HPE 5710 250W FB AC Power Supply Unit

The HPE JL589A is a power supply that delivers 250 watts of AC power to HPE FlexFabric 5710 switches, keeping critical network links stable and efficient.

It follows the same front to back airflow pattern as the switch, so heat exits in a controlled path and rack temperature stays predictable. Because the module installs through a simple plug-in slot, a technician can add or replace it without disturbing the rest of the chassis or nearby equipment.

The housing measures 5.1 by 6.4 by 30.5 centimeters, and it weighs about 680 grams. This compact footprint and light weight make handling straightforward, even inside dense racks or narrow cable routes. Once seated, the latch secures the unit, giving you a reliable connection that will not work loose during maintenance.

Network administrators who run enterprise cores, branch offices, or test labs can keep one or more of these power supplies on hand as part of a proactive redundancy plan. In the event of a failure, swapping the module takes only moments and restores full power capacity to the switch.

HPE backs the JL589A with a one-year warranty, so you have direct support if any issue arises.
