Easy-to-Configure Network Management Interface
For easy of configuration and monitoring, the JetNet 4508 V2 offers various of management interface , such as SNMP, Web Browser, In-Band Telnet and Out-Band Local serial console with command like interface. The switch status as well as all the networking features can be enabled through these management interfaces. The failure notifications are later sent through e-mail, SNMP trap, Local/Remote system log, Fault event alarm relay.
In addition to all these management interfaces, JetNet 4508 V2 also supports Korenix JetView easy network management utility for achieving cost efficiency in system construction as well as the enhanced JetView Pro i2NMS, which integrates comprehensive network monitoring features for auto topology discovery, device auto discovery, group IP address change and firmware upgrade.

Comprehensive Redundant Solutions – Multiple Super Ring (MSRTM)
The JetNet 4508 V2 supports new generation ring technology - MSRTM (Multiple Super Ring), which includes various new technologies for different network redundancy applications and structures. It allows aggregating up to 4 Fast Ethernet Rings. With the MSRTM technology, a node can be configured to multiple rings with the failover time in as little as 5ms and zero-second of restoration time. In addition, users can extend the ring topology by adding hundreds of JetNet series to meet the large-scale network needs without compromising the network speed.
The MSRTM also allows the JetNet series to easily connect with core management switches via standard Rapid Spanning Tree Protocol or through multiple paths or nodes to increase the reliability by RDHTM (Rapid Dual Homing) technology. By integrating MSRTM and Link Aggregation Control Protocol (LACP) the JetNet series can enhance the link availability and increase the overall link capacity. Two or more Fast Ethernet connections are combined in order to increase the bandwidth and to create a resilient and redundant link.

Rapid Super Ring (RSRTM) Technology

Rapid Super Ring is the 2nd generation of Korenix Ring Redundancy technology. The recovery time is greatly improved from 20ms to few ms for both copper and fiber rings. The Ring master can be auto-selected by RSR engine. The 1st ring port of the R.M. is the primary path while the 2nd ring port of the R.M. is the block path. Once the primary path fails, the 2nd path will be recovered within few ms. Besides; the restoration time is also shortened to zero in the R.M. auto-selection mode.

Seamless Ring Port RestorationTM
Seamless restoration is a new Korenix patented technology which can restore a failed ring without causing any loop problem, topology change and packet loss. With zero second restoration time, this mechanism eliminates any unstable status and guarantees the applications running non-stop.

Rapid Dual Homing (RDHTM) Technology
Rapid Dual Homing is also an important feature of Korenix new generation Ring technology. It supports ring coupling with other vendors devices. Moreover, providing easy configuration and multiple redundancies, the failover time is much faster and the restoration time is zero ms. Uplinks can be auto detected and gathered into groups. In each group uplinks are sorted into primary, secondary and standbys based on their link speed. The uplink with the highest speed is more likely to be active path for data transmission. Link aggregation is also integrated into RDHTM. An uplink connection can be a single link or several links aggregated as a trunk, which provides better redundancy and link capacity.

TrunkRingTM
TrunkRing is a new feature in MSR which merges the two technologies of RSR and link aggregation. It takes advantages of aggregation to enhance the link redundancy, while increasing the link speed. The ring will open only if all the aggregated links are broken. Link aggregation can be achieved by either static trunk or LACP. Not all the link sections in a TrunkRing need to be the same. Ring links can be either symmetric or asymmetric. Some are a single path, and the others are aggregated by links where the number of links in a trunk group can be different. Users can enhance the link redundancy at different locations in accordance to the need. The link with less speed is more likely to be used as the backup path for restoring the network to full play capacity.

MultiRingTM

The MultiRingTM provides easier connectivity between two ring networks. The simplest example is to connect two r ings by a single device. Depending on the number of ports and the speed, the JetNet 4508 V2 can connect as a 100Mbps ring and uplink with JetNet 5010G or higher level Korenix Industrial Switch. As shown in the below figure, MultiRingTM technology simply extends the network topology by linking multiple rings into a line or into multiple directions.

In addition to extensibility, MultiRingTM has great diversity of various ring technologies. When MultiRingTM enabled, JetNet 4508 V2 can connect RSR rings, TrunkRingTM and a Super Ring together and simultaneously provide more Fast Ethernet Ring connectivities. This provides extensibility to new technologies while keeping the great backward compatibility.

Link Aggregation Control Protocol

Link Aggregation Control Protocol allows users grouping multiple Ethernet ports in parallel to increase the link bandwidth. The aggregated ports can be viewed as one physical port, so that the bandwidth is higher than just one single Ethernet port. The member ports of the same trunk group can balance the loading and backup with each other. The LACP feature is usually used when higher bandwidth is needed for the backbone network.
This is a cost-effective way for transferring much more data. If the trunk port is also assigned as a ring port, it will become a TrunkRing, which means the bandwidth of ring path has increased with port trunk technology. Now, there is no recovery time when failure occurred. The JetNet 4508 V2 provides a simple and easy way to aggregate port bandwidth into Rapid Super Ring.

IEEE 1588 Precision Time Protocol (PTP)
The Precision Time Protocol is designed to synchronize t ime across Ethernet networks. I t allows synchronization of distributed clocks to submicrosecond accuracy for devices that may have differing precision, resolution and stability. JetNet 4508 V2 supports Auto (or bindery clock), Master and Slave modes for time synchronization to achieve a high level of synchronization within an industrial motion-control environment with a minimum use of network and computing resources. The protocol helps for sequencing event measurements, scheduling outputs, synchronizing actuation, time-stamping, coordinating event records, etc.

Auto Topology Discovery & Efficient Management through LLDP and JetView Pro i2NMS

JetNet 4508 V2 supports topology discovery or LLDP (IEEE 802.1AB Link Layer Discovery Protocol) function that can help users to discover multi-vendor’s network devices on the same segment by an NMS system, which support LLDP function. With LLDP function, NMS can easily maintain the topology map, display port ID, port description, system description, VLAN ID, etc. Once a link failure happens, the topology changed events are updated to the NMS to help users easily maintain the network system.

Besides the SNMP and LLDP protocols, JetNet 4508 V2 series efficiently works with the Korenix patented JetView Pro i2NMS, which in addition to the auto-topology discovery, also delivers MSRTM group management, group IP assignment, firmware upgrade, configuration file backup/ restore ,SNMP MIB Browser /compile, etc. Furthermore, users can export the topology map to diverse formats, such as JPG, BMP, PNG and PDF, for easily managing and trouble-shooting the network. The user-friendly software allows administrators to discover devices automatically and efficiently manage the performance of the industrial network.

Rugged Design for Harsh Environments
The JetNet 4508 V2, compliant with the electromagnetic conformance requirements of Maritime industry, provides a high level of electromagnetic susceptibility exceeding the Railway, Traffic control and Heavy-industrial standards' requirements with distinguished surge protection. Equipped with a rugged aluminum case with high thermal-conductivity design, it is capable of resisting -25~70oC (JetNet 4508 V2) and -40~75oC (JetNet 4508-w V2) wide temperature ranges while providing reliable connectivity under harsh industrial environments.
