The recovery string must be between 8 and 40 alphanumeric characters. A random string that is 15
characters or longer is recommended for higher security. The firmware only prompts for this password
once. It is not necessary to remember the recovery string because it is displayed the next time you enter
the command shell.
The following prompt displays:
7. Enter the boot PROM password; then reenter it when prompted. The password must be eight
alphanumeric characters (any additional characters are not recorded). Record this password for future

How to set the boot PROM password for a Director without a recovery string
Although you can set the boot PROM password without also setting the recovery string, it is strongly
recommended that you set both the password and the string as described in ”Without a Recovery String”
on page 114. If your site procedures dictate that you must set the boot PROM password without the string,
follow the procedure that applies to your switch model.
NOTE: Setting the boot PROM password requires accessing the boot prompt, which stops traffic flow
through the switch until the switch is rebooted. You should perform this procedure during a planned down
time.
