Korenix JetNet 4006 series is an Industrial Managed Fast Ethernet Ring switch equipped with 4 10/100 Mbps ports plus 2 10/100 Mbps uplink ports for forming redundant connection in industrial Ethernet applications. The LLDP design allows the switches to be managed and configured easily by a single administrator console, where the topology can be automatically drawn in just seconds. The JetNet 4006 series combines more advanced Layer2 management protocols, such as the DHCP option 82, VLAN, IGMP snooping or SNMPv3 for efficiently controlling and managing the network performance in industrial environments.

To provide network redundancy with guaranteed secure and reliable data transmission, JetNet 4006 series supports Korenix patented fast network ring recovery technology - the Multiple Super Ring (R.S.R.) which can recover network failures in just 5 milliseconds. The RSR co-exists with the IEEE 802.1d RSTP:2004 standard to deliver non-stop transmission by Rapid Dual Homing (R.D.H.) technology.

JetNet 4006 is designed with a slim IP31 rugged aluminum alloy injection case with great heat radiation ability to work reliably under high temperature environment. To provide more reliability for industrial applications, it supports wide range power input DC 12~48V with auto polarity reverse function.

Auto Network Device & Topology Discovery With the increasing popularity of internet applications, network traffic becomes heavier and hard to monitor and diagnose. To solve these issues, IEEE organization announced a new standard, the IEEE 802.1AB Link Layer Discovery Protocol for device auto discovery as well as for building infrastructure map by NMS. JetNet 4006 incorporates the LLDP function and efficiently works with the Korenix patented JetView Pro i2-NMS, to easily discover devices and automatically draw out network topology with the link interface number of each device. This feature allows system administrators efficiently maintain the network system.

Comprehensive Redundant Solutions- Multiple Super Ring (MSR)

The JetNet 4006 supports new generation ring technology - MSR (Multiple Super Ring), which includes RSR and Rapid Dual Homing for different network redundancy applications and structures. The two 10/100TX Ethernet ports of JetNet 4006 provide high speed uplink to connect with higher level backbone switches with Korenix MSR network redundancy technology.	To ensure continuous transmission, the RSR topology allows linking up the backup path in 5ms when main path disconnection occurs. Furthermore, to integrate with other core Switches JetNet 4006 provides Rapid Dual Homing function which merges R.S.R. and RSTP protocols in one redundant port.

Full Layer2 Network Management Interface
JetNet 4006 supports versatile management interfaces including secure Web browsing-HTTPS, secure remote Telnet management- S.S.H., SNMP v1/v2c/v3, RS-232 local console and JetView Pro for fast and easy installation. All the real-time system status can be simply monitored and configured through these management interfaces.

Auto Device IP Obtain, Assign & Relay by DHCP Option 82
In large network systems, system IP address is difficult to maintain and efficiently assign to each device. Usually, it is listed in a table and it takes long time for IT engineers to configure those deivces one by one unless using the DHCP technology. JetNet 4006 supports various DHCP functions, including DHCP Client, Server and Relay (option 82). Using these features, it can obtain system IP address from DHCP Server, assign IP address to another link partner with IP& MAC address binding or exclude specified IP address, re-routing DHCP request to other network subnets. Therefore, system adaministrators can easily and efficiently manage the IP address without on-site configuration.

Quality of Service & Port-Based VLAN
To improve transmission performance, JetNet 4006 adopts QoS function with 8:4:2:1 WRR forwarding scheme and port-based VLAN with Tag ID modification function. These features ensure that the real-time service will be processed in low forwarding latency, like chatting via network, real-time security through video, etc.
