FS-108F-Fortinet Network 8XGE Port, 2X SFP Port, 1X RJ45 Port Switch

Understand the powered-device connection

A power-input port and a power-output port perform different jobs. On FS-108F, copper port 8 supports the powered-device role: an upstream PoE source can energize the switch. Fortinet’s model table assigns this order zero PoE-supplying ports and a zero output budget. Connecting a camera or phone does not cause this switch to power that endpoint. Use an external supply arrangement or select a separately specified PoE-output model when endpoint power is required.

Count eight access interfaces and two optical slots

FS-108F carries seven standard Gigabit RJ45 interfaces plus the Gigabit/PoE-PD RJ45 interface at port 8. These total eight copper data interfaces, followed by SFP connections numbered 9 and 10. Its rear RJ45 console is a CLI management connection rather than a ninth Ethernet port. This distinction is useful when checking a replacement switch against a cabling schedule or an older listing that mixes console and network counts.

Fit the desktop power and installation plan

The base 108F enclosure measures 30 mm high by 120 mm deep by 180 mm wide and uses fanless, side-to-side cooling. Its manufacturer guide describes a 12 V DC adapter or an upstream PoE PSE as alternative power sources. Verify the exact adapter rating and plug supplied with the offered unit; the present datasheet specification and ordering sections differ on adapter amperage, so this page does not assert a rating. The rack-bracket instructions in the family guide apply to the larger PoE/FPOE models and must not be assumed for this base unit.

Map the management path to a documented release

The quick-start guide marks ports 7–10 as FortiLink connections, combining copper and SFP interfaces. FortiSwitchOS 7.4.6 lists FS-108F in its supported models, providing a version-specific reference for planning. Confirm the intended FortiGate controller release, management mode and switch upgrade path against that environment. Software support in one release is not proof of the offered unit’s license transfer or an active support entitlement.
