Solving Problems
With Quick Config
Manager
You cannot access the hub over a serial connection for the first
time.
There may be a number of reasons for this:
■
For a successful local management connection, you need to use a
standard null modem cable, and have the hub’s console port set to
9600 baud or auto-configuration enabled. These are the default
settings. For information on the console port settings, refer to
“Changing the Console Port Settings” on page B-27.
■
It may be that you have made your management connection to a
serial port, on your management station, which is not the port
Quick Config Manager is using. Quick Config Manager uses COM1
as the default serial port. For information on changing this, refer to
“Running Quick Config Manager” on page B-4.
■
When using Quick Config Manager with Windows ‘95 and
managing through the console port, you must first disable FIFO
buffers in the Advanced Port Settings window in Windows ‘95.
For information on doing this, refer to “Through the Console Port”
on page 5-13.
■
There may be another application running on your management
station, that is using the management station’s serial (COM) port,
for example HyperTerminal.
