Silver rectangular power supply unit with front-to-back airflow vents and 920 W label

HPE Juniper Networking

HPE Juniper Networking JPSU-920-AC-AFO 920 W power supply

SKU CH-AT32-3NS42 MPN JPSU-920-AC-AFO

Delivers 920 W with front-to-back airflow for reliable Juniper switch operation

  • 920 W output supports high-demand network configurations
  • front-to-back airflow design maintains stable operating temperatures
  • hot-swap redundant architecture prevents complete system shutdown
  • engineered for energy efficiency to lower operational costs
  • purpose-built compatibility ensures seamless Juniper device integration

High-output network power supply

The HPE Juniper Networking JPSU-920-AC-AFO delivers 920 W of AC power to compatible Juniper switches. It is built for data-centre and enterprise racks that need redundant, hot-swappable power to keep networking gear running without interruption. The unit targets administrators who require front-to-back airflow to match standard cold-aisle cooling layouts.

Suited for redundant Juniper deployments

This supply fits Juniper chassis that accept the JPSU-920-AC-AFO form factor and need N+1 redundancy for critical links. It is not for builders who need a different airflow direction, a DC input variant, or a lower-wattage unit for smaller access switches. Buyers without a compatible Juniper platform cannot use this module.

Front-to-back airflow and hot-swap design

The front-to-back airflow aligns with typical rack cooling so exhaust heat leaves the rear of the cabinet. Hot-swap capability lets technicians replace a failed unit without powering down the switch, reducing mean-time-to-repair. No additional cables, mounting brackets or management software are bundled with the power supply itself.

Highlights

  • 920 W output supports high-demand network configurations
  • front-to-back airflow design maintains stable operating temperatures
  • hot-swap redundant architecture prevents complete system shutdown
  • engineered for energy efficiency to lower operational costs
  • purpose-built compatibility ensures seamless Juniper device integration

Questions about this item

What Juniper switch chassis accepts the JPSU-920-AC-AFO power supply?

The JPSU-920-AC-AFO is designed for Juniper networking equipment that supports a 920 W front-to-back airflow power supply; check your switch model’s hardware guide to confirm the exact chassis compatibility.

Can I mix this 920 W unit with an older lower-wattage supply in the same chassis?

Juniper chassis that support redundant power supplies generally allow mixed-wattage units; the system will draw from each supply according to its rating, so the 920 W unit will provide up to its full capacity alongside the older supply.

How do I verify the JPSU-920-AC-AFO is operating correctly after installation?

After seating the unit, check the front-panel LEDs — a steady green indicator shows normal output and proper front-to-back airflow, while amber or off signals a fault or missing input power.
