Questions buyers ask about this part
Is EX-PWR3-930-AC genuine and is the warranty intact?
Yes, new and sealed, with the Juniper warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will EX-PWR3-930-AC work in my server?
Send the server model and the part number of the supply already fitted. In a redundant pair both units have to match on wattage and efficiency grade, or the chassis alerts on every boot.
Do you accept purchase orders and quote at volume?
Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
An accelerated node draws far more than a general-purpose server, so power is sized with the build rather than assumed from the chassis.
