The boot PROM password
5
• If a password was previously set, the following messages are displayed:
Send the following string to Customer Support for password recovery:
afHTpyLsDo1Pz0Pk5GzhIw==
Enter the supplied recovery password.
Recovery Password:
6. Enter the recovery password (string).
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 is displayed:
New password:
7. Enter the boot PROM password, and then reenter it when prompted. The password must be
eight alphanumeric characters (any additional characters are not recorded). Record this
password for future use.
The new password is automatically saved (the saveEnv command is not required).
8. Connect to the active CP blade over a serial or Telnet connection and enter the haEnable
command to restore high availability, and then fail over the active CP blade by entering the
haFailover command.
Traffic flow through the active CP blade resumes when the failover is complete.
9. Connect the serial cable to the serial port on the new standby CP blade (previously the active
CP blade).
10. Repeat step 2 through step 7 for the new standby CP blade (each CP blade has a separate
boot PROM password).
11. Connect to the active CP blade over a serial or Telnet connection and enter the haEnable
command to restore high availability.
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
“Setting the boot
PROM password for a switch with a recovery string” on page 145. 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.
Setting the boot PROM password for a switch without a recovery string
This procedure applies to the fixed-port switch models.
The password recovery instructions provided within this section are only for the switches listed in
the Preface. If your switch is not listed, contact your switch support provider for instructions.
1. Create a serial connection to the switch as described in “Connecting to Fabric OS through the
serial port” on page 56.
2. Reboot the switch by entering the reboot command.
3. Press Esc within four seconds after the message “Press escape within 4 seconds...” is
displayed.
