🔌 Product Type Summary
Unmanaged L2 Industrial PoE Switch – 8 Port
| Feature | Details |
|---|---|
| Ports | 8 × Gigabit RJ45 PoE ports |
| Uplinks | 2 × Gigabit SFP (fiber) ports |
| PoE Standards | IEEE 802.3af (15.4 W), 802.3at (30 W), 802.3bt (up to 90 W) |
| Hi-PoE | Ports 1 & 2 support up to 90 W (802.3bt, great for PTZs) |
| PoE Power Budget | 110 W total |
| Long-Range PoE | Ports 7 & 8 support up to 300 m (likely 10 Mbps) |
| Surge Protection | 6 kV surge protection on all PoE ports |
| DIN Rail | Supported – industrial mounting standard |
| Operating Temp | –30°C to +65°C |
| Power Supply | Included by default – compatible with ELG-150-48A (48V industrial PSU) |
💡 Core Functional Highlights
| Function | Description |
|---|---|
| PoE Watchdog | Automatically resets unresponsive PoE devices (IP cams, APs) |
| Port Isolation | Prevents direct communication between specific ports – ideal for CCTV |
| Extended PoE Distance | Ports 7–8 support long-distance PoE up to 300 m with proper cabling (reduced speed) |
| Rugged Build | Withstands harsh environments — industrial design, wide temp range |
| Fiber Uplinks | 2 × SFP ports offer flexible and high-speed backhaul (fiber modules needed) |
🔋 PoE Power Budget Breakdown
Total 110 W available:
-
If you use both Hi-PoE ports (90W + 90W), you exceed the budget — so only one Hi-PoE (90W) device at a time.
-
Example usage scenarios:
-
1 × 90W PTZ cam + 2 × 10W regular cams
-
3–5 × 15–30W devices depending on power mix
-
💡 Tip: Keep total PoE draw ≤ 110W to avoid drops or shutdowns.
🛠️ Use Cases
✅ Ideal for:
-
Remote security camera hubs, especially Hi-PoE PTZs
-
Industrial automation, roadside or outdoor deployments
-
Edge devices needing fiber uplink + extended PoE range
🚫 Not ideal for:
-
Networks requiring VLAN, QoS, IGMP snooping, or remote management (this is unmanaged)
🔌 Power Supply Notes
-
ELG-150-48A (by Mean Well):
-
Output: 48 V, 150 W
-
Industrial-grade, supports DIN rail
-
Used when extra power stability or replacements are needed
-
The default PSU may be bundled inside the switch housing or included externally—verify with your vendor if you’ll need to purchase the ELG-150-48A separately or not.
