28-Port PoE Ethernet Switch, 24 POE+@300W + 2 Gigabit Uplink + 2 SFP Slot | (YK-S2422GAP）Unmanaged Plug & Play | PoE Auto Recovery | Sturdy Metal | Desktop /Rack Mount | for Security IP Cameras NVR

Features

• 28-Port Full Gigabit PoE+ with SFP Uplink: Offers 24 PoE+ (802.3af/at) Gigabit ports (30W each), 2 Gigabit uplinks, and 2 dedicated SFP fiber slots. Total PoE budget is 300W. SFP port supports fiber runs up to 10km+ for long-distance or industrial networks.
• Smart Power Management & Overload Protection: If total PoE exceeds 300W, the switch cuts power to lowest-priority ports first (port 124). Auto-detects PoE devices, powers only compatible equipment, and protects non-PoE devices. Short-circuited ports shut down independently.
• AI Watchdog for Auto-Fault Recovery: Built-in AI Watchdog monitors PoE IP cameras constantly. If a camera freezes or goes offline, the switch auto-restarts that port no manual reboot. Cuts on-site maintenance and ensures 24/7 surveillance stability.
• One-Button, Two Modes: Extend & VLAN Isolation: Flip the DIP switch to Extend Mode for PoE+ data up to 820ft (250m) per port. Switch to VLAN Mode to isolate ports 1-24 from each other, suppressing network storms and blocking unauthorized device access.
• Safety Built-In: Metal housing delivers superior heat dissipation and long-term reliability. Fanless design provides zero noise ideal for offices or server room. 6kV surge protection guards against lightning strikes for indoor/outdoor use.
• True Plug-and-Play with LED Indicators: No configuration needed just connect PoE cameras, APs, or VoIP phones and power on. LED indicators show real-time power, PoE supply, link status, and active mode. Wall-mountable design fits any network closet or security rack.
