Hospitals consume large amounts of energy because they are open 24 hours a day; thousands of employees, patients, and visitors occupy the buildings daily; and sophisticated heating, ventilation, and air conditioning (HVAC) systems control the temperatures and air flow. In addition, many energy-intensive activities occur in these buildings: laundry, medical and lab equipment use, sterilization, computer and server use, food service, and refrigeration.
Link redundancy is critical and redundant ring technology is chosen for the data network of the power electricity system. However, there was only one managed switch acting as Ring Master (RM) to manage the other unmanaged switches in the redundant ring. The single RM became a critical point. Additionally, an up to 300 second long link failure recovery time and high risk of broadcast storm were other significant concerns. Thus, the customer was seeking for a REAL redundancy networking solution for electricity to ensure the continued supply of power.

Korenix Comprehensive Redundant Solutions
Korenix's industrial Ethernet switch - JetNet 4510 has been chosen as the main network system with MSR™ and is supported among the hospital buildings. Every switch in the ring can be the ring Master (RM). In case of RM failure, any one of the other ring switches can recover the failure, so there is no critical point. In the future, the JetNet 4510 has high potential of up to 10 redundant applications per year with average of 7 managed switches.
The JetNet 4510 supports MSR™ which is the next new generation of RSR (Rapid Super Ring) Ring technology. This new technology is perfect for power supply network redundancy applications and structures. The JetNet 4510 allows aggregating up to 5 Fast Ethernet rings, including 1 Fiber ring for long distance data transmission. With the MSR™ technology, a node can be configured to multiple rings with the failover time as little as 5ms and a ZERO-second restore time. In addition, users can extend the ring topology by adding hundreds of JetNet 4510 units to meet the network needs without compromising the speed of the network.
The MSR™ also facilitates the JetNet 4510 to connect with core management switch via standard Rapid Spanning Tree Protocol or through multiple paths or nodes to increase the reliability by Rapid Dual Homing (RDH™) Technology. By integrating MSR™ and Link Aggregation Control Protocol (LACP), the JetNet 4510 is able to enhance the link availability and increase the link capacity. Two or more Fast Ethernet connectiona are bundled in order to increase the bandwidth and to create resilient and redundant links.
JetNet 4510 Industrial 7+3F Ethernet Switch is chosen, because:
JetNet 4510 Industrial 7+3F Ethernet Switch
• Ring master redundancy, no critical point
• Multiple Super Ring, failover < 5ms, restoration = 0ms
• Monitors live status of the network by modbus tcp
• SFP combo ports available for fiber/copper ring
• Easy integration and startup.
