If the switch does not contain a port trunk, all of the ports on the switch
are unchecked. If there is a port trunk, the ports in the trunk are
checked.

Trunk 7 is reserved for ports 17 and 18 on the AT-FS750/16 and
ports 25 and 26 on the AT-FS750/24.
3. In any one of the unused Trunk ID rows, click the dialog boxes of the
ports that will make up the port trunk. A check in a box indicates the

member. A port trunk can contain up to eight ports.
4. Change the status of the trunk from Disable to Enable.
5. Click Apply.
The trunk is now operational on the switch.
6. Configure the port trunk on the other switch and connect the cables.
