Booting the N30xx Switch
When the power is turned on with the local terminal already connected, the
switch goes through a power-on self-test (POST). POST runs every time the
switch is initialized and checks hardware components to determine if the
switch is fully operational before completely booting. If POST detects a
critical problem, the program flow stops. If POST passes successfully, valid
firmware is loaded into RAM. POST messages are displayed on the terminal
and indicate test success or failure. The boot process runs for approximately
60 seconds.
You can invoke the Boot menu after the first part of the POST is completed.
From the Boot menu, you can perform configuration tasks such as resetting
the system to factory defaults, activating the backup image, or recovering a
password. For more information about the Boot menu functions, see the CLI
Reference Guide.
