9.3.5Link 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 ML1200 Managed Field Switch can compensate for situations where only the switch receiver fiber cable is broken. Upon detection of the broken receiver link, the ML1200 will cease sending link pulses through the relay’s receive fiber cable, thereby allowing the relay to switch to its secondary path.
