Advertised Ability (Selectable)
During auto-negotiation, the FE-100TX “tells” the device at the other end
of the segment what its capabilities are. 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 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. Section 5.19.4 describes
how to enable or disable advertised modes.
5.19.1 Configuring an FE-100FX/F3 Interface or a Port 7
or 8 FE-100FX/F3 Interface
Whether configuring the fixed interface (ports 1-6) or an FE-100FX or
FE-100F3 installed in port 7 or 8, the procedure is the same. The interface
port must be 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 FE-100FX or FE-100F3 interface ports. 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.
