Description

The JPSU-650W-DC-AFI is a 650W DC hot-swappable power supply unit designed for Juniper EX and QFX Series switches, including the EX4550, EX4600, EX4650, QFX3500, QFX3600, QFX5100, and MX204. Featuring FRU-side to port-side (back-to-front / AFI) airflow, this field-replaceable unit aligns with front-to-back chassis cooling architectures common in data centre and enterprise deployments. It accepts –38V to –60V DC input and supports fully redundant, N+1 load-sharing operation for maximum uptime.

The unit is hot-insertable and hot-removable, meaning it can be swapped without powering down the switch — a critical capability for always-on environments. Its blue-coloured handle clearly identifies AFI airflow direction, reducing installation errors. Dual-feed DC input terminals (V+/V+, V-/V-) provide additional power resiliency, and voltage, fan speed, and temperature can be monitored via Junos OS CLI or Juniper Network Director.

Features

- Hot-insertable and hot-removable FRU — replace without powering off the switch
- N+1 redundant and load-sharing when paired with a second PSU in the same chassis
- FRU-side to port-side (AFI / back-to-front) airflow for data centre thermal alignment
- Blue handle for instant visual identification of AFI airflow direction
- Dual-feed DC input terminals (V+/V+, V-/V-) for enhanced power resiliency
- Internal variable-speed fan with dedicated PSU-level cooling
- Full monitoring support via Junos OS CLI and Juniper Network Director (voltage, power, fan speed, temperature)

Warranty

FAQs

Q: What is the airflow direction of the JPSU-650W-DC-AFI, and why does it matter?
A: The JPSU-650W-DC-AFI uses FRU-side to port-side (AFI / back-to-front / Air In) airflow. This means air enters from the rear (FRU/power supply side) and exits from the front (port side). Matching the PSU airflow to your chassis and rack cooling direction is critical to avoid hot spots and maintain reliable operation. The blue handle clearly identifies this as an AFI unit.

Q: Which Juniper switches is the JPSU-650W-DC-AFI compatible with?
A: The JPSU-650W-DC-AFI is compatible with the Juniper EX4550, EX4600, EX4650, QFX3500, QFX3600, QFX5100, and MX204 platforms. Always verify compatibility with your specific chassis revision before ordering.

Q: Can the JPSU-650W-DC-AFI be swapped without shutting down the switch?
A: Yes. The JPSU-650W-DC-AFI is fully hot-swappable, meaning it can be inserted or removed while the switch remains powered on and in service — provided a second PSU is installed and carrying the load. This minimises disruption in production environments.

Q: Does this power supply support redundant operation?
A: Yes. When paired with a second compatible PSU in the same chassis, the JPSU-650W-DC-AFI operates in N+1 redundant, load-sharing mode. If one PSU fails, the other takes over seamlessly without interrupting switch operation.

Q: What is the difference between AFI and AFO airflow, and how do I choose?
A: AFI (Air In) means airflow goes from the FRU/rear side to the port/front side (back-to-front). AFO (Air Out) is the opposite — front-to-back. Your choice must match the airflow direction of your switch chassis and rack cooling layout. Mixing AFI and AFO PSUs in the same chassis is not supported.

Q: Can I purchase the JPSU-650W-DC-AFI from IP Trading in Australia?
A: Yes. IP Trading (iptrading.com.au) stocks authentic Juniper hardware and ships across Australia. Contact us for pricing, availability, and volume enquiries on the JPSU-650W-DC-AFI and other Juniper switch accessories.
