Upgrade the Switch Software
Troubleshoot a Failed Software Upgrade
If the upgrade process does not complete or if the switch fails to restart after the
upgrade process completes, follow these steps:
1. Make sure that you downloaded the correct tar file from Cisco.com.
2. If you downloaded the correct tar file, refresh your device manager browser
session to make sure that there is connectivity between the switch and your
PC or network drive.
3. Try to upgrade the switch again by following the procedures in the “Upgrade
the Switch Software” section on page 5-5.
If the upgrade process fails again, follow these steps:
1. Select the Reset the switch to factory defaults option on the Restart / Reset
window, and then click Submit.
Resetting the switch to its factory defaults deletes all customized switch
settings, including the IP address.
2. Reconfigure the switch settings, including assigning an IP address to the
switch, as described in the Getting Started Guide for the Catalyst Express 500
Switches.
3. Use the new switch IP address to display the device manager.
4. Try to upgrade the switch again by following the procedures in the “Upgrade
the Switch Software” section on page 5-5.
If the upgrade process still fails (for example, an
Upgrade Failed message
appears or the System LED does not turn solid green after a few seconds), follow
the procedures in the “Recover the Switch Software” section on page 5-9.
Upgrade to a Noncryptographic Software Version
You can upgrade the switch from a cryptographic version of the switch software
to a noncryptographic version. However, the device manager cannot automatically
redisplay after the software upgrade completes if the switch was previously
running the cryptographic version and if the device manager was accessed
through a secured session. Close the existing browser session with the device
manager. Then open a new browser session, and enter http://
before the switch IP
address.
