Recovering a Switch
A switch can become inoperable or unavailable 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 do the following:
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
Reset the switch
To recover a switch, do the following:
1. Place the switch in maintenance mode. Do the following:
a. Power down the switch.
b. Press and hold the Maintenance button with a pointed tool, then power
up the switch. All chassis LEDs will illuminate, then extinguish leaving
only the Input Power LED illuminated. Release the button.
2. Allow one minute for the switch to complete its tests. When the switch is in
maintenance mode, the Input LED will be illuminated and the Heartbeat LED
will illuminate continuously. All other chassis LEDs will be extinguished.
3. Establish a Telnet session with the switch using the maintenance mode IP
address 10.0.0.1.
4. Enter the maintenance mode account name and password (prom, prom),
and press the Enter key.
