Recovery from the loader> Prompt
Use the help command at the loader> prompt to display a list of commands available at this prompt or to
obtain more information about a specific command in that list.
Before You Begin
This procedure uses the init system command, which reformats the file system of the device. Be sure that
you have made a backup of the configuration files before you begin this procedure.
The loader> prompt is different from the regular switch# or switch(boot)# prompt. The CLI command
completion feature does not work at the loader> prompt and might result in undesired errors. You must type
the command exactly as you want the command to appear.
If you boot over TFTP from the loader> prompt, you must supply the full path to the image on the remote
server.

Description
When the boot loader phase is over, press
Ctrl-] (Control key plus right bracket key)
to enter the switch(boot)# prompt. Depending
on your Telnet client, these keys might be
reserved, and you might need to remap the
keystroke. See the documentation provided
by your Telnet client. If the corruption causes
the console to stop at this prompt, copy the
nx-os image and reboot the system.
The nx-os image then loads the configuration
file of the last saved running configuration
and returns a switch login prompt.
