Advertised Ability (Selectable)
During auto-negotiation, the FE-100TX informs the device at the other 
end of the segment about its capabilities. The capabilities of a port (25 or 
26) 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.

Configuring an FE-100FX or FE-100F3

manually set to operate in the same technology as the device at the other 
end of the connected segment.

Use the Desired Oper. Mode field to set the active technology. This field 
toggles between 100Base-FX and 100Base-FXFD (full duplex). To set the 
active technology through Local Management, proceed as follows:
1.
Use the arrow keys to highlight the Desired Oper. Mode field.
2.
Use the SPACE bar to select 100Base-FX or 100Base-FXFD (full 
duplex). 
3.
Press ENTER. The port now operates in the chosen mode. 
4.
Use the arrow keys to highlight the SAVE command. Press ENTER. 
The message “SAVED OK” displays and Local Management saves 
the changes to memory.
