Designed for the Needs of Protection Relaying
The MultiLink Ethernet Switches have been designed for the specific
requirements of devices used in Utility and Industrial environments such
as Protection Relays. MultiLink Switches support many unique features
that allow for full redundancy under network fault conditions.
Link Loss Alert
The MultiLink Switch's Link Loss Alert feature allows for Protective
Relays to recover from situations where only one of the fiber cables
connected to the relay is damaged. The Link Loss Alert feature works
with both 10Mbit and 100Mbit fiber ports of GE Multilin's Universal
Relay, and allows for seamless switching to the relay's secondary port
under all network fault conditions.
Link Loss Alert allows recovery from a broken fiber connection in
both 10Mbit and 100Mbit applications
