Date:2014-06-08 Layer 3 Industrial Ethernet Switches offer high port density.
Taipei, Taiwan — The scale of networks in industrial environments have constantly grown, spurring the need for inter-device communications between different network segments. More efficient and secure management of the devices has thus become a necessity. This is where Layer 3 comes into play. Network equipment with Layer 3 functions not only enables cross-network data transmission, but also separates networks into several segments to achieve a higher level of security. As a result, Layer 3 has been increasingly adopted in industrial applications. With growing importance of Layer 3, ORing has launched three Layer-3 Gigabit industrial Ethernet switches featuring a high port density.

The newly launched Layer 3 switches consist of the IGPS-R9084GP, IGS-R9812GP, and the DGS-R9812GP_AIO_S. With the provision of a total of 12 to 20 Gigabit ports, these models are equipped with 100/1000Base-X SFP modules to offer more versatile and longer-distance connection options. The Ethernet ports of the IGPS-R9084GP are compatible with the IEEE802.3af / IEEE 802.3at PoE standards, allowing each port to provide up to 30Watt power to a PD device.

Apart from static routing, these models will automatically forward packets to the destination device even if it is not on the same network and then update their MAC tables through the learning ability. Since the Layer 3 function can communicate with different network segments, each LAN will remain separated when no cross-network transmission is required, hence higher security and bandwidth usage efficiency. With the ability to connect different LANs together when necessary, the devices can provide excellent network scalability.

The Layer 3 switches also support RIP (Routing Information Protocol) and VRRP (Virtual Router Redundancy Protocol), the former can locate the shortest transmission route for packets and the latter can provide routing redundancy. When the primary Layer 3 switch fails, the connection will automatically switch to a back-up L3 switch to ensure uninterrupted transmission. The characteristic of high availability makes the IGPS-R9084GP, IGS-R9812GP, and the DGS-R9812GP_AIO_S especially ideal for industrial applications such as IP surveillance, factory automation, and rolling stock where continued connectivity is a must. With ORingfs central management system, customers will be able to manage all devices on one single platform.
