ITS (Intelligent Transmit System)

Overview

Tunnel is an isolated drive way with limited space; in the events of accident, the ambulance and sheriff often find it very difficult to locate and get to the incident site. Therefore, a well-organized surveillance system with accurate pinpoint is crucial. JetNet 4508f-m is a web-managed switch and provides dual homing protocol redundancy, highly compatible with other vendors' equipments. The picture on the left is taken from an actual tunnel which implemented 240 pieces of Korenix JetNet 4508f-m in the tunnel supervisory control room, connected to Cisco core switches. The network architecture is demonstrated below. The network consists of two parts---upper network supports the control room in distant location and lower network supports two tunnels, of which, lower network has implemented the JetNet 4508f-m.

Key Product

JetNet 4508f is an 6 port 10/100TX plus 2 port 100Base-FX fiber Industrial Managed Fast Ethernet Switch with SNMP, Web management interface and superb software features for various networking applications. Especially the SNMP can be compatible with OPC server (Kepware) and provides most popular management function in automation; it has remote management ability through standard SNMP tools.
One of the main topics for industrial automation application is to ensure the system running with nonstop transmission. For this requirement, JetNet 4508f provides Super Ring mechanism which is within 20ms recovery time and faster than RSTP.
Besides, JetNet 4508f can merge RSTP and Super Ring function with core switch by Dual Homing function to deliver more reliable networking architecture for the system redundancy.

JetNet 4508f has built in relay output for port and power event. The relay output function will form a short circuit to trigger external one to inform your I.T. engineer when power or port link down event occurred. The port link down alarm is enabled by DIP-switch.
To survive in a harsh operating environment, JetNet 4508f equipped dual power input with redundancy and rigid aluminum case with excellent heat radiation for -10~70oC operating temperature.
