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
• Forgotten password
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 perform the following
procedures:
• Unpack a firmware image file.
• Restore the network configuration parameters to the default values.
• Remove all user accounts and restore the admin account name password to the default.
• Copy the log file.
• Restore factory defaults for all but user accounts and zoning.
• Restore all switch configuration parameters to the factory default values (use the Reset Factory
command).
• Reset the switch.
• Update the system boot loader.
To recover a switch,
1. Place the switch in maintenance mode by pressing and holding the Maintenance button with a pointed
tool for 10 seconds. When the Heartbeat LED alone is illuminated, release the button.
When the switch is in maintenance mode, the Heartbeat LED is illuminated continuously. All other
chassis LEDs are extinguished.
2. Enter the maintenance mode IP address 10.0.0.1 to establish a Telnet session with the switch.
3. Enter the maintenance mode account name and password (prom, prom) to display the recovery
options menu.
