Software Update Utility Problems
An error occurs when the Software Update 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.
Also ensure that the serial cable which you are using is a fully wired
cable with handshaking signals. The Software Update utility only works
with this type of serial cable. The cable which you use to manage the
Switch through the terminal may not have handshaking signals and
may therefore not be compatible with the upgrade utility. Refer to the
PC-AT Serial Cable pin-out diagram in Appendix B of the Getting
Started Guide that accompanies your Switch.
An error occurs when the Software Update 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 Software Update utility attempts to
open the management software file for reading.
There could be two reasons for this:
The file specified in the Software update command does not exist
or is in a 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).
An error occurs when the Software Update utility attempts to
transfer the file.
There could be a number of reasons for this:
The null modem cable has become disconnected from the Switch
or the PC during the file transfer. Reconnect the cable and start
again.
Power to the Switch has been disrupted during the file transfer.
Check the power connection to the Switch and start again.
