Configuring Ports

The PORT CONFIG menu enables you to configure individual ports or all ports at one time. You are prompted to enter the password when the console is locked. The ports must be configured to match the devices at the other end of the link. Settings such as speed must be identical. All ports are set to default to AUTO NEGO. When the AUTO NEGO mode is set, the highest speed supported by both ends is negotiated by the port and the device at the other end.

In the Port Setting menu, “PORT CONFIG” displays in the message zone and the currently selected hub is indicated by the “group cursor” under the port number indicator, as shown below.
