Setting the boot PROM password 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 ”Setting the boot PROM
password with a recovery string” on page 79. 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 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.

The password recovery instructions contained within this section are only for the switches listed in the title.
If your switch is not listed, contact HP for instructions.
To set the boot PROM password for a switch without a recovery string:
1. Create a serial connection to the switch.
2. Enter the reboot command to reset the switch.
3. Press ESC within four seconds after the message “Press escape within 4 seconds...” displays.
The following options are available:
4. Enter 3.
5. At the shell prompt, enter the passwd command.
NOTE: The passwd command only applies to the boot PROM password when it is entered from the boot
interface.
6. Enter your boot PROM password at the prompt, then re-enter it when prompted. The password must be
eight alphanumeric characters (any additional characters are not recorded). Record this password for
future use.
7. Enter the saveEnv command to save the new password.
8. Enter the reboot command to reset the switch.
4/256 SAN Director and DC SAN Backbone Director (short name, DC Director)
On 4/256 SAN Director and DC Director models, set the password on the standby CP blade, fail over,
and then set the password on the previously active (now standby) CP blade to minimize disruption to the
fabric.
To set the boot PROM password for a Director without a recovery string:
1. Determine the active CP blade by opening a Telnet session to either CP blade, connecting as admin,
and entering the haShow command.
2. Connect to the active CP blade by serial or Telnet and enter the haDisable command to prevent
failover during the remaining steps.
3. Create a serial connection to the standby CP blade.
4. Reboot the standby CP blade by sliding the On/Off switch on the ejector handle of the standby CP
blade to Off, and then back to On.
This causes the blade to reset.
5. Press ESC within four seconds after the message
Press escape within 4 seconds... displays.
