Managed Industrial Switch, L2+, 16 x 10/100/1000T RJ-45, 4 x 100/1000X SFP
PLANET IGS-20040MT is an Industrial 20-port Full Gigabit Managed Ethernet Switch specially designed to build a full Gigabit backbone to transmit reliable and high speed data in heavy industrial demanding environments and forward data to remote network through fiber optic. It provides 16-port 10/100/1000Base-T copper and 4 extra 100/1000Base-X SFP fiber optic interfaces delivered in an IP30 rugged strong case with redundant power system. Besides support for 40Gbps switch fabric to handle extremely large amounts of video, voice and important data in a secure topology, the IGS-20040MT provides user-friendly but advanced IPv6 / IPv4 management interfaces and abundant L2 / L4 switching functions. It is the best investment for industrial business expanding or upgrading its network infrastructure.
Environmentally Hardened Design
With IP30 aluminum industrial case protection, the IGS-20040MT 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. It also possesses an integrated power supply source with wide range of voltages (12 to 48V DC or 24V AC) for worldwide high availability applications requiring dual or backup power inputs. Being able to operate under the temperature range from -40 to 75 degrees C, the IGS-20040MT can be placed in almost any difficult environment.
Redundant Ring, Fast Recovery for Critical Network Applications
The IGS-20040MT 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 certain simple Ring network, the recovery time of data link can be as fast as 20ms.
Digital Input and Digital Output for External Alarm
The IGS-20040MT supports Digital Input and Digital Output on its upper panel. The external alarm enables users to use Digital Input to detect external device’s 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-20040MT port is link-down, link-up or power-dead.
Robust Layer2 Features
The IGS-20040MT can be programmed for advanced switch management function, such as dynamic port link aggregation, Q-in-Q VLAN, Multiple Spanning Tree Protocol(MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD snooping. The IGS-20040MT allows the operation of a high-speed trunk combining multiple ports. It enables a maximum of up to 10 groups of 8 ports for trunking and supports connection fail-over as well.
IPv6 / IPv4 Full-functioned Secure Switch for Building Automation Networking
The IGS-20040MT is the ideal solution to fulfilling the demand of IPv6 management Gigabit Ethernet Switch, especially in the Industrial hardened environment. It supports both IPv4 and IPv6 protocols, advanced Layer 2 to Layer 4 data switching and redundancy, QoS traffic control, network access control and authentication, and Secure Management features to protect customer’s industrial and building automation network connectivity with reliable switching recovery capability that is suitable for implementing fault tolerant and mesh network architectures.
IPv4 and IPv6 VLAN Routing for Secure and Flexible Management
The IGS-20040MT offers IPv4/IPv6 VLAN routing feature which allows to cross over different VLANs and different IP addresses for the purpose of having a highly-secured, flexible management and simpler networking application.
User-friendly Secure Management
For efficient management, the IGS-20040MT is equipped with console, Web and SNMP management interfaces. With the built-in web-based management interface, the IGS-20040MT offers an easy-to-use, platform independent management and configuration facility. The IGS-20040MT supports SNMP and it can be managed via any management software based on standard of SNMP v1 and v2 protocol. For reducing product learning time, the IGS-20040MT offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command from these switches. Moreover, the IGS-20040MT offers remote secure management by supporting SSH, SSL and SNMPv3 connection which can encrypt the packet content at each session.
Flexible and Extendable Solution
The 4 mini-GBIC slots built in the IGS-20040MT support dual-speed as it features 100Base-FX and 1000Base-SX/LX SFP (Small Form-factor Pluggable) fiber-optic modules, meaning the administrator now can flexibly choose the suitable SFP transceiver according to the transmission distance or the transmission speed required to extend the network efficiently.
Intelligent SFP Diagnosis Mechanism
The IGS-20040MT supports SFP-DDM (Digital Diagnostic Monitor) function that can easily monitor real-time parameters of the SFP for network administrator, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
