Description

The JPSU-650W-AC-AFI is a 650W AC hot-swappable power supply designed for Juniper EX and QFX series switches, including the EX4550, EX4600, EX4650, QFX5100, and QFX3500. Featuring FRU-side to port-side (back-to-front / AFI) airflow, it is purpose-built for standard data centre hot-aisle/cold-aisle cooling configurations, ensuring compatibility with your existing thermal management architecture. The blue-coloured handle and AFI labelling provide instant visual confirmation of airflow direction to prevent mismatched PSU installations.

As a hot-insertable, hot-removable field-replaceable unit, this power supply can be installed or swapped without powering down the switch — minimising downtime in production environments. When two units are deployed in a supported chassis, the JPSU-650W-AC-AFI supports N+1 or N+N redundancy for maximum availability. Overcurrent protection (OCP) and Junos OS airflow-mismatch alarms add an additional layer of operational safety.

FAQs

Q: Which Juniper switch platforms is the JPSU-650W-AC-AFI compatible with?
A: The JPSU-650W-AC-AFI is compatible with the Juniper EX4550, EX4600, EX4650, QFX5100, and QFX3500 series switches. Always confirm the specific chassis requirements in your Juniper documentation before installation.

Q: What does AFI mean, and why does airflow direction matter?
A: AFI stands for 'Air Flow In' — also described as FRU-side to port-side, or back-to-front airflow. This matches standard data centre hot-aisle/cold-aisle configurations where cool air enters from the rear of the switch. Using a PSU with the wrong airflow direction can disrupt thermal management and trigger a Junos OS alarm.

Q: Can I hot-swap this power supply without taking the switch offline?
A: Yes. The JPSU-650W-AC-AFI is a hot-insertable, hot-removable FRU. You can install or replace it while the switch remains powered on, provided a second PSU is installed and carrying the load, ensuring zero downtime during maintenance.

Q: Does this power supply support redundant operation?
A: Yes. When two JPSU-650W-AC-AFI units are installed in a compatible chassis, the switch supports N+1 or N+N power redundancy, providing failover protection if one PSU fails.

Q: How do I visually identify the airflow direction of this PSU?
A: The JPSU-650W-AC-AFI features a blue-coloured handle and is labelled 'AFI' to clearly indicate the back-to-front (FRU-side to port-side) airflow direction. The opposing AFO (port-to-FRU) variants use a different handle colour for easy differentiation.

Q: Can I purchase the JPSU-650W-AC-AFI in Australia from IP Trading?
A: Yes. IP Trading is an Australian B2B IT hardware reseller supplying Juniper network components including power supplies. Visit iptrading.com.au to check stock, get a quote, or speak with our technical team for compatibility advice.
