1 Introduction
Welcome to Korenix JetNet 5210G Series Industrial 8-Port + 2Gigabit Copper / SFP Managed
Ethernet Switch User Manual. Following topics are covered in this chapter:
1.1Overview
1.2Major Features
1.3Package Checklist
1.1 Overview
Korenix JetNet 5210G, the revolutionary DIN Rail type industrial Gigabit Managed Switch is designed with
eight 10/100TX and two Gigabit RJ-45 / SFP combo ports.
The two Gigabit Ethernet combo ports provide high speed uplink to connect with higher level backbone
switches with Korenix MSRTM network redundancy technology, while ensuring the reliability of video
transfer through the exclusive 5ms recovery time. By supporting various connection types, including
10/100/1000Mbps RJ-45 copper or 100Mbps, 1000Mbps Fiber, the Gigabit uplink ports further enlarge
the ring infrastructure.
With IEC 61000-6-2 / 61000-6-4 Heavy Industrial EMC certified design, including robust enclosure and -
40~75°C wide operating temperature range, JetNet 5210G ensures high performance of the surveillance
network under vibrating and shock environments in rolling stocks, traffic control systems and other harsh
applications.
100/1000Mbps DDM SFP transceiver for High Quality Monitoring
The SFP sockets of the JetNet 5210G supports 100Mbps and 1000Mbps SFP type fiber transceiver with
speed detection and independent indication. Moreover, it supports DDM (Digital Diagnostic Monitoring)
type SFP transceivers allowing users to diagnose optical cable transmission problem through
maintenance and debugging of the optical signal quality by DDM without the need of an extra optical
cable analyzer, as a result greatly saving time and system costs.
Rapid Super Ring (RSRTM) Technology
The JetNet 5210G supports Rapid Super Ring technology, which is the 2nd generation of Korenix Ring
Redundancy technology. The recovery time is greatly improved from 30ms to few ms for both copper and
fiber ring. 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.
Comprehensive Redundant Solutions – Multiple Super Ring ( MSRTM)
JetNet 5210G also supports advanced Ring technology – M.S.R. (Multiple Super Ring) which includes

JetNet 5210G User Manual
3
various new technologies for different network redundancy applications and structures. The supported
MSR allows JetNet 5210G aggregating up to 5 Rapid Super rings includes 4 Fast Ethernet plus 1 Gigabit
Ethernet rings into one switch. With the MSRTM technology, a node can be configured to multiple rings
with the failover time. In addition, users can extend the ring topology by adding hundreds of JetNet
managed switches to meet the large-scale network needs without compromising the network speed. The
MSRTM also allows JetNet 5210G managed switch to easily connect with core management switches via
standard Rapid Spanning Tree Protocol (RSTP) or through multiple paths or nodes to increase the
reliability by RDHTM (Rapid Dual Homing) technology. By integrating MSRTM and LACP (Link Aggregation
Control Protocol), the JetNet series can enhance the link ability 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.
Seamless Ring Port Restoration TM
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 a 0 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 the important feature of Korenix new generation Ring technology. It supports
ring coupling with other vendors and with 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 by 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 MSRTM which merges the two technologies of RSRTM and link aggregation.
It takes advantages of aggregation to enhance the link redundancy, while increase 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. And the link with less speed is more likely to be used as the backup
path for restoring the network to full play capacity.
Link Aggregation Control Protocol
Link Aggregation Control Protocol allows you grouping multiple Ethernet ports in parallel to increase the

JetNet 5210G User Manual

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 you need higher bandwidth for the
backbone network. This is a cost-effective way for you to transfer much more data.
Auto Topology Discovery & Efficient Management through LLDP and JetView Pro i2NMS
JetNet 5210G 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 supports LLDP function. With LLDP function, NMS can easily maintain the topology map,
display port ID, port description, system description, VLAN ID and so on. Once a link failure happens, the
topology changed events are updated to the NMS to help users easily maintain the network system. Like
as the JetView Pro, not only supports topology discovery, it also delivers group IP assignment, firmware
upgrade, configuration files backup/ restore ,SNMP MIB Browser /compile, MSRTM group management
and also allows user to export topology map to drawing file-JPEG, BMP, PNG or PDF for other
application.
Outstanding Management and Enhanced Security
The JetNet 5210G provides various network control and security features to ensure the reliable and
secure network connection. To optimize industrial network environment the switch supports advanced
network features, such as Tag VLAN, IGMP Snooping, Quality of Service (QoS), Link Aggregation Control
Protocol (LACP), Rate Control, etc. The switch can be smartly configured through JetView, JetView Pro
(Korenix’s advanced management utility), Web Browser, SNMP, Telnet and RS-232 local console with its
command like interface. The failure notifications are sent through e-mail, SNMP trap, Local/Remote
system log, Multiple event alarm relay.
To avoid hacker’s attacks and ensure the secure data transmission, JetNet 5210G series features DHCP
client, DHCP server with IP and MAC binding, 802.1X Access Control, SSH for Telnet security, IP Access
