TP-Link 28-Port PoE+ Smart Switch

TP-Link TL-SG1428PE | 28-Port Managed PoE+ Gigabit Switch

The TP-Link TL-SG1428PE is a professional 28-port managed PoE+ Gigabit switch designed for businesses needing reliable power and data delivery to multiple devices. With 24 PoE+ ports delivering up to 30W each and a total 250W budget, this switch handles IP cameras, access points, IP phones, and other powered devices alongside standard gigabit connections for computers and printers.

Key Specifications

24 PoE+ Ports Power Multiple Devices Simultaneously

The TL-SG1428PE’s 24 dedicated PoE+ ports eliminate the need for separate power injectors or adapters. Each port delivers up to 30W, supporting everything from high-power IP cameras to Wi-Fi 6 access points. The total 250W budget ensures reliable operation across all connected devices, making it ideal for surveillance systems, office networks, or small business deployments where multiple powered devices need centralized management.

Intelligent Power Management Prevents Overload

When total PoE consumption exceeds 250W, the switch automatically prioritizes critical ports and cuts power to lower-priority connections. This intelligent power allocation protects the device from overload while maintaining essential services. The system also includes PD detection that prevents damage to non-PoE equipment by automatically identifying power requirements before delivering any voltage.

Advanced Network Management for Optimal Performance

Beyond basic switching, this managed device offers comprehensive control through its web interface. Quality of Service (QoS) prioritizes latency-sensitive traffic like VoIP and video streaming, while IGMP snooping optimizes multicast delivery for IPTV and similar applications. With 32 VLANs, port-based and tagged VLAN support, and link aggregation, you can segment networks for security and improved performance across different user groups or device types.

Robust Build Quality for Continuous Operation

The metal chassis and dual-fan design ensure reliable operation in temperatures from 0-50°C, making it suitable for network closets and equipment racks. With 8000 MAC address entries, 10000-byte jumbo frames, and a 56Gbps switching capacity, the TL-SG1428PE handles demanding network environments without bottlenecks. The store-and-forward architecture with 4.1MB packet buffer memory maintains data integrity even under heavy load.

Frequently Asked Questions

Q: Can this switch power 24 devices simultaneously at full 30W each?

A: No, the total 250W budget means not all ports can deliver 30W simultaneously. Power is allocated based on device needs and priority settings.

Q: Does this switch support VLAN configuration?

A: Yes, it supports 32 VLANs with both port-based and tagged VLAN features for network segmentation.

Q: Is this switch suitable for outdoor use?

A: No, it’s designed for indoor rack mounting with an operating temperature range of 0-50°C.

Q: What management options are available?

A: The switch offers web-based management, SNMP v1/v2c/v3, and a management utility for configuration and monitoring.

Q: Does it support link aggregation?

A: Yes, link aggregation is supported for combining multiple ports to increase bandwidth or provide redundancy.
