4.2.6 Loop Prevention
The EMS5-8MA-SWITCH supports loop prevention function that can detect and relieve a loop situation of
Ethernet network topology. As long as loop condition is detected, the switch blocks the port automatically and
starts to blink the port Link/Act LED to indicate which port has been blocked to relieve a loop. When a loop
condition disappears, the port Link/Act LED returns to normal port property state automatically.
