Redundant Ring, Fast Recovery for Critical Network Applications
The GS-4210-24P2S supports redundant ring technology and features strong,
rapid self-recovery capability to prevent interruptions and external intrusions.
It incorporates advanced ITU-T G.8032 ERPS (Ethernet Ring Protection
Switching) technology, Spanning Tree Protocol (802.1s MSTP) into customer’s
network to enhance system reliability and uptime in various environments.

Built-in Unique PoE Functions for Powered Devices Management
As the PoE managed switch for surveillance, wireless and VoIP networks, the GS-
4210-24P2S features special PoE management functions:
■ PD alive check
■ Scheduled power recycling
■ PoE schedule
■ PoE usage monitoring
■ PoE Extension
Intelligent Powered Device Alive Check
The GS-4210-24P2S can be congured to monitor connected PD (powered device)
status in real time via ping action. Once the PD stops working and responding, the
GS-4210-24P2S will resume the PoE port power and bring the PD back to work. It
will greatly enhance the network reliability through the PoE port resetting the PD’s
power source and reducing administrator management burden.
