9.3.5 Link Loss Alert
The GE Multilin Universal Relay (UR) family and the F650 family of relays have redundant
Ethernet ports that allow for automatic switching to their secondary ports when they
detect the primary path is broken. The MultiLink switches can compensate for situations
where only the switch receiver fiber cable is broken. Upon detection of the broken receiver
link, the ML3000 will cease sending link pulses through the relay’s receive fiber cable,
thereby allowing the relay to switch to its secondary path.
