Professional High Power 28-Port Gigabit Easy Smart Switch with 24-Port PoE+
– Easy to Use, Multi-Purpose PoE Switch with Powerful Performance

Multiple Application Scenarios
– The TL-SG1428PE is fully compatible with PoE devices, such as IP cameras, access points, and IP phones. It also works with non-PoE wired devices to provide gigabit connections, such as PCs, printers, and IPTV.

Dedicated 24 PoE+ Ports (250 W Budget) for Numerous Applications
– Compliance with the 802.3af/at PoE+ standard supports up to 30 W on each PoE port. The total 250 W PoE power budget* for the 24× gigabit PoE+ ports makes it has a wide range of applications, such as surveillance, offices, dormitories, and small businesses. It is fully compatible with IP cameras, access points, IP phones, computers, printers, etc.

QoS for a Lag-Free Experience
– Ensures smooth traffic for latency-sensitive applications, such as voice and video

IGMP Snooping for Multicast Optimization
– Ensures a better network experience, especially for applications like IPTV, by optimizing multimedia traffic delivery.

VLAN for Security
– Helps to create a network with higher security and better overall performance by dividing the network into smaller groups

Making Management Easy
– TL-SG1428PE offers network monitoring for users to observe traffic behavior. Through its web-based user interface and management utility, the TL-SG1428PE offers a variety of useful features, including network monitoring, traffic prioritization, and enhanced QoS.

System Self-Healing with PoE Auto Recovery
– The switch automatically detects and reboots the PD devices, such as cameras and APs, when they fall offline or go unresponsive, guaranteeing the stable operation of PoE-connected devices, without need for manual monitoring and restart.

Intelligent Power Management to Prevent Power Overload
– Automatically cuts lower priority ports’ power to ensure high-priority ports’ power supply when the total PoE power consumption exceeds 250 W. This protects the device from power overload operation.

Great Compatibility with PD Detection
– Automatically detects the required PoE power for your device and protects your non-PoE equipment from being damaged.

Wide Operating Temperature with Good Heat Dissipation
– Durable metal casing and professional heat dissipation design ensure the wide operating temperature (0–50?) with reliability.
