Attempting to reset CP cards to Factory Defaults on Silkworm 24000

We have two CP cards in a Silkworm 24000 that we are trying to reset to factory defaults.  The root passwords are not available.  In the directions I found elsewhere:

To obtain the Boot PROM recovery password from your switch support provider:

1. Connect to the serial port interface of the switch or standby CP.

2. Reboot the switch or standby CP.

3. Press ESC within four seconds after the message “Press escape within 4 seconds...”.

4. Enter 2 at the prompt. A character string is displayed.

5. Send the character string to your switch support provider to obtain a Boot PROM recovery password.

6. Perform the appropriate steps to set the Boot PROM password if it was not set, as prompted:

The message "Press escape within 4 seconds..." never shows up.  I have attempted to log in via the root, admin, factory and user accounts with the default passwords with no luck. Even removed the battery on the CP cards hoping it would clear out the settings.


Any suggestions on regaining control of the cards would be greatly appreciated.

Thanks!

Niel

Obtaining the boot PROM recovery password

NOTE

This procedure is for obtaining a BOOT PROM recovery password. This does not reset the Fabric OS

passwords on the switch. Once the Boot PROM password has been recovered, you must go through

the boot prom command shell to reset the Fabric OS passwords on the switch.

This section explains how to gather the information you need to send to your switch support

provider in order to get a Boot PROM recovery password. Once you have received the Boot PROM

recovery password, and gained access to the Boot PROM, you reset the passwords using

“Password recovery using the boot PROM interface” on page 2.

To obtain the Boot PROM recovery password from your switch support provider:

1. Connect to the serial port interface of the switch or standby CP.

2. Reboot the switch or standby CP.

3. Press ESC within four seconds after the message “Press escape within 4 seconds...”.

4. Enter 2 at the prompt. A character string is displayed.

5. Send the character string to your switch support provider to obtain a Boot PROM recovery

password.

1) Start system.

2) Recover password.

3) Enter command shell.

Option? 2

Send the following string to Customer Support for password recovery:

/uasLR1raCqT3FToqy0ZjA==

6. Perform the appropriate steps to set the Boot PROM password if it was not set, as prompted:

Recovery password is NOT set. Please set it now.

7. Enter the Recovery Password that is generated from your support provider when prompted.

8. When prompted with “New password:”, enter the new Boot PROM password and re-enter when

prompted.

9. Record the new password for future reference.

10. Enter the saveenv command.

Follow the steps to recoever a complete recovery entry. The output is related to the steps above

as well.

Enter resetpw command (to clear boot ROM password usage)

Then run saveenv command. Passwords will no longer be required for boot ROM access.

Enter the supplied recovery password.

Recovery Password: YnfG9DDrlFMDVkNM0RkPtg== < Supplied by your support

provider

Re-enter Recovery Password: YnfG9DDrlFMDVkNM0RkPtg==

New password: xxx

Re-enter new password: xxx

> saveenv
