Use this method when the device cannot start
up correctly.
To use this method, first connect to the console
port and power cycle the device. Then press
Ctrl+B
at prompt to access the BootWare
menu.
IMPORTANT:
Upgrade an IRF system from the CLI instead of
the BootWare menu, if possible.
The BootWare menu method increases the
service downtime, because it requires that you
upgrade the member devices one by one.
