Redundant Ring, Fast Recovery for Critical Network Applications The IGS-4215-4P4T 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 industrial PoE+ managed switch for surveillance, wireless and VoIP networks, the IGS-4215-4P4T features special PoE management functions: PD alive check Scheduled power recycling PoE schedule PoE usage monitoring PoE extension   Intelligent Powered Device Alive Check The IGS-4215-4P4T can be configured to monitor connected PD (powered device) status in real time via ping action. Once the PD stops working and responding, the IGS-4215-4P4T 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 the administrator’s management burden. Scheduled Power Recycling The IGS-4215-4P4T allows each of the connected PoE IP cameras or PoE wireless access points to reboot at a specified time each week. Therefore, it will reduce the chance of IP camera or AP crash resulting from buffer overflow. PoE Schedule for Energy Savings Under the global trend of energy saving and contributing to environmental protection, the IGS-4215-4P4T can effectively control the power supply besides its capability of giving high watts power. The “PoE schedule” function helps you to enable or disable PoE power feeding for each PoE port during specified time intervals, which is a powerful function to help SMBs or enterprises save power and budget. It also increases security by powering off PDs that should not be in use during non-business hours. Intelligent LED Indicator for Real-time PoE Usage Monitoring Via the power usage chart in the web management interface, the IGS-4215-4P4T enables the administrator to monitor the status of the power usage of the connected PDs in real time. Thus, it greatly enhances the management efficiency of the facilities. Moreover, the IGS-4215-4P4T helps users to monitor the current status of PoE power usage easily and efficiently via its advanced LED indication. Called “PoE Power Usage”, the front panel of the IGS-4215-4P4T has four amber LEDs indicating four different PoE power usages, namely 30W, 60W, 90W, and 120W. 802.3at PoE+ Power and Ethernet Data Transmission Distance Extension In the “Extend” operation mode, the IGS-4215-4P4T operates on a per-port basis at 10Mbps duplex operation but can support 20-watt PoE power output over a distance of up to 250 meters overcoming the 100m limit on Ethernet UTP cable. With this brand-new feature, the IGS-4215-4P4T provides an additional solution for 802.3at/af PoE distance extension, thus saving the cost of Ethernet cable installation.   Environmentally Hardened Design With the IP30 aluminum industrial case, the IGS-4215-4P4T provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb-side traffic control cabinets without air conditioner. Being able to operate under the temperature range from -40 to 75 degrees C, the IGS-4215-4P4T can be placed in almost any difficult environment.   Robust Protection The IGS-4215-4P4T provides contact discharge of ±6KV DC and air discharge of ±8KV DC for Ethernet ESD protection. It also supports ±4KV surge immunity to improve product stability and protects users’ networks from devastating ESD attacks, making sure the flow of operation does not fluctuate.   IPv6/IPv4 Dual Stack Management Supporting both IPv6 and IPv4 protocols, the IGS-4215-4P4T helps the SMBs to step in the IPv6 era with the lowest investment as its network facilities need not be replaced or overhauled if the IPv6 FTTx edge network is set up.     Robust Layer 2 Features The IGS-4215-4P4T can be programmed for advanced switch management functions such as dynamic port link aggregation, 802.1Q VLAN, Q-in-Q VLAN, Multiple Spanning Tree Protocol (MSTP), loop and BPDU guard, IGMP snooping, and MLD snooping. Via the link aggregation, the IGS-4215-4P4T allows the operation of a high-speed trunk to combine with multiple ports such as an 8Gbps fat pipe, and supports fail-over as well.  Also, the Link Layer Discovery Protocol (LLDP) is the Layer 2 protocol included to help discover basic information about neighboring devices on the local broadcast domain.   Efficient Traffic Control The IGS-4215-4P4T is loaded with robust QoS features and powerful traffic management to enhance services to business-class data, voice, and video solutions. The functionality includes broadcast/multicast/unicast storm control, per port bandwidth control, 802.1p/CoS/IP DSCP QoS priority and remarking. It guarantees the best performance in VoIP and video stream transmission, and empowers the enterprises to take full advantage of the limited network resources.   Powerful Security PLANET IGS-4215-4P4T offers comprehensive IPv4/IPv6 Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network applications. Its protection mechanism also comprises 802.1X port-based user and device authentication, which can be deployed with RADIUS to ensure the port level security and block illegal users. With the protected port function, communication between edge ports can be prevented to guarantee user privacy. Furthermore, Port security function allows to limit the number of network devices on a given port. The network administrators can now construct highly-secure corporate networks with considerably less time and effort than before.   User-friendly and Secure Management  For efficient management, the IGS-4215-4P4T is equipped with Command line, Web and SNMP management interfaces. With the built-in Web-based management interface, the IGS-4215-4P4T offers an easy-to-use, platform-independent management and configuration facility. For text-based management, it can be accessed via Telnet and the console port. By supporting the standard SNMP protocol, the switch can be managed via any SNMP-based management software.   Moreover, the IGS-4215-4P4T offers secure remote management by supporting SSHv2, TLSv1.2 and SNMP v3 connections which encrypt the packet content at each session.
