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 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 (or user) 
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
When an FE-100FX or FE-100F3 is installed, 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.
NOTE
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.
