High-capacity Unit for Factory and Metropolitan Long-reach Networking PLANET IGS-6325-16T4S is the smallest yet high-capacity, industrial-grade Layer 3 managed switch with high-density hybrid copper and fiber optic interfaces. It features 16 10/100/1000BASE-T RJ45 ports and 4 100/1000/ 2500BASE-X SFP slots in a DIN-rail type rugged case and can operate stably under the temperature range from -40 to 75 degrees C.  It is designed to be installed in any space-limited cabinets as it is small in size. Its connection distance can be flexibly extended via its powerful ports.  Layer 3 Routing Support The IGS-6325-16T4S enables the administrator to conveniently boost network efficiency by configuring Layer 3 IPv4/IPv6 VLAN static routing manually, and the IPv4 OSPFv2 (Open Shortest Path First) settings automatically. The OSPF is an interior dynamic routing protocol for autonomous system based on link state. The protocol creates a database for link state by exchanging link states among Layer 3 switches, and then uses the Shortest Path First algorithm to generate a route table based on that database.   Redundant Ring, Fast Recovery for Critical Network Applications The IGS-6325-16T4S 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. Network with Cybersecurity Helps Minimize Security Risks The IGS-6325-16T4S comes with enhanced cybersecurity to fend off cyberthreats and cyberattacks. It supports SSHv2, TLS v1.2 and SSL protocols to provide strong protection against advanced threats. Served as a key point to transmit data over multiple long distance fiber optical connections to customer’s critical equipment in a business network, the cybersecurity feature of the IGS-6325-16T4S protects the switch management and enhances the security of the mission-critical network without any extra deployment cost and effort.     Modbus TCP Provides Flexible Network Connectivity for Factory Automation With the supported Modbus TCP/IP protocol, the IGS-6325-16T4S can easily integrate with SCADA systems, HMI systems and other data acquisition systems in factory floors. It enables administrators to remotely monitor the industrial Ethernet switch’s operating information, port information, communication status, and DI and DO status, thus easily achieving enhanced monitoring and maintenance of the entire factory.   1588 Time Protocol for Industrial Computing Networks The IGS-6325-16T4S is ideal for telecom and carrier Ethernet applications, supporting MEF service delivery and timing over packet solutions for IEEE 1588 and synchronous Ethernet. Redundant Power to Ensure Continuous Operation The IGS-6325-16T4S possesses dual DC 9~48V and AC 24V power supply utilized as redundant power supply to ensure its continuous operation. Its redundant power system is specifically designed to handle the demands of high-tech facilities requiring the highest power integrity.    SMTP/SNMP Trap Event Alert The IGS-6325-16T4S provides event alert function to help to diagnose the abnormal device owing to whether or not there is a break of the network connection, or the rebooting response.   Effective Alarm Alert for Better Protection The IGS-6325-16T4S supports a Fault Alarm feature which can alert the users when there is something wrong with the switches. With this ideal feature, the users would not have to waste time to find where the problem is. It will help to save time and human resource. Digital Input and Digital Output for External Alarm The IGS-6325-16T4S supports Digital Input and Digital Output on its front panel. This external alarm enables users to use Digital Input to detect and log external device status (such as door intrusion detector), and send event alarm to the administrators. The Digital Output could be used to alarm the administrators if the IGS-6325-16T4S port shows link down, link up or power failure. IPv6/IPv4 Dual Stack Supporting both IPv6 and IPv4 protocols, the IGS-6325-16T4S helps data centers, campuses, telecoms, and more to experience 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-6325-16T4S can be programmed for advanced Layer 2 switch management functions such as dynamic port link aggregation, 802.1Q tagged VLAN, Q-in-Q VLAN, private VLAN, Multiple Spanning Tree Protocol (MSTP), Layer 2 to Layer 4 QoS, bandwidth control, IGMP snooping and MLD snooping. Via the aggregation of supporting ports, the IGS-6325-16T4S allows the operation of a high-speed trunk group that comes with multiple ports and supports fail-over as well. Efficient Management For efficient management, the IGS-6325-16T4S is equipped with console, Web and SNMP management interfaces.  With the built-in Web-based management interface, the IGS-6325-16T4S 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.  For standard-based monitor and management software, it offers SNMPv3 connection which encrypts the packet content at each session for secure remote management.   Powerful Network Security The IGS-6325-16T4S offers comprehensive 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 and MAC-based user and device authentication. With the private VLAN function, communication between edge ports can be prevented to ensure user privacy.    Advanced IP Network Protection The IGS-6325-16T4S also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and discard ARP packets with invalid MAC address. The network administrators can now construct highly-secure corporate networks with considerably less time and effort than before.   Excellent Traffic Control The IGS-6325-16T4S is loaded with powerful traffic management and QoS features to enhance connection services by telecoms and ISPs. The QoS features include wire-speed Layer 4 traffic classifiers and bandwidth limit that are particularly useful for multi-tenant units, multi-business units, Telco and network service providers’ applications. It also empowers the industrial environment to take full advantage of the limited network resources and guarantees the best performance in VoIP and video conferencing transmission.   Intelligent SFP Diagnosis Mechanism The IGS-6325-16T4S supports SFP-DDM (digital diagnostic monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP transceivers, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
