About the JPSU-650-AC-AFI
The Juniper JPSU-650-AC-AFI power supply delivers 650 Watts of continuous AC power for high density data center switches. Designed for port-to-FRU cooling environments, it draws intake air from the switch front faceplate and exhausts heat out the rear power supply chassis, supporting dense top-of-rack rack deployments.
Compatibility
Compatible with Juniper QFX5100, QFX5110, and QFX5200 series switches. It supports hot-plug installation and dual redundant operation, allowing system administrators to maintain continuous uptime during power maintenance or power source outages in enterprise data centers.
How to identify a genuine unit
Housed in a compact steel module enclosure with an integrated extraction handle, rear exhaust fan, standard IEC C14 connector socket, and diagnostic LEDs. The label lists model number JPSU-650-AC-AFI, assembly number 740-052496, and electrical ratings.
Buying used
Inspect the rear connector contacts for physical wear and check that the extraction latch engages smoothly. Install in a test switch to confirm that the fan operates without abnormal acoustic noise and verify that Junos OS registers the power supply as online and healthy.
