Description

The JPSU-550-C-DC-AFO2 is a 550W DC power supply for Juniper EX4400 Ethernet switches, built with front-to-back (AFO) airflow and a pigtail DC input for ORv3 tray deployments. It is a hot-swappable, field-replaceable module with its own cooling fan, suited to rack environments that distribute DC power through an ORv3 tray.

Two power supplies can be installed in a single EX4400 chassis to provide 1+1 power redundancy. The module is intended for the EX4400-24T, EX4400-24X, EX4400-48T and EX4400-48F switches. Front-to-back airflow draws cool air in through the front panel and exhausts hot air at the rear, matching hot aisle and cold aisle layouts.

- Hot-swappable, field-replaceable PSU with its own cooling fan
- Supports 1+1 power redundancy with two modules per chassis
- Pigtail DC input suited to ORv3 tray deployments
- Front-to-back airflow for hot aisle and cold aisle rack layouts
