4.2.1.1Setting the Operational Mode

Use the Desired Oper. Mode field to set the active technology. This field steps between Auto-Negotiationand 1000Base-XFD. If Auto-Negotiation is selected, the HSIM-G automatically sets the active technology to auto-negotiate with another 802.3z compliant device. 1000Base-XFD must be chosen if the device on the other side of the link does not support Auto-Negotiation.

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. You may select Auto-Negotiationor 1000Base-XFD. If 1000Base-XFD is selected, the port only operates in 1000Base-XFD 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.

4.2.1.2Setting the Advertised Ability

The HSIM-G auto-negotiates using 1000BaseXFD with an 802.3z compliant device on the other end of the link. Under certain circumstances (refer to Desired Oper. Mode (Toggle)), the Network Administrator may not want the port to advertise the available mode. To set the advertised ability, proceed as follows:

1.Use the arrow keys to highlight the Enabled/Disabled field to the right of the selection.

2.Use the SPACE bar to select Enabled or Disabled. Press ENTER.

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.
