Chapter 5: Local Management

If an FE-100TX is installed, the field steps to Auto-Negotiation, 
10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD 
(full duplex). In normal operation, the port with an FE-100TX installed is 
capable of auto-negotiating the operational mode and no further user 
setup is required. 

 describes how to manually configure an 

FE-100TX.

In Auto Negotiation, the FE-100TX negotiates to the highest common 
denominator of the two interfaces. The order of priority of negotiation is 
100Base-TXFD, 100Base-TX, 10Base-TFD, and 10Base-T.

Advertised Ability (Selectable)

During auto-negotiation, the FE-100TX “tells” the device at the other end 
of the segment about its capabilities. The capabilities of a port (5 or 6) 
with an FE-100TX installed are 10Base-T, 10Base-TFD (full duplex 
mode), 100Base-TX and 100Base-TXFD (full duplex mode). In normal 
operation, with all capabilities enabled, the FE-100TX “advertises” that it 
has the ability to operate in any mode. The Network Manager may choose 
to set up the port so that only a portion of the available capabilities are 
advertised and the others are disabled. For example, only 100Base-TX 
and 100Base-TXFD might be enabled so that only devices that operate at 
100 Mbps can communicate with that port. 

 describes 

how to enable or disable advertised modes.

When an FE-100FX or FE-100F3 is installed in port 5 or 6, it must be 
manually set to operate in the same technology as the device at the other 
end of the connected segment. 

 provides instructions for 

manually configuring the port with an FE-100FX or FE-100F3 interface.

In normal operation, the port with an FE-100TX installed 
automatically establishes a link with the device at the other end 
of the segment without requiring user setup. However, Local 
Management provides the user with the option of manually 
configuring that port.
