Redundant 850 W AC power module

This Juniper Networks plug-in module delivers 850 W of AC power with front-to-back airflow. It is built for QFX5100-96S Ethernet switches and ACX5400 series routers. The unit operates as a hot-pluggable field-replaceable unit in redundant configurations. Data-centre deployments can swap modules without powering down the chassis.

Compatibility and power-source check

Verify that the target switch or router model accepts this specific part number and front-to-back airflow direction. Confirm the site provides AC mains between 110 and 240 volts for the module’s input range. Ensure the chassis has an available power-supply slot and that the existing cooling design matches the airflow orientation.

Suited for Juniper QFX

Network engineers expanding or maintaining QFX5100-96S switches or ACX5448-D and ACX5448-M routers will find a direct fit. Buyers who need a different wattage, rear-to-front airflow, or DC input should look at other modules. The unit does not support platforms outside the listed Juniper families.

Questions about this item

What comes with the JPSU-850W-AC-AFO and what must I order separately?

The unit is a hot-pluggable redundant power supply module designed for Juniper ACX5400 routers and QFX5100-96S switches. Mounting hardware and power cables are not included and must be sourced separately.

How do I decide between the 650 W and 850 W power supply for my ACX5448 router?

The standard ACX5448 runs at 650 W, while the ACX5448-D and ACX5448-M models require 850 W. Match the supply to the exact router variant you are deploying.

What does the 850 W rating mean when the module is installed in a QFX5100-96S switch?

It delivers up to 850 watts of AC power with front-to-back airflow, accepting 110 to 240 V input, and operates as a redundant, hot-swappable module without powering down the switch.
