The FS-AX9000G-LC100 is the 100 gigabit line card for the FortiSwitch AX9000G chassis family. Thirty-two QSFP28 ports run at 100 or 40 GE, with 82 MB of packet buffers behind them. Four of these cards in an FS-AX9004G give 128 ports of 100 GE from a single 11RU chassis.
This is the configuration Fortinet uses for the family's headline performance numbers: 12.8 Tbps of duplex switching capacity and 5,253 Mpps of forwarding, measured with one supervisor module and four LC100 cards. Latency across the chassis is under 4.3 microseconds.
The card is data only, with no Power over Ethernet, and is hot swappable. It fits both the four-slot FS-AX9004G and the eight-slot FS-AX9008G and occupies one line-card slot. For 400 GE, the LC400 card provides eight QSFP-DD ports.

The other parts you need to put this component into service.
A line card does not work on its own. It needs an AX9000G chassis with a supervisor module, fan modules and power supplies. The optics and cables below match this card's ports.
One hundred and twenty-eight. Four LC100 cards in a four-slot FS-AX9004G give 32 QSFP28 ports each. The eight-slot FS-AX9008G takes eight line cards.
Yes. Fortinet measures the family’s 12.8 Tbps duplex switching capacity and 5,253 Mpps forwarding rate with one supervisor module and four LC100 cards installed. The 25.6 Tbps active-active figure is listed as planned firmware, not something available today.
Yes. The 32 QSFP28 ports accept 100 GE QSFP28 or 40 GE QSFP+ optics, so existing 40 GE links can terminate on the same card as new 100 GE ones.
Yes. A line card does not work on its own — it needs an AX9004G or AX9008G chassis with at least one FS-AX9000G-SUP supervisor module, fan modules and power supplies. Ask us to quote the complete system if you are building a chassis from scratch.
No. The AX9000G family is managed through FortiSwitchNMS. Fortinet has stated that Security Fabric integration through FortiLink is planned for this platform, but it is not available today.
