OVERVIEW

What the FortiSwitch AX9000G 3000 W AC Power Supply is for

The FS-AX9000G-PS-3KAC is the AC power supply for the FortiSwitch AX9000G chassis family. It delivers 3,000 W on a 200–240 V feed and 1,400 W on 100–120 V — a difference worth planning for, because a chassis fed at 120 V needs more than twice as many supplies to reach the same budget.

A chassis accepts up to eight hot-swappable power supplies, AC or DC. How many you actually need depends on the installed supervisor modules and line cards: an AX9004G draws up to 12.8 kW on a 100–120 V AC feed and up to 26.2 kW on 200–240 V at maximum configuration, and a fully populated PoE chassis is at the top of that range because each LC10P card carries a 4,320 W PoE budget of its own.

The same unit fits both the four-slot FS-AX9004G and the eight-slot FS-AX9008G. If you need DC, the FS-AX9000G-PS-2K5DC supplies 2,500 W from a −48 to −60 V feed. Power supplies are hot swappable, so a failed unit can be replaced with the chassis in service.

FAQ

FortiSwitch AX9000G 3000 W AC Power Supply frequently asked questions

3,000 W on a 200–240 V AC feed, but only 1,400 W on 100–120 V. That is a significant difference: a chassis fed at 120 V needs more than twice as many supplies to reach the same total budget, so the feed voltage should be settled before you decide how many to order.

It takes up to eight, and the number you need depends on the installed supervisor modules and line cards. An AX9004G draws up to 12.8 kW on a 100–120 V feed and up to 26.2 kW on 200–240 V at maximum configuration. A chassis full of LC10P PoE cards sits at the top of that range, because each card carries its own 4,320 W PoE budget. Send us your configuration and we will work out the supply count.

Yes. The same FS-AX9000G-PS-3KAC is used in the four-slot FS-AX9004G and the eight-slot FS-AX9008G. Unlike the fan modules, which are chassis specific, power supplies are shared across the family.

Yes. The FS-AX9000G-PS-2K5DC delivers 2,500 W from a −48 to −60 V DC feed. A chassis accepts up to eight supplies, AC or DC.

No, the power cord is not included with the supply. Tell us your region and rack PDU type when you order and we will make sure the right cords are quoted alongside.
