FIM-7941F is the starting I/O module in Fortinet's FG-7081F-2, FG-7081F-2-DC and FG-7121F-2 ordering rows. The cited table does not label the module “high-density,” so that unsupported marketing descriptor is removed from this page.
The optional-module row identifies a hot-swappable, NP7-accelerated device with two QSFP-DD, twenty QSFP28 and two SFP28 ports, two GE RJ-45 management interfaces and two 4 TB local log-storage devices.
Although the brief port list matches the public FIM-7921F description, the manufacturer assigns FIM-7941F to different starting chassis rows. Procurement must verify the exact system BOM, supported slot, FortiOS version, hardware revision, transceivers and entitlement rather than swapping the modules by port count alone.
No chassis, FPM, PSU, optical module or cable is asserted as part of this standalone I/O-module PID. Request serial-level or BOM-level confirmation for the offered unit.
