX-PWR-190-DC (REV-A), this internal chassis-mounted PSU accepts nominal −48V DC input across a wide operating range of −40V DC to −72V DC, making it suitable for telecom and data center environments that rely on distributed DC power architectures.

The EX-PWR-190-DC integrates seamlessly with Juniper's EX Series management subsystem, providing real-time chassis environmental and power monitoring so you maintain visibility over PSU health and performance. Front-to-back airflow design ensures efficient thermal management across operating temperatures from 0°C to 45°C, while robust design supports storage conditions from −40°C to 70°C. Compliance with NEBS-compatible and ETSI-aligned standards positions this supply for carrier-grade and regulated deployments. Network engineers and IT procurement teams standardizing on Juniper platforms will find the DC terminal block connector and proven Juniper form factor reduce integration complexity and spare-parts overhead.

Enterprise Deployment Scenarios

• Telecom central offices and remote terminals powered by −48V DC distribution networks requiring hot-swappable PSU redundancy
• Carrier-grade data centers needing NEBS-compatible power infrastructure for mission-critical switching fabric
• Branch and edge deployments where distributed DC power systems eliminate the need for AC-to-DC conversion at the switch
• High-availability network clusters where hot-swap PSU capability minimizes planned and unplanned maintenance windows
• ETSI-aligned environments in Europe and beyond requiring standards-certified power supply components
