Compact 550 W server power supply

The HPE Juniper Networking JPSU-550-C-AC-AFI is a compact AC power supply rated at 550 W. It is built for Juniper EX4400 switches that require back-to-front airflow. The unit ships without a power cord, which must be sourced separately. This supply suits network administrators deploying or maintaining compatible switching hardware.

550 W output with back-to-front airflow

At 550 W the unit delivers enough headroom for a fully populated EX4400 chassis under typical load. The back-to-front airflow direction matches the switch thermal design so exhaust leaves the rear of the rack. Running multiple high-density line cards or PoE budgets beyond the rated output will exceed the available capacity. No redundant module is included in this single supply.

EX4400 compatibility and airflow direction

The decisive specification is that this power supply is qualified for the EX4400 platform with back-to-front airflow. A front-to-back chassis or a different switch series will not accept this module mechanically or thermally. Verify the switch model and airflow requirement before ordering because no adapter or conversion kit exists.

Domande su questo articolo

Will this JPSU-550-C-AC-AFI unit fit my existing EX4400 chassis?

Yes, the supply is built for the EX4400 platform and uses the compact form factor that slots directly into that chassis.

How can I confirm the 550 W supply is operating correctly once installed?

The EX4400 management interface reports power-supply status, input voltage and output load so you can verify normal operation.

Does the box include a power cord or must I order one separately?

The power cord is not included and must be ordered separately; the box contains only the compact 550 W supply unit itself.
