There may be a number of reasons for this:n For a successful local management connection, you need to use astandard null modem cable, and have the hub’s console port set to9600 baud or auto-configuration enabled. These are the defaultsettings. For information on the console port settings, refer to“Changing the Console Port Settings” on page B-27.n It may be that you have made your management connection to aserial port, on your management station, which is not the portQuick Config Manager is using.
