CIS-500 series are a cost-effective 6-port redundant ring switches which adopt the newest structure to support ultra fast redundant ring function within 10ms (in 250 units). Its excellent performance protects your mission-critical applications from any network interruptions or temporary malfunctions. Additionally, it can automatically switch to other ports in 10ms when the master link fails. Therefore, CIS-500 series are the best cost-effective option for redundant Ethernet network.

World’s fastest redundant recovery time < 10 ms (S-Ring)
CIS-500 series support the fastest 10ms redundant recovery time which makes Ethernet connection non-stop. If your primary communication path is disconnected, the Redundant Ring Technology would provide a redundant path to recover this fault.
CIS-500 series provide you with a solid foundation of highly faulttolerant network and easily-managed network.

Event notification through e-mail & system log
The switch provides event notification through email.  In addition, it can be configured remotely by Web and windows utility (Cayee-VIEW). 

6 redundant LAN ports: device communication redundant mode
After selecting the redundant mode and connecting other LAN ports to different switches or  the same switch with different ports, CIS-506 can automatically switch to other LAN ports within 10mS, and still guarantee a non-stop connection while the connection of master link fails.  Such a design can avoid any malfunctions and breakdown of data transmission.
