Industrial managed switches offer high speed
The recovery time of a Gigabit fibre ring or a fast Ethernet copper ring connected in JetNet 5010G can reach to less than 5ms.
Switches and convertors handle strenuous tests
The JetNet 5010G/3010G/4508/2005 and JetCon 1301 provide 1200V AC port to port isolation protection to protect the operator from electrical shock.
The two different types of switches use different network redundant ring topology; commercial switches use standard RSTP protocol, whereas industrial Ethernet switches use proprietary ring protocols such as Korenix Super Ring.
The compatibility will be a critical issue for the whole system's network redundancy.
Korenix JetNet 4500 Dual Homing technology provides a solution for the compatibility issue.
RSTP over Super Ring or Dual Homing is to provide an advanced redundancy network solution by connecting switches running in different redundancy protocols (ie IEEE802.1w Rapid Spanning Tree Protocol and Super Ring) and extend the network redundancy coverage.
Redundancy is achieved by connecting two ports from two separate switches using Super Ring protocol with two ports of commercial switches using RSTP protocol.
An active link where data is transmitted is connected with one port in the switch.
The other port connected with another switch is a hot standby link.
Constantly monitoring the hot standby link and will switch over in seconds once the active link is disconnected or breaks.
The process of switching the backup route from one switch to another is transparent to the user.
The JetNet 4500 also supports SNMP and RMON, compatible with network management software such as IntraVue.
The JetNet 4500 Series includes the JetNet 4508, an eight-port copper device, and the JetNet 4508f, with six copper ports and two fibre ports.
