JPSU-650W-DC-AFO, Juniper JPSU Power Supply, 650W DC/Port to FRU airflow/Juniper accessory

The Juniper JPSU-650W-DC-AFO is a carrier‑grade DC power supply accessory designed for Juniper routing and switching platforms in demanding enterprise and service provider networks. It delivers 650W power output with high-efficiency operation, making it suitable for dense PoP deployments, core network nodes, and aggregation sites across Asia, Europe, Africa, and North America. With its DC input design, this module fits sites that rely on -48V DC power systems, such as telecom rooms and data centers. The airflow direction from port side to FRU side supports front-to-back cooling layouts that are common in modern racks, helping maintain stable thermal performance in constrained spaces.

The JPSU-650W-DC-AFO is hot swappable, so integrators and operators can replace or add power capacity without shutting down the host device. This reduces planned downtime and simplifies maintenance for distributors and small system integrators managing remote customer sites. The unit uses active cooling technology to keep internal components within safe temperature limits, supported by an operating range of 0 °C to 40 °C (32 °F to 104 °F). Status and alert LED indicators on the module give clear visual feedback during installation and troubleshooting, which is useful for field engineers and on-site technicians.

Designed with durable, long-lasting materials, the JPSU-650W-DC-AFO offers high reliability and a strong MTBF profile, helping to keep critical services online and limiting truck rolls. The secure connectivity to the host Juniper device ensures stable power delivery and reduces the risk of accidental disconnection during servicing. It is built to meet applicable global standards, with CE, FCC, and other relevant approvals, and is RoHS compliant to support environmental requirements for projects in different regions. Dimensions are tailored for specific Juniper Networks devices, so it integrates cleanly into existing chassis without mechanical modification.

This DC power supply is a practical choice for distributors who need a consistent, globally deployable spare, for small and midsize integrators who build resilient power designs with redundant modules, and for end users who want predictable, stable power in mission-critical environments. Deployed as a single or redundant unit, the Juniper JPSU-650W-DC-AFO helps protect routers and switches against power instability, supports continuous operation in high-density racks, and provides a reliable foundation for IP services, cloud access, and enterprise connectivity.
