The S8G02GI/GID upgrades every access port to Gigabit, so 4K cameras, multi-sensor panoramic cameras and gigabit wireless APs each get a full-speed connection instead of sharing fast-Ethernet headroom. Two Gigabit RJ45 uplinks keep the NVR feed clean even with all 8 ports pushing high-bitrate streams at once. Built-in IEEE 802.3af/at PoE+ still delivers up to 30W per port for PTZ and IR-illuminated cameras, and the fanless metal case keeps it quiet in a rack, cabinet, or ceiling void. Choose the 96W S8G02GI for typical loads or the 120W S8G02GI, which adds a watchdog auto-reset, for heavier PTZ/IR loads.

|---|---|---|
| S8G02GI | Standard 96 W PoE budget — fits typical fixed cameras, wireless APs and video intercoms. | |
| S8G02GI | High-power 120 W version — for PTZ domes, IR illuminators and other heavy loads. This version also adds a hardware watchdog that auto-resets the switch if it hangs under load. |
One model, two PoE power versions. Both share the same ports, housing and features; the 120 W version raises the total PoE budget and adds a hardware watchdog for heavy loads. State the power version you need when ordering.
