In addition, it allows determination of the management information in regards to it being ‘in-
band’ (carried over the air, and available from both the MAIN and AUX connectors on either 
end of the link) or ‘out-of-band’ (not carried over the air, and only available from the local AUX 
connector. 
 

When in-band management is selected, and there is at least one Ethernet 
connection to the radio (AUX, MAIN, or both), if Ethernet link is absent from 
either connector (leaving only one connected and working) there will 

not

 be an 

alarm indicating that the second connector is not connected and/or linked. Since 
the AUX and MAIN ports are connected through a switch, it is impossible to 
alarm each port individually while in this configuration. 

 
Muting of the MAIN connection may be desirable if connected equipment senses Ethernet 
signaling and makes decisions (such as Spanning Tree Protocol enable) based on the presence or 
lack of presence of the Ethernet signal. If the MAIN connection has muting enabled, the port will 
mute when the link is not active. 
 
It may be desirable to disable the alarming of the AUX connector if you are not using the AUX 
connector. 
 
Depending on the connected equipment, optimum Ethernet performance may be achieved by a 
variety of combinations of speed/duplex settings. That is, the system may perform best if both 
devices (the radio and the connected equipment) are set to auto-negotiate, both hard set to 
100/Full, or one set to 100/Full and the other auto-negotiate. Device performance varies widely. 
Therefore, it can be advantageous to attempt different combinations of settings to determine the 
best combination for your application.
