Advertised Ability (Selectable)
During auto-negotiation, the FE-100TX informs 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 5.11.4 describes
how to enable or disable advertised modes.
5.11.1 Configuring an FE-100FX 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 port
must be manually set to operate in the same mode 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 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.
5.11.2 Configuring an FE-100TX Interface
In normal operation, a port with an FE-100TX interface automatically
establishes a link with the device at the other end of the segment and no
user setup is required.
Section 5.11.3 and Section 5.11.4 provide
instructions to manually configure the port with an FE-100TX installed.
