5.11.2 Setting the FE-100TX Operational Mode
Use this field to set the active technology. This field steps to
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 displays in both the
Desired Oper. Mode field and the Current Oper. Mode field.
5.11.3 Setting the FE-100TX Advertised Ability
During normal operation, ports 1 through 6 and optionally in port 7 or 8
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 to 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 Advertised Ability field.
2. Use the SPACE bar to select the desired mode.
3. Use the LEFT-ARROW key to move back to the Advertised Ability
selection and use the SPACE bar to select the next mode to enable or
disable.
4. Use the RIGHT-ARROW key to move across to the
Enabled/Disabled field to the right of the selection.
5. Use the SPACE bar to select Enabled or Disabled. Press ENTER.
Continue this process until you have completed enabling or disabling
the advertised modes.
