Korenix JetNet 5628G 24+4G-port Modular Rackmount Managed Ethernet Switch, Fanless, 1AC+2DC

JetNet 5628G is an IEC61850-3 Modular Managed Ethernet Switch, equipped with 4 on-board Gigabit RJ45 / MINI GBIC combo ports plus 3 modular slots for maximum 24 10/100 Base-TX Ports or 18 100Base-FX Fiber interfaces ports. The JNM5 series modules are flexible for different port volume, media types and application needs.

JetNet 5628G, a special design for substation automation and industrial control room, is compliant
with the IEC61850-3, IEEE1613 high level environmental certifications. JetNet 5628G has the
capability of forwarding Data, GOOSE, SCADA message without any loss or collision. Different power input types and connectors, including 85-264VAC, 88-370VHDC and 18-48VLDC power inputs, are flexible for field power constructions.

The advantage of choosing JetNet 5628G is that the switch supports on board 4 gigabit ports which allow users to trunk up to 8G uplink bandwidth or to form 2 independent Gigabit rings. The 24 100M interface allows to form 12 100M rings for a reliable network redundancy. This is the world’s only multiple ring redundancy design.

The switch also supports Jumbo Frame forwarding up to 9.2Kbytes. Furthermore, the transmission of
large files in industrial environments becomes more efficient and solid. To fulfill the advanced management, control and security requirements in power substations and control rooms, JetNet 5628G supports various software features. The VLAN, QoS, IGMP, layer 2/4 Access Control List, 802.1x, SNMP V3, LLDP, etc. complete the demand and greatly satisfy technicians’ requests

IEC61850-3 / IEEE1613 Compatibility 
In the substation environment, there are many EMI & Environmental Phenomena, such as the
electric,magnetic, high energy power surge, uncontrolled temperature & humidity...etc. When it
comes to the Ethernet for substation automation, the utility companies generally advise you to comply to
the IEC61850-3 standard and IEC1613 standard. IEC61850-3 is standardized for the design of substation automation.

It defines the standard for the "Communication Networks and Systems in Substations". IEC61850-3 defines the "General Requirements" for relevant equipments. The IEC1613 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 Technology
The JetNet 5628G supports new generation ring technology – MSR which includes various new
technologies for redundancy applications and structures of different networks.

Maximum12+2G rings aggregation capability

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, 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.

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) the 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.
