Slim Specs Table

Power and Performance for Demanding Networks

This switch delivers robust performance with a 56Gbps switching capacity and 41.7Mpps forwarding rate. The 4.1MB packet buffer ensures smooth data handling even during peak usage. Each PoE+ port provides up to 30W of power, making it ideal for power-hungry devices like PTZ cameras or dual-radio access points. The switch automatically detects and delivers the correct power level to connected devices, protecting non-PoE equipment from damage.

Smart Management for Network Control

The TL-SG1428PE offers comprehensive management through its web-based interface. Network administrators can configure VLANs to segment traffic and enhance security, with support for both port-based and tagged VLANs across 32 virtual networks. Quality of Service (QoS) prioritisation ensures latency-sensitive applications like VoIP and video streaming receive bandwidth priority. The switch also includes IGMP snooping for efficient multicast traffic handling, particularly beneficial for IPTV deployments.

Reliable Operation in Business Environments

Built with durability in mind, this 1U rack-mountable switch features a metal chassis and dual fans for effective heat dissipation. The wide operating temperature range of 0-50°C makes it suitable for various installation environments. Intelligent power management automatically adjusts power allocation when the total PoE consumption approaches the 250W limit, ensuring critical devices maintain power. The PoE auto-recovery feature detects unresponsive powered devices and attempts automatic reboot, reducing downtime for connected cameras and access points.

Flexible Deployment Options

With two SFP slots supporting 1000BASE-X fiber connections, this switch easily integrates into existing fiber infrastructure. The auto-MDI/MDIX feature eliminates crossover cable concerns, while auto-negotiation ensures optimal connection speeds. Jumbo frame support up to 10,000 bytes improves performance for large file transfers and storage area networks. The switch’s 8,000 entry MAC address table provides ample capacity for growing networks.

Frequently Asked Questions

Q: Can this switch power 24 full 30W PoE+ devices simultaneously?

A: No, the total power budget is 250W, so not all ports can deliver maximum power at once.

Q: Does this switch support VLAN tagging?

A: Yes, it supports both port-based and tagged VLAN configurations across 32 VLANs.

Q: Is this switch suitable for outdoor deployment?

A: The operating temperature range is 0-50°C, but it lacks weatherproofing for direct outdoor use.

Q: Can I monitor individual port traffic?

A: Yes, the web interface provides port monitoring and traffic statistics.

Q: Does it include any PoE injectors or splitters?

A: No, it’s a standalone switch – you’ll need separate injectors for non-PoE switches.
