The reliability of the data underground has been achieved using the MSR ring redundancy technology of the switches – the JetNet 5210G series with the support of MSR were capable of forming rings together. If any link failed, the network could be recovered instantly, within 5ms, without causing any data loss.
Another important factor for the Coal Mining Company to choose JetNet 5210G for the underground installation, has been its robust design: the switches with Level 3 EMC conformance for heavy industry deployments as well as the EN 50121-4 Railway EMC, IEC 61373 vibration/shock approvals are constructed in rugged IP31 enclosures, and have a wide operating temperature range -40~75°C. This means that they could reliably be used under tough conditions without any instability.
The JetNet 6528Gf series fanless rackmount switches were further used in the control room on the ground to ensure reliable backbone connection with the JetNet 5210G switches for collecting the data from underground area. By using the modular design, users could benefit from various copper or fiber connections and get data from a great number of devices installed in a control room. Using SFP combo ports for 100Mbps fiber connection, they collected all the real-time data to send it to the PC through high-speed gigabit combo ports for analyzing the situation under mines.
Besides, as it supports LLDP and Korenix NMS, users could directly get the topology of the network and monitor the devices, change the IPs etc, the group management etc from the control room. Using Korenix switches the company allowed system integrators to prepare highly reliable data transmission from the underground mine to the control center without any data loss and collision and thus providing safe mine operation.
