Utility Problems
An error occurs when the utility attempts to connect through the
serial port of the PC.
The serial port being used is not the same as the
serial port specified in the upgrade command. Retry the command
ensuring that you specify a value of ‘1’ or ‘2’ for the serial port.
An error occurs when the utility attempts to communicate with
the Switch.
There could be a number of reasons for this:
■
The Switch is not being powered-up within 5 seconds of pressing
[Return].
■
The null modem cable is not connected to the console port of the
Switch.
■
The null modem cable is not connected to the serial port of the PC, or,
the serial port being used is not the same as the serial port specified in
the upgrade command.
■
The Switch is not being powered-down and up as directed.
Retry the command ensuring that you follow all the steps.
An error occurs when the utility attempts to open the
management software file for reading.
There could be two reasons
for this:

different directory to the one given. Check the filename and its
location.
■
You do not have read access for the file. Check the properties of the
file using Explorer (in Windows ’95) or File Manager (in other versions
of Windows).
The error message
USAGE: update [-c comport] filename
is
displayed.
