Industrial Ethernet Switch – JetNet 5828G

Industrial Ethernet Switch - JetNet 5828G


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.
