Connect wired endpoints at their available access speed while preserving high-speed uplink capacity for the distribution layer. FortiSwitch-348G-FPOE combines 24 x 1GE RJ45 ports with 24 x 2.5GE RJ45 ports, allowing conventional Gigabit clients and newer multi-gigabit devices to coexist on one switch. Four 10GE SFP+ uplinks provide fiber or direct-attach connections to upstream switching infrastructure. The FS-348G-FPOE supports Layer 2/3 switching and FortiGate switch-controller compatibility for deployments that manage switching through the Fortinet security and networking environment. MACsec support adds link-layer traffic protection where encrypted Ethernet connections are required. The mixed 1GE and 2.5GE copper layout makes the model suitable for access layers that are transitioning to higher-speed wired devices without replacing every existing Gigabit endpoint. IEEE 802.3bt PoE support supplies power to connected compatible devices, with a maximum PoE output limit of 1,540 W. That capacity is relevant where the same access switch must support a concentrated set of powered devices alongside standard network clients. The combination of 48 copper access ports, four 10GE SFP+ uplinks, MACsec, and high PoE capacity distinguishes this configuration within the FortiSwitch family.
