JetNet 5628G is an IEC61850-3 substation-rated Modular Managed Ethernet Switch, equipped with 4 on-board Gigabit RJ45 / MINI GBIC combo ports plus 3 modular slots, for allowing adding up to 24 copper and 18 fiber ports. As a result, it delivers maximum flexibility and simple interface exchangeability for various network connection needs whil reducing the device units and costs.
With the gigabit combo ports users can trunk up to 8G uplink bandwidth and/or form two independent gigabit rings. These dual gigabit rings allow JetNet 5628G to perform as an access-level switch in the power substations ensuring the high bandwidth data transmission.
JetNet 5628G, a special design for substation automation and industrial control room, is verified to conform with the IEC61850-3, IEEE1613 high level environmental certifications. The JetNet 5628G has also passed all the test requirements of NEMA-TS2 certification for traffic control systems and EN 50121-4 EMC certification for Railway installation. JetNet 5628G has the capability of forwarding Data, GOOSE, SCADA message without any loss or collision. With the exclusive MultiRing technology, users can aggregate up to 12 fast Ethernet and 2 gigabit rings into a single switch and ensure network reliability in applications with increased bandwidth and expanded system.
The switch supports up to 9.2Kbytes Jumbo Frame forwarding for efficienlt transmitting large files in industrial environments. JetNet 5628G incorporates LLDP function and perfectly works with the Korenix patented JetView Pro i2NMS for allowing administrators to automatically discover device and efficiently manage the industrial network performance in power substations. Furthermore, the transmission of large files in industrial environments becomes more
efficient and solid.
To fit fulfills and even exceeds the high-end management requirements of IEC61850 substation standards by providing doubled performance and efficient traffic transmission through superb management features, including 8 QoS Priority, 256 Tag VLAN groups, 16K MAC, IGMP Snooping, DHCP Server/Option 82, LACP, SNMPv3...etc.
IEC61850-3 / IEEE 1613 Compatibility
In substation environments, there are many EMI & Environmental Phenomena, such as the electric, magnetic interference, high energy power surge, uncontrolled temperature & humidity...etc. When it comes to the Ethernet for substation automation, the utility companies generally advice integrating networking solutions compliant with the IEC61850-3 and IEEE 1613 standards.
IEC61850-3 defines the standard for the "Communication Networks and Systems in Substations", including "General Requirements" for relevant equipments. The IEEE 1613 defines the “Standard Environmental and Testing Requirements for Communications Networking Devices in Electric Power Substations”.
High Bandwidth and Performance
JetNet 5628G series support 24 fast Ethernet ports plus 4 gigabit combo ports as well as wire speed forwarding and up to 9,216 bytes jumbo frame. The 24+4G combo port design provides benefits and advantages when planning your industrial network architecture.
- Acting as the access switch, 100M speed is still the major and popular in industrial environment.
- Acting as the distribution switch, 4 Gigabit Combo ports are designed for network redundancy, connecting public server or uplink path....
- 2 Gigabit ports are for forming independent ring, or connecting multiple switches with RSTP protection.
- 2 ports for ring and the others for connecting to public servers with higher bandwidth.
- The upper connection can be aggregated with up to 8G bandwidth in full duplex mode by LACP.
- 4 Combo Ports Design to save stock of storing different kinds of transceivers.
Multiple Super Ring (MSRTM) Technology
The JetNet 5628G supports new generation ring technology – MSRTM which includes various new technologies for redundancy applications and structures of different networks.
Maximum 12+2G Rings Aggregation Capability
Korenix JetNet 5628G supports MultiRing which allows aggregating multiple Rapid Super Rings. With the MultiRing technology all the Fast Ethernet and Gigabit Ethernet ports can be part of the ring ports.
Besides, up to 12 100M Rings can be formed and 2 Gigabit Rings can be aggregated to single access switch.
Traditional ring switches, which only allow one ring setting or one ring traffic passthrough, need additional links or settings to connect multiple rings. When there are several ring requests in your network, the setting and environment becomes complex. Unlike these traditional ring switches, with MultiRing feature the lower rings can connect to the JetNet 5628G directly.
Advanced Security by Layer 2/4 Access Control List
In substation automation or industrial control room installation, multiple types of advanced security features are required and must be implemented. The secured Access Control List (ACL) makes it easy to limit certain devices communicating with the other addressed devices and by the specific protocol. Example rules include:
(1) administrator to multiple stations,
(2) stations to stations
(3) stations to public servers…etc.
The ACLs provide “Permit” and “Deny” rules for any or the specific host. The IP address, MAC address and port ID are the destinations allowed to be applied the rules. The protocol ID, QoS tag, TCP flag… are the operations which users prefer to control. The JetNet 5628G is equipped with one layer 2+ switch fabric which provides flexible ACLs for the specified subjects and operations within the same LAN.
Modbus TCP/IP for Factory Automation Network Enhancement
JetNet 5628G supports Modbus TCP/IP protocol for providing enhanced monitoring and maintenance in factory automation applications. It enables users to read the information from the connected advanced Ethernet based devices, such as SCADA systems through their own Modbus/TCP based progress/display/monitor applications, and also monitor the status of the switches easily.
Link Layer Discover Protocol
The Link Layer Discover Protocol (LLDP) was formally ratified as IEEE 802.1AB-2005. LLDP is the Layer 2 protocol that allows the network device/station to advertise connectivity & management information, the identity & major capabilities. It 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 of the stations.
Supporting SNMP, LLDP and JetView protocol, the JetNet 5628G series can be easily discovered, port and ring status can be displayed by JetView Pro, Korenix designed Network Management System or other NMS which support SNMP and LLDP. The software can help administrators efficiently and effectively manage the surveillance network.

Flexible Module Design
The JetNet 5628G provides several types of Fast Ethernet modules. There are 8 10/100Base-TX ports, 4 10/100Base-TX plus 4 100Base-FX and 4 100Base-FX/SC ports plus 2 100Base-FX SFP modules. By turning off the power at the front on the switch it's becoming possible to insert the modules or exchange the module types. The modular design is more flexible for purchasing, provides less storage of stock and field installations. Once the distance is over 100 meters, users can exchange modules without replacing device. When purchasing the JetNet 5628G, please confirm the media type and the port volume.
