When an ONline management module is installed in a concentrator, all of the dip switch settings on the 10BASE-FL Module are overridden.

When you first install the module:

1.The network (channel) defaults to isolated mode. The ports are automatically disabled so that unapproved users cannot be added. Therefore, you must enable the ports you wish to use and set the ports to the appropriate Ethernet network through the management commands.

2.All other module settings retain the same default values as the dip switch default values. Therefore, you only need to changes these values through management if you do not want the default values.

This section describes the management commands to set these features. For additional information on the available network management features, refer to:

The appropriate ONline management module installation and operation guide

Enabling Ports

You can enable or disable each of the four ports on the module. When a port is enabled, it can transmit data onto and receive data from the network to which the module is assigned. Disable all unused ports on the 10BASE-FB Modules to prevent the Status indicators from flashing a No Light condition.

To enable or disable a specific port, use the following management command:

SET PORT {slot.port} MODE {enable}

{slot.all} {disable}
