Recovering a switch using maintenance mode
A switch can become inoperable or unmanageable for the following reasons:
• Firmware becomes corrupt
• IP address is lost
• Switch configuration becomes corrupt
• Password is forgotten
In these specific cases, you can recover the switch using maintenance mode. Maintenance mode
temporarily returns the switch IP address to 10.0.0.1 and provides opportunities to do the following:
• Exiting the maintenance menu (option 0), page 55
• Unpacking a firmware image file in maintenance mode (option 1), page 56
• Resetting the network configuration in maintenance mode (option 2), page 56
