6-Port PoE Switch with Reliable Power Delivery:This switch features 4 PoE-enabled ports (10/100/1000Mbps) and 2 Gigabit Ethernet uplink ports (10/100/1000Mbps). Compliant with IEEE 802.3af/at standards, it delivers up to 30W per PoE port with a total power budget of 65W, capable of powering 4 PoE devices simultaneously.
Priority Power Management: Incorporates an intelligent power allocation system that automatically disables lower-priority ports when total power exceeds 65W, ensuring continuous operation for critical devices while preventing system overload.
VLAN Port Isolation: Supports physical port isolation to enhance LAN security and ensure secure data transmission.
Watchdog Protection: Continuously monitors switch status and performs automatic reboots upon detecting abnormalities to maintain network stability and reliability.
Auto PD Detection: Intelligently identifies connected PoE devices (PDs) and only supplies power to IEEE-compliant terminals, preventing potential damage to non-PoE equipment.
Plug-and-Play Unmanaged Switch: Requires zero configuration - simply connect via Ethernet cable. Supports both desktop and wall-mount installation for flexible deployment.
250m Extended Reach Technology: 3~4 Ports PoE can extend the maximum transmission distance for both power and data from 100m to 250m, significantly reducing cabling challenges and installation costs.
Industrial-Grade Protection: 6KV surge protection (ports/power supply),Fanless thermal design for silent operation
