GL-816GP-2G

What is the working process of a POE switch?

Detection: At the beginning, the poe switch outputs a very small voltage on the port until it detects that the connection of the cable terminal is a power-receiving device that supports the IEEE802.3af standard.
PD device classification: When the PD of the power receiving device is detected, the poe switch may classify the PD device and evaluate the power loss required by the PD device.
Start of power supply: During the startup period of a configurable time (generally less than 15μs), the poe switch starts to supply power to the PD device from a low voltage until it provides a 48V DC power supply.
Power supply: Provide a stable and reliable 48V DC power for PD equipment to meet the power consumption of PD equipment that does not exceed 15.4W.
Power failure: If the PD device is disconnected from the network, the poe switch will quickly (usually within 300-400ms) stop powering the PD device, and repeat the detection process to detect whether the terminal of the cable is connected to the PD device.

Poe Switch, also named as Poe Switch Ethernet, is one of the Switch that have Poe Port that can do Poe Power Supply.

Introduction

To fulfill the demand of High Power PoE for network applications with Gigabit transmission, GL-COM GL-816GP-2G PoE Gigabit Ethernet Switch is an ideal solution. Each 10/100/1000Mbps port of the it features IEEE 802.3af and IEEE 802.3at Power over Ethernet (PoE) that combine up to 260-watt PoE budget on the whole system. All RJ45 copper interfaces of it support 10/100/1000Mbps auto-negotiation for optimal speed detection through RJ45 Category 6, 5 or 5e cables. It also supports standard auto-MDI/MDI-X that can detect the type of connection to any Ethernet device without requiring special straight or crossover cables. 2 extra gigabit RJ45 for uplink.
