CAUTION
Setting the boot PROM password requires accessing the boot prompt, which stops traffic flow
through the switch until the switch is rebooted. Perform this procedure during a planned
downtime.
Setting the boot PROM password for a switch with 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
Supported hardware and software on page 23. If
your switch is not listed, contact your switch support provider for instructions.
1. Connect to the serial port interface as described in Connecting to Fabric OS through the serial port
on page 38.
2. Reboot the switch.
3. Press Esc within four seconds after the message "Press escape within 4 seconds..." is displayed.
4. When prompted, enter 2 to select the recovery password option.
• If no password was previously set, the following message is displayed:
Recovery password is NOT set. Please set it now.
• If a password was previously set, the following messages is displayed:
Send the following string to Customer Support for password recovery:
afHTpyLsDo1Pz0Pk5GzhIw==
Enter the supplied recovery password.
Recovery Password:
5. Enter the recovery password (string).
The recovery string must be from 8 through 40 alphanumeric characters in length. A random string
that is 15 characters or longer is recommended for higher security. The firmware prompts for this
password only 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:
6. Enter the boot PROM password, and then re-enter it when prompted. The password must be eight
alphanumeric characters long (any additional characters are not recorded). Record this password for
future use.
The new password is automatically saved.
7. Reboot the switch by entering the reset command at the prompt.
Setting the boot PROM password for a Backbone with a recovery string
This procedure applies to the Brocade DCX, DCX-4S, DCX 8510-4, and DCX 8510-8 Backbones. The
boot PROM and recovery passwords must be set for each CP blade.
1. Connect to the serial port interface on the standby CP blade, as described in Connecting to Fabric
OS through the serial port on page 38.
2. Connect to the active CP blade over a serial or Telnet connection and enter the haDisable command
to prevent failover during the remaining steps.
