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 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.
