Cabletron Systems 2H28-08R Manual Do Utilizador

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:

Use the arrow keys to highlight the Desired Oper. Mode field.

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. 

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.

During normal operation, a port (7 or 8) 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:

Use the arrow keys to highlight the Advertised Ability field.

Use the SPACE bar to select the desired mode. 

Use the RIGHT-ARROW key to move across to the 
ENABLED/DISABLED field to the right of the selection. 

Use the SPACE bar to select ENABLED or DISABLED. Press 
ENTER. 

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.
