Proprietary 930 W AC power supply

This Juniper EX-PWR3-930-AC unit delivers 930 W of AC power with PoE+ capability for compatible Juniper EX Series Ethernet switches. It is a proprietary module designed specifically for that switch family rather than a standard ATX component. Network engineers maintaining or expanding those switches are the intended users.

Hot-swap installation in supported chassis

The supply slides into the switch power bay and locks with a latch, allowing replacement without tools while the system remains powered if a second supply is present. The main risk is inserting the module into a non-EX chassis or a bay that lacks PoE+ support, which will prevent the switch from recognising the unit. Verifying the exact switch model against the compatibility list avoids that mismatch.

For Juniper EX Series switch deployments

This supply suits administrators who need redundant or additional PoE+ power for Juniper EX Series switches. It does not fit standard PC cases, servers from other vendors, or any platform outside the stated EX Series compatibility. Buyers requiring a generic ATX power supply or a unit for non-Juniper hardware should look at something else.

Questions about this item

How can I confirm the EX-PWR3-930-AC is delivering 930 W after installation?

Check the switch management interface for power supply status showing the unit online and providing 930 W output to the chassis and PoE+ ports.

What ships with the EX-PWR3-930-AC and what must be sourced separately?

The proprietary power supply module is included; an AC power cord compatible with local mains and the Juniper EX Series switch chassis are required separately.

Which version of the EX-PWR3-930-AC should I select for a PoE+ deployment?

The EX-PWR3-930-AC is a single 930 W AC model with PoE+ capability built in, so no alternative version or capacity choice exists for this part number.
