With fewer unit installation capability, the access ports share wider on-chip backplane, faster local transmission latency, efficient upstream transmission. Besides all the ports can be managed through a single management agent. The JetNet 5018G is equipped with 16 10/100TX Fast Ethernet ports and Base-T/Gigabit SFP combo ports. The SFP ports accept all types of Gigabit SFP transceivers, including Gigabit SX, LX, LHX, ZX and XD for several connections and distances. The 16+2G design allows aggregating up to 8 100M rings plus 1 Gigabit ring. This is a unique and patented protected ring technology. The JetNet 5018G is designed as rugged surface in aluminum material, with efficient heat dispersion and wide operating temperature. JetNet 5018G supports Jumbo frame, featuring up to 9,216 bytes packet size for large size file transmission, which is the trend for future industrial application requests. The embedded software supports 802.1s MSTP, RSTP and Multiple Super Ring technology for ring redundancy protection. Besides, JetNet 5018G support full layer 2 management features, such as the VLAN, IGMP Snooping, LACP for network control, SNMP, LLDP for network management. The secured access is protected by Port Security, 802.1x and flexible Layer 2/4 Access Control List. With JetNet 5018G, you can fulfill the technicians needs of having the best solution for the industrial Ethernet infrastructure.

2 High Bandwidth and Performance The JetNet 5018G equipped with M Fast Ethernet plus 2 Gigabit Ethernet ports, totally requests at least 7.2G backplane for wire-speed and bi-directional transmission. To meet the requests, there are 2 types of system architecture - non-blocking and blocking. In non-blocking architecture, the switch fabric should provide higher backplane than are the front ports requests. No matter it s a one to one or fully mesh network, the throughput is always 100% without any loss. The blocking architecture is usually implemented in non-single chipset solution. Limited backplane may cause traffic jam when there is a heavy loading transmission among the ports. The JetNet 5018G embedded 12.8G backplane is much higher than the system requires. All the traffic can be switching without blocking and loss. Up to 9K Jumbo frame allows transmitting larger files with less segments. The high bandwidth and performance solution guarantees the high capabilities of the product.

The typical Ethernet frame ranges from 64 to 1518 bytes. This is sufficient for general usage. However, when users want to transmit large files, the files may be divided into many small size packets. While the transmitting speed becomes slow, 9KBytes Jumbo frame can solve the issue. Jumbo Frame examples: Transmitting large files, like the size of the LCD s bitmap type circuit may reach up to 800MB. Network servers usually progress backups for lots of large files. The Large File is divided into many small packets Before transferring Type 1: Typical Ethernet Packet, maximum size is 1518 bytes 1518 bytes 1518 bytes 1518 bytes 1518 bytes 1518 bytes 1518 bytes Type 2: Jumbo Frame Packet, maximum size is 9216 bytes 9216 bytes

3 Jumbo Frame Ring When running Jumbo Frame within the industrial ring environment, all the switches within the ring must support Jumbo Frame. Once there is any Jumbo Frame unaware switch within the ring, the Jumbo Frame would be dropped. Beijer Electronics provides complete Jumbo Frame supported switches, the switches help to form the Jumbo Frame ring easier. you can choose and install JetNet rackmount switch in control room, and JetNet Din Rail switch as the entry level Jumbo frame switch for formnig a jumbo frame ring MTU=1,518 MTU=9,216 JetNet 5628G Gigabit Jumbo Frame Ring JetNet 5018G Not Supported Jumbo Frame Gigabit SFP Port The JetNet 5018G is equipped with 2 Gigabit RJ-45/SFP Combo Ports. The uplink ports bandwidth is often the bottleneck, when a high port density switch connects to many ports.

Gigabit Rapid Super Ring 3rd gigabit uplink to other network 3rd gigabit to the public server 100 / 1000Mbps DDM Transceiver for High Quality Monitoring The JetNet 5010G SFP socket supports 100Base- FX Single/Multi-Mode and 1000Base-SX/LX/LHX/XD Multi/ Single-Mode transceiver. 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. Comprehensive Redundant Solutions Multiple Super Ring (MSR TM ) The JetNet 5010G supports MSR TM (Multiple Super Ring); the new generation of RSR (Rapid Super Ring) technology. This new technology includes various new features for different network redundancy applications and structures. The JetNet 5010G allous aggregating up to 5 rings, including 4 Fast Ethernet and 1 Gigabit ring. With the MSR TM technology, a node can be configured to multiple rings with the failover time in as little as 5ms and ZERO-second of restore time. In addition, users can extend the ring topology by adding hundreds of JetNet 5010G to meet the network needs without compromising the speed of the network. The MSR TM also facilitates the JetNet 5010G to connect with core management switch via standard Rapid Spanning Tree Protocol or through multiple paths or nodes to increase the reliability of the Rapid Dual Homing (RDH TM ) Technology. By integrating MSR TM and Link Aggregation Control Protocol (LACP), the JetNet 5010G can enhance the link availability and increase the link capacity. Two or more Fast Ethernet connection are bundled in order to increase the bandwidth and to create resilient and redundant links.

15 TrunkRing TM Symmetric TrunkRing TM Asymmetric TrunkRing TM TrunkRing TM is a new feature in MSR TM which merges the two technologies of RSR and link aggregation. It takes advantage 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 protocol. Not all the link sections in a TrunkRing TM need to be the same. Ring links can be either symmetric or asymmetric. Some are a single link, 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. Asymmetric TrunkRing JetNet 5010G MultiRing TM MultiRing TM provides easier connectivity between two ring networks. The simplest example is to connect two rings by a single device. Depending on the number of ports, a device can even gather multiple rings together. As shown in the figure, MultiRing TM technology simply extends the network topology by linking multiple rings into a line or into multiple directions. In addition to extensibility, MultiRing TM has great diversity of various ring technologies. With MultiRing TM enabled, a device can connect RSR TM rings, TrunkRing TM and a ring of Super Ring together. Which provides extensibility to new technologies while keeping the great backward compatibility. JetNet 5010G RSR RSR TrunkRing JetNet 5010G Simply connect 2 rings by a device JetNet 4508 V2

16 Rapid Dual Homing (RDH TM ) Technology Rapid Dual Homing (RDH TM ) replaces DualHoming II and can be used for ring coupling. While keeping easy configuration and multiple redundancies, the failover time is much faster (less than 50 ms) and the restore time is ZERO (seamless restoration). 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 the active path for data transmission. Link aggregation is also integrated into RDH TM. An uplink can be a link or several links aggregated as a trunk, which provides better redundancy and link capacity. 1-to1 connection n-to1 connection 1-to-n connection n-to-n connection trunk connection Rapid Dual Homing Ethernet Ethernet JetNet 5010G Ring Coupling Ethernet Ethernet JetNet 5010G Various Network Control and Security Features The JetNet 5010G provides various network control and security features. The Network Control feature allows users to optimize their industrial environment. The supported features include VLAN, Private VLAN, QinQ, IGMP Snooping, Quality of Service (QoS), Link Aggregation Control Protocol (LACP), Rate Control. The security also helps users to avoid hackers attack. The features included are, DHCP Server, IP and MAC Binding, 802.1x Access Control, SSH, IP Access Table and Port Security.

17 Port Security Port Security is an enhanced security feature provided by JetNet 5010G. Port Security is also known as, Port and MAC Binding. Users can bind a specific MAC address to a specific port, add the MAC and Port binding entry/entries to the port security table. After enabling this, only the PC with the available MAC address can access the network through the switch. The other PCs can t even pass the traffic through the port. Port 1 Network Port Security Table Port VID Mac Address Port 1 1 MAC B PC A MAC A PC B MAC B PC C MAC C PC D MAC D A Built-in Watchdog Timer With a Built-In Watchdog Timer, the JetNet 5010G performs a warm boot (restarting the switch) automatically when the switch system locks up. It saves the effort of maintenance for keeping network alive if the switch can recover by itself. Robust Mechanical Design Watchdog Timer CPU Failure = 6 sec => Internal Reset 00:00:06 00:00:00 JetNet 5010G's outstanding outlook is rock solid with strong functionality. Using aluminum extrusion case with IP 31 class protection, light weight, rigid shell and excellent thermal conductivity units, it can operate reliably under harsh industrial environments. Link Aggregation Control Protocol Link Aggregation Control Protocol (LACP) allows you to group multiple Ethernet ports in parallel to increase the link bandwidth. The aggregated ports can be considered 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 an inexpensive way for users to transfer much more data. If the trunk port is also assigned as a ring port, it will become as a TrunkRing TM, which means, that the bandwidth of ring path has increased with port trunk LACP technology. Now, there is no recovery time when failures occur. The JetNet 5010G provides a simple and easy way to aggregate port bandwidth into Rapid Super Ring.

18 LLDP and JetView Pro i 2 NMS for Auto Topology Visualization The Link Layer Discovery Protocol (LLDP) was formally ratified as IEEE 802.1AB LLDP is the Layer 2 protocol that allows the network device/station to advertise connectivity & management information, the identity & major capabilities. If receives and establishes network management information on the local same network. In industrial environments, most vendors provide their own discovering protocols, window utility or other tools to manage their switches. The LLDP protocol fixes the interoperability among them. With LLDP supported, users can easily browse the network devices and establish the network management information schema about the stations. With SNMP, LLDP and JetView protocols supported, JetNet 5010G series can be easily discovered, their port and ring status can be displayed by JetView Pro, the Network Management System or other NMS, which supports SNMP and LLDP. The software can help administrators efficiently and effectively manage the industrial network. Easy-to-Configure Network Management Features The JetNet 5010G also provides users many advanced management features. It can be configured smartly by JetView, JetView Pro, Web browser, SNMP, Telnet and RS-232 console Command Line Interface (CLI). It provides Failure notification by , SNMP Trap, System Log, Digital Input and Fault Relay. The JetNet 5010G also supports Built-In Watchdog Timer for system recovering when detecting CPU failure. Network RS-232 JetView, Web, SNMP, Telnet Modbus TCP/IP for Factory Automation Network Enhancement The Modbus TCP/IP protocol is supported in JetNet 5010G series for factory automation applications. It enables administrator to connect to data acquisition (SCADA) system and read the switch's operating information using its own Modbus TCP/IP master program for monitoring and maintaining switch s status. With the supported Modbus TCP/IP, the JetNet 5010G series become an element of factory automation such as the Programmable Logic Controller (PLC), Distributed Control System (DCS), and allow users to monitor/ maintain factory equipment on the HMI (Human Machine Interface) system, including production information and communication status. Therefore, user does not need to integrate multiple management platforms to monitor factory equipment: with just a single JetNet 5010G platform users can easily achieve enhanced monitoring and maintenance of the entire factory.

The 3 combo ports offer flexibility for additional fiber connections by plugging different types of 100MM SFP modules, which can support 2KM in Multi-Mode or 120KM in Single-Mode. The combo ports make port combination even easier, such as 8 RJ ports and 2 fiber ports, or 9 RJ ports and 1 fiber port. The standard 10 port Fast Ethernet switch greatly reduces total cost by up to 15% for fiber uplink network. In addition to cost savings, the flexible design of the JetNet 4510 can adapt to the world's fastest Ring Technology. It only takes 5ms to recover from link failure, no matter how many nodes are inside a ring. Moreover the restoration time is zero. The patented Multiple Super Ring provides most flexible ring topologies, such as shared link of multiple rings, or shared unit of multiple rings, making it the best possible. The Multiple Super Ring is highly compatible to Rapid Spanning Tree by the new Dual Homing plus design. JetNet 4510 also enhances security designs, such as SNMP V3, SSH, 802.1X, etc.

23 3 Flexible Fast Ethernet Combo Ports The JetNet 4510 is designed with three combo Fast Ethernet ports. Each combo port combines one Small Form factor Pluggable (SFP) socket for 100Mbps multimode or single mode SFP transceiver, as well as one RJ-45 copper port in 10Mbps full duplex, 100Mbps half /full duplex link mode. The switch will automatically detect the priority of cable connections for each combo port. Users are able to connect two 100Mbps SFP ports of JetNet 4510 as a Fast Ethernet Fiber Redundant Ring topology and the third combo port as a fiber uplink port or an applicable port. 100Mbps DDM SFP transceiver for High Quality Monitoring The JetNet 4510 Series SFP socket supports 100Base-FX single-mode/multi-mode 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.

The aggregated ports can be considered 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 an inexpensive way for users to transfer much more data. If the trunk port is also assigned as a ring port, it will become a TrunkRing TM, which means that the bandwidth of ring path has increased with port trunk LACP technology. Now, there is no recovery time when failures occur. The JetNet 4510 provides a simple and easy way to aggregate port bandwidth into Rapid Super Ring.
