Auto-recovery feature offers speed and reliability
Ethernet Direct's X-ring can deactivate one of the links in the ring to data traffic while simultaneously monitoring that the link is functioning.
Industrial Ethernet switches span all applications
The Husky switch product line offers a complete range of robust industrial Ethernet switches from unmanaged to web-smart and fully managed SNMP switches in both Fast Ethernet and Gigabit versions.
Industrial switches keep gigabit networks up
Husky Series HMG-825 and HMG-826 managed industrial Gigabit Ethernet switches have many management features that help to keep networks intact.
Ethernet Direct's switches deliver the highest accessibility to ensure profitability.
HUE unmanaged switches, HWE web-managed switches, HME managed SNMP Ethernet switches and HMG SNMP Managed Gigabit switches are all equipped with power redundancy, allowing a network to hook up to an alternative power supply if a power failure occurs.
The relay output function will trigger an alarm.
Ring redundancy provides a back-up path in an event that any part of a network is disrupted.
Ethernet Direct's X-Ring is designed for mission critical Industrial networks and can de-activate one of the links in the ring to data traffic while simultaneously monitoring that the link is functioning.
In case one of the links in the ring fails, the de-activated link is activated in less than 300ms for HWE and HME industrial Ethernet switches and less than 30ms for industrial Gigabit switches.
Finding ways to provide recovery from faults in nodes connected to critical devices has been made easy by Ethernet Direct.
Further to ring redundancy, switches should be able to be configured with dual network nodes in the form of dual homing technology.
This network node redundancy adds reliability by allowing a device to be connected to the Ethernet network by having two independent connection points - one as an operating connection and the other as a back-up connection.
This feature is present in Ethernet Direct's Managed SNMP industrial Ethernet and Gigabit switches.
System redundancy is only reliable only when multiple levels of redundancies can be achieved.
It minimises data loss by providing fast recovery time in the event of unexpected network disruption.
