Setting the Boot PROM Password
3
If a password was previously set, the following messages display:
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 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 use.
The new password is automatically saved (the saveEnv command is not required).
8. Connect to the active CP blade by serial or telnet and enter the haEnable command to restore high
availability; 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 by serial or telnet and enter the haEnable command to restore
high availability.
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 “With a Recovery String” on
page 3-35. 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.
SilkWorm 200E, 3250, 3850, 3900, 4012, and 4100
Follow this procedure to set the boot PROM password without a recovery string:
Send the following string to Customer Support for password recovery:

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.
