2.  Connect the other end of the cable to the LAN. 
3.  For 1+1 LAN protection, repeat steps 1 and 2 for the standby port, but connect it to 
another network (in the same subnet). 
 
 
Note: If you are implementing LAN port-pair redundancy, make sure that each port in the 
Ethernet Group is connected to a different network (in the same subnet).
