Chapter 7 Troubleshooting the Switch

Troubleshoot a Failed Software Upgrade

Troubleshoot a Failed Software Upgrade

If you attempted to upgrade the switch software but received a message that the upgrade failed, make sure that you still have access to the switch. If you still have switch access, follow these steps:

Step 1 Make sure that you downloaded the correct tar file from Cisco.com.

Step 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 laptop or network drive.

Step 3 Try to upgrade the switch again by following the procedures in the Cisco Configuration Assistant online help.

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 procedure in the “Recover the Switch Software” section on page 7-10.

If You Need Further Help

We strongly recommend that you download the Cisco Configuration Assistant from Cisco.com and use the enhanced set of tools to troubleshoot the switch and your network. You can download it from this Cisco.com site:

Use the monitoring features from the device manager as described in Chapter 6, “Monitoring the Switch.”
