PLANET IGS-5225-4P2S L2+ Industrial Managed PoE+ Switch, featuring 4 10/100/1000BASE-T 802.3at PoE+ ports with each port powering up to 36 watts, and 2 x 100/1000X fiber ports in an IP40 rugged but compact-sized case, can be installed in any difficult environment without space limitation. It provides user-friendly yet advanced IPv6/IPv4 management interfaces, abundant L2/L4 switching functions, Layer 3 static routing capability, and advanced ITU-G.8032 ERPS Ring technology to improve the rapid self-recovery capability and PLANET intelligent PoE functions for controlling the PoE outdoor IP surveillance and wireless network applications. It is able to operate reliably, stably and quietly in the temperature range from -40 to 75 degrees C. The IGS-5225-4P2S 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), and redundant power input system into customer's industrial automation network to enhance system reliability and uptime in harsh factory environments. In a simple Ring network, the recovery time of data link can be as fast as 10ms. The cybersecurity feature that virtually needs no effort and cost to have includes the protection of the switch management and the enhanced security of the mission-critical network. Both SSH and SSL protocols are utilized to provide strong protection against advanced threats. The network administrator can now construct highly-secure corporate networks with considerably less time and effort than before.
