FortiSwitch 424E managed access switch

The FortiSwitch 424E is a rackmount managed switch that delivers 24 Gigabit RJ45 ports and four 10 Gigabit SFP+ uplinks compatible with 1 Gb SFP modules. It operates at Layer 2 and Layer 3, supporting dynamic routing protocols such as OSPFv2, RIPv2, VRRP, BGP and IS-IS. The unit is designed for integration with FortiGate controllers, providing a unified management plane for network security and switching. Small to mid-size enterprises building a scalable, controller-managed fabric will find the feature set aligned with that requirement.

Sustained forwarding with shared buffers

The switch forwards packets at a rate of 190 Mpps while using a dynamically shared 2 MB packet buffer to absorb bursts without head-of-line blocking. Quality-of-service mechanisms include IEEE 802.1p and IP TOS/DSCP priority queuing, explicit congestion notification, egress priority tagging and percentage rate control. IEEE 1588 PTP transparent and boundary clock modes keep timing precise across long-haul links. Average power draw is 22.3 W with a maximum of 23.6 W, so thermal output remains predictable during continuous operation.

Verify uplinks, stacking and controller plans

Confirm that your SFP+ transceivers match the 10 Gb or 1 Gb modes the uplinks support and that cabling distances suit the chosen optics. Stacking is available, so decide whether you will link multiple units into a single logical switch before racking. FortiGate compatibility is a core feature; if you manage switches through a different platform, the integrated benefits will not apply. The chassis measures 44 x 260 x 440 mm and weighs 3.1 kg, so ensure the rack space and mounting hardware accommodate those dimensions.

Questions about this item

How much power does the FS-424E draw when it runs 24/7?

Average consumption is 22.3 W and the maximum is 23.6 W on a 100–240 V AC supply.

Which transceivers do I need for the four uplinks?

The 10 GE SFP+ ports accept 10 GE SFP+ modules and are also compatible with 1 GE SFP modules.

Will my older 1 Gb devices work on the 10 GE SFP+ ports?

Yes, the SFP+ uplinks support 1 GE SFP modules so legacy gigabit links can connect directly.
