PLANET Desktop Switch 

Loop Isolation 

Loop Isolation is an important feature of the Desktop Switch FSD-1020, 
supported 

only if

 the memory expansion module FSD-MAC is installed. This 

condition could exist if two ports are inadvertently connected to each other 
causing a loop. 

 

Figure 3.12 Loop Condition. 

The switching device can not sustain a loop because it produces Broadcast 
Storm thereby jamming the system with looping packets. Desktop Switch 
FSD-1020 supports isolating the looped ports. If the function is enabled, the 
device will monitor all ports to see if there are any loops. 
 
Once a loop is detected, it will disable any one of the two ports. The port 
number outline-frame will blink indicating it has been temporarily isolated. 
Every 10 minutes, the port will be released to see if it is still looping. 
 
The function of LOOP ISOLATE is disabled at the time it shipped from 
manufacturer. You have to enable the function through Mini-Console. The 
command sequence is: 
 

UNIT CONFIG > LOOP ISOLATE > ENABLE><Enter and hold> 

 

After the command is entered, it will be saved in the EEPROM.
