10.For a hub stack with a master present, you must configure the software for the installed bridge module to enable the internal bridge function because the software default setting is disabled. The default software setting will not allow the internal bridge function to enable. The software must be configured using a master hub.

11.Start a Console or Web-Based Management session and set the software configuration for the new module. For information on starting a console session, refer to Chapter 4: Console Management. For information on Bridge Module configuration, refer to Chapter 4: Console Management: Controlling Devices.
