Hot-swap module for Juniper EX3400-48P

This 920 W AC power supply slides into the rear of a Juniper EX3400-48P Gigabit Ethernet switch. It delivers the rated output needed for 48 PoE+ ports and the switching fabric. The unit is new and has been tested working before shipment.

Sustained load behaviour

Designed for continuous operation in a network closet, the module maintains its 920 W rating without thermal throttling under full PoE load. Hot-swap capability lets you replace a failed unit without powering down the switch. No external cables are required beyond the AC inlet.

Questions about this item

How loud does the 920W module run when the EX3400-48P is under full load all day?

The supply is tested working and built to Juniper's original thermal spec, so fan noise stays within the switch's normal operating envelope during continuous 920W delivery.

Does the JPSU-920-AC-AFO need any extra cables or brackets to fit my EX3400-48P?

No, it slides straight into the switch's native power-supply bay and uses the chassis' built-in AC inlet; no additional cables or mounting hardware are required.
