A switch can become inoperable or unmanageable for the following reasons:

Corrupt firmware

Lost IP address


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 access to the following menu options:

Exiting the Maintenance Menu (Option 0)

Unpacking a Firmware Image File in Maintenance Mode (Option 1)

Maintenance button with a pointed tool until only the Heartbeat LED is lit,
and then release the button.

address 10.0.0.1.
3. Type the maintenance mode account name ( prom ) and password ( prom ).
