JetNet 5828G series Overview

JetNet 5828G is part of Korenix IEC 61850-3 substation-rated Modular Managed Ethernet Switch Family designed with complete Layer 3 IP Unicast routing features to provide enhanced group management of large scale networks in power substations environments. The switch is equipped with 4 onboard Gigabit RJ45 / MINI GBIC combo ports plus 3 modular slots for delivering maximum 24 copper or 18 fiber ports for various network connection needs while reducing the device units and costs. With the 4 gigabit combo ports users can trunk up to 8G uplink bandwidth and/or form two independent gigabit rings, as a result allowing JetNet 5828G to perform as an access-level switch in the power substations and ensure the reliable high bandwidth data transmission.

JetNet 5828G, a special design for substation automation and industrial control room, is verified to conform with the IEC 61850-3, IEEE1613 high level environmental certifications. The JetNet 5828G has also passed all the test requirements of NEMA-TS2 certification for traffic control systems and EN50121-4 EMC certification for Railway installation.

By choosing JetNet 5828G rackmount switch, administrators get the advantage of wire-speed switching/routing traffic within or among different subnets, choosing the best route from source IP address to destination IP. The injected layer 2/3 data, GOOSE, SCADA message can be transmitted 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. Furthermore, users can configure multiple IP subnets through a single port or the VLAN interface and route multiple rings with each other.

To automatically discover devices and efficiently manage the industrial network performance in power substations, JetNet 5828G incorporates LLDP function and perfectly works with the Korenix patented JetView Pro i²NMS. Moreover, it fulfills and even exceeds the high-end management requirements of IEC 61850-3/IEEE 1613 substation standards by providing doubled performance and efficient traffic transmission through superb management features, including 8 QoS Priority, 256 Tag VLAN groups, 16K MAC address table, DHCP Option 82, MSTP/RSTP, LACP, ACL, VRRP, Layer 3 IP Routing features... etc.

IEC61850-3 / IEEE1613 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 IEC 61850-3 and IEEE 1613 standards. IEC61850-3 defines the standard for the "Communication Networks and Systems in Substations“, including "General Requirements" for relevant equipments. The IEEE1613 defines the “Standard Environmental and Testing Requirements for Communications Networking Devices in Electric Power Substations".

High Bandwidth and Performance

JetNet 5828G 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. 2 Gigabit ports are for forming independent ring, port trunking (LACP) or connecting multiple switches with RSTP protection. Connect the 2 Gigabit ports with ring redundancy and the other 2 gigabit ports to public servers with gigabit bandwidth. All the front interfaces can communicate with each other with wire-speed Layer 2 and Layer 3 switching performance. Acting as the distribution switch, all interfaces have their own forwarding domain, design for network redundancy or routings interfaces. Each F.E., Gigabit ports or VLAN groups can work as the Layer 3 IP interfaces. The interfaces are the default gateway of the client workstations. All the IP subnets attached to the JetNet 5828G can route with wire-speed performance.

Multiple Super Ring (MSR^TM) Technology
The JetNet 5828G supports new generation ring technology – MSR^TM which includes various new
technologies for redundancy applications and structures of different networks.

Maximum 12+2G Rings Aggregation Capability

Routing Protocol
Routing is the process of moving packets through an internetwork, such as the Internet. To Route traffic, a router or layer 3 switch needs to know the destination IP address, sources IP it can learn from, the possible routes, finding the best route, maintaining and verifying routing information. If the next hop address is known or assigned by IT manager or service provider, the static route can direct the correct routing request to the connected interface. If not, the dynamic routing protocol is needed.

The dynamic routing protocol includes unicast routing and multicast routing protocols. The unicast routing protocol includes hop based or distance vector based. RIP is the typical hop based, the less hops path is always the best route. OSPF is the typical distance vector base, the lowest cost is the best route path.

To route multicast services, like the movie, video, industrial automation streams. The multicast routing and related protocols are needed. The MRoute, DVMRP, PIM-DM are supported by JetNet 5828G series.

Advanced Security by Layer 3 Access Control List

After layer 3 interfaces are established, the IP interface or IP subnet can communicate as soon as the IP routing is enabled. To restrict the traffic routing and enhance the security protection, the 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 5828G is equipped with one layer 2+ switch fabric which provides flexible ACLs for the specified subjects and operations within the same LAN.

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 for the stations.

Flexible Module Design
The JetNet 5828G 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 the device. When purchasing the JetNet 5828G, please confirm the media type and the port volume.
