5.22.3 Configuring an FE-100TX in Port 25 or 26
In normal operation, a port (25 or 26) 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 5.22.4 and Section 5.22.5
provide instructions for manually configuring the port with an FE-100TX
installed.
5.22.4 Setting the FE-100TX Operational Mode
Use this field to set the active technology. This field steps between
Auto-Negotiation, 10BASE-T, 10BASE-TFD (full duplex),
100BASE-TX, and 100BASE-TXFD (full duplex). If Auto-Negotiation is
selected, the FE-100TX automatically sets the active technology. To
manually 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 the desired mode. Press ENTER. If any
mode other than Auto-Negotiation is selected, the port only operates
in the chosen mode and auto-negotiation is disabled.
3. Use the arrow keys to highlight the SAVE command. Press ENTER.
The message “SAVED OK” displays and Local Management saves
the changes to memory. The selected mode is displayed in both the
Desired Operational Mode field and the Current Operational Mode
field.
5.22.5 Setting the FE-100TX Advertised Ability
In normal operation, a port (25 or 26) with an FE-100TX auto-negotiates
to the highest speed possible. Under some circumstances, the Network
Administrator may want the port to advertise only some of the available
modes and not operate in other modes. This field steps between
10BASE-T, 10BASE-TFD (full duplex), 100BASE-TX, and
100BASE-TXFD (full duplex). To set the advertised ability, proceed as
follows:
1. Use the arrow keys to highlight the Desired Oper. Mode field.
2. Use the SPACE bar to select the desired mode.
