Chapter 5 Troubleshooting

Restore Switch Settings

•

Reset the switch to delete the current configuration settings, and then restart
the switch.

Note

Resetting the switch to its factory defaults deletes all customized
switch settings, including the IP address. The same software image is
retained. You will need to reconfigure the basic switch settings (as
described in the Getting Started Guide for the Catalyst Express 500
Switches) and use the new IP address to display the device manager.

Resetting the switch interrupts connectivity of your devices to the
network.

You can only reset the switch through the device manager.

Restore Switch Settings

You can restore your configuration settings by using Network Assistant to save the
switch configuration file. After saving the configuration file, you must use the
device manager Restart / Reset window to reset the switch. After resetting the
switch, use the Express Setup window to assign a switch IP address and to assign
the same host name that was used before the switch was reset. Then you can load
the configuration file to the switch and restore the previous configuration settings.
For information about saving configuration files, see the Network Assistant
documentation.

Upgrade the Switch Software

Prerequisite

You must have access to the Internet to download switch software from Cisco.com
to your PC or network drive.

Use the Software Upgrade window (

Figure 5-3

) to update the switch with the

latest software changes (such as software patches) and features. To display this
window, choose Software Upgrade from the device manager menu.
