NM_ETH1: 
 
Connects the network 
interface on the 
equipment through a 
network cable to that on 
an NM server so that the 
NM can manage the 
equipment. 
 
Connects the 
NM_ETH1/NM_ETH2 
network interface on one 
NE through a network 
cable to that on another 
NE to achieve 
communication between 
NEs. 
ETH1-ETH3: 
 
Connects a network 
cable from the 
ETH1/ETH2/ETH3 
interface on one subrack 
to corresponding 
interfaces on the other 
subracks to achieve the 
communication between 
the master subrack and 
slave subracks.
