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

„Unpacking a Firmware Image File in Maintenance Mode

„Resetting the Network Configuration in Maintenance Mode

„Resetting User Accounts in Maintenance Mode

„Copying Log Files in Maintenance Mode

„Removing the Switch Configuration in Maintenance Mode

„Remaking the File System in Maintenance Mode

„Resetting the Switch in Maintenance Mode

„Updating the Boot Loader in Maintenance Mode

To recover a switch, do the following:

1.Place the switch in maintenance mode. Press and hold the Maintenance button with a pointed tool until the Heartbeat LED alone is illuminated, then release the button. The Heartbeat LED illuminates continuously when the switch is in maintenance mode.

2.Establish a Telnet session with the switch using the maintenance mode IP address 10.0.0.1.

3.Enter the maintenance mode account name and password (prom, prom), and press the Enter key.
