Expert Analysis
These two switches are aimed at different jobs in the campus, and that is the single most important thing to understand before comparing them. The FortiSwitch 524D is a 1G aggregation/distribution box with serious uplink density — 4 × 10GE SFP+ plus 2 × 40GE QSFP+ — and 288 Gbps of fabric. It has no PoE, so it is not a wiring-closet access switch; it is the layer above one. The Catalyst 9300L-48P is the opposite: 48 × 1G PoE+ access ports with only 4 × 1G uplinks, designed to land phones, APs and user endpoints in the closet and stack with peers via StackWise-160.
If you are buying for the wiring closet, the Cisco wins on merit: twice the access ports per RU, a 505 W PoE+ budget, MACsec at line rate, and IOS-XE with mature telemetry (NETCONF/YANG, gNMI, model-driven streaming) plus integration into ISE/TrustSec and Catalyst Center. The trade-off is licensing — Network Essentials gets you switching, but BGP, EVPN and the richer policy features sit behind Network Advantage and a DNA subscription, which materially changes the five-year cost.
If you are buying for distribution or for a Fortinet-led estate, the FortiSwitch 524D is the more rational choice. FortiLink lets a FortiGate manage the switch as a logical extension of the security fabric, which is genuinely useful for UK mid-market sites running Fortinet for SD-WAN and ZTNA already. You also get OSPF and BGP without a subscription tier, and 40GE uplinks that the 9300L-48P simply does not offer on this SKU. The weakness is the access-layer story: no PoE, only 24 copper ports, and a smaller third-party ecosystem than Cisco's.
Recommendation: pick the Catalyst 9300L-48P for PoE access stacks in NHS, education and enterprise sites already standardised on Cisco ISE or Catalyst Center, and budget for DNA licensing up front. Pick the FortiSwitch 524D where it actually belongs — as an aggregation switch above PoE access stacks (FortiSwitch or otherwise), particularly when the network is being managed from a FortiGate and you want 40G uplinks without paying for an advanced licence tier.
