Booting the 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 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.
The Boot menu is automatically invoked after the first part of the POST is
completed. To enter the Boot menu, select 2 from the menu when prompted.
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.
