Forwarding Rate: ~260 Mpps (duplex; figure published for the 148F-POE datasheet, consistent with the base model's 176 Gbps capacity but not confirmed for it)
PoE Budget: 0 W (no PoE ports; PoE models are the 148F-POE and 148F-FPOE)
Layer: L2 managed (some resellers describe it as L2+ management)
Stacking Support: No physical stacking confirmed for the base model; managed via FortiLink from a FortiGate (the FPOE datasheet cites up to 300 switches per FortiGate)
Packet Buffer: 2 MB
VLAN Support: 4K
Link Aggregation: 8 ports per LAG, 16 LAGs
ACL Entries: 768
Spanning Tree Instances: 16
Form Factor: 1U rack-mountable
Memory: 512 MB DDR3 DRAM, 64 MB flash
Curation Review
✔ Pros:Full 48-port GbE access with 4x 10GbE SFP+ uplinks for a 1U footprint; 176 Gbps switching capacity is ample for a non-blocking access layer; Managed by FortiGate via FortiLink for centralized policy and config with the Fortinet Security Fabric; Lower entry price than the PoE variants when PoE is not needed; Refurbished units are available at about $712.50 from some resellers
✘ Cons:No PoE, so it cannot power phones, APs or cameras; Listed by at least one distributor (SHI) as end-of-life, so the 100 Series may be superseded; Official Fortinet datasheet not located; several specs come from reseller copies and need verification; Forwarding rate, MAC table size and jumbo frame support are unconfirmed for the base model; Conflicting Layer 2 vs. L2+ classification across sources; Dependent on a FortiGate or FortiLink for full management features
