End-of-sale 48-port Gigabit aggregation switch (48x GE RJ45 + 4x 10GE SFP+ + 2x 40GE QSFP+, data only, 336 Gbps switching, FortiLink-managed). The FS-548D hardware is no longer stocked - the current, in-stock replacement is the FortiSwitch 648F. See the upgrade path below.


The FortiSwitch 548D is a 48-port Gigabit Ethernet aggregation switch from Fortinet's 500-series Campus line - 48x GE RJ45 ports plus four 10GE SFP+ and two 40GE QSFP+ high-speed uplinks, data only (no PoE), with 336 Gbps of switching capacity in a 1RU chassis. Managed over FortiLink from any FortiGate, it folds wired access and aggregation into the Security Fabric so switching, Wi-Fi and security share one console.
The 548D has reached end of sale and is no longer stocked as new hardware. The current, in-stock replacement is the FortiSwitch 648F - the same high-density 48-port role with greater switching capacity and 25 GbE SFP28 uplinks. If you need Power over Ethernet, choose the 648F-FPOE (48 ports, 1800 W); the 548D-FPOE remains available on the mature 500-series platform. See the upgrade path below, or contact us for migration help.

Download the full datasheetThe 548D line shared the same 48-port / 336 Gbps platform with 10GE SFP+ and 40GE QSFP+ uplinks. The base 548D is data only and now end of sale; the 548D-FPOE powered all 48 ports (up to 1440 W). The current-generation equivalents are the FortiSwitch 648F and 648F-FPOE.

The 548D is end of sale. The FortiSwitch 648F is the direct, currently-shipping replacement – same high-density 48-port aggregation role, greater switching capacity and 25 GbE SFP28 uplinks. Choose the 648F-FPOE if you need Power over Ethernet. Same FortiSwitchOS and FortiLink management across the range.
10GE SFP+ and 40GE QSFP+ uplink transceivers for the fiber ports. The same optics carry over to the current FortiSwitch 648F.
No. The FortiSwitch 548D (FS-548D) has reached end of sale and is no longer stocked as new hardware. The current, in-stock replacement is the FortiSwitch 648F – we can quote it and help you migrate.
The FortiSwitch 648F is the direct replacement – the same high-density 48-port aggregation role with greater switching capacity and 25 GbE SFP28 uplinks. For Power over Ethernet, choose the 648F-FPOE (48 ports, 1800 W).
No – the base 548D is data only (48x GE RJ45 + 4x 10GE SFP+ + 2x 40GE QSFP+). The 548D-FPOE powered all 48 ports (750 W, or 1440 W with dual PSU) and is still available on the 500-series platform; the current-gen PoE equivalent is the 648F-FPOE.
Over FortiLink from any FortiGate firewall, so switching, Wi-Fi and security were managed in one console with no separate controller. It could also run standalone. The 648F keeps the same FortiLink management.
Yes. As a Fortinet Select Partner we can spec the right current FortiSwitch, match port, uplink and PoE counts, and quote hardware plus FortiCare. Hardware ships free and fast; licensing is delivered electronically worldwide.
