How can I change password for 3com 3c17300 superstack switch?

I have a 3com 3c17300 superstack switch and I have lost the password.  Is there a way I can wipe the information and give the the switch a new password?

Thanks.

I read on some of their switches enter    recover   as the login name and leave password blank. Then perform a "hard reset" within 30 seconds. It will reboot in password recovery mode and you can enter a new admin password. This is not supposed to change the device configuration, but rather just allow you to set a new password.

SuperStack 3 Switch 4200/4300/4400/4900/ SS3 Webcache - How to recover from a Lost password

Symptom
Forgot the password for the "admin" user account and can no longer perform important management
operations.

Cause I
If you forget your password, for the admin user account, but have other "Security" user accounts set up on your unit, you are able to reset the Admin password. The following Password Recovery allows you to define a new password for the admin account, even though you have forgotten the current one.

Fix
If you have added any additional users with "Security" access level each additional user can modify all passwords on the unit. Should any password become lost, a user with Security access level must log into a unit via the Command Line Interface and change the password of the user account in question. Use the "security > device > user > modify" command to do this.

NOTE: You can modify user details for the entire stack using the modify command on the User menu.
NOTE: A user's access level cannot be modified

To modify user 'admin' details for the stack:

1. Login to the unit as 'security' or admin equivalent user. From the Top-level menu, enter: security device user modify. The following prompt is displayed: Enter the user name
2. Enter the name of the user 'admin'. The following prompt is displayed: Enter the password:
3. Enter a new password for the user. The following prompt is displayed: Re-enter the password:
4. Enter the password for the user again. The following prompt is displayed: Enter the community string
[<user>]:
5. Enter a community string "private" for the user "admin".
6. Verify the user accounts are correct by entering the command "summary". The table displayed will list all user accounts showing security level and community string. NOTE the passwords are not displayed.

Cause II
If you forget your password, for the admin user account, and have no other "Security" user accounts set up on your unit, you will no longer be able to perform important security management operations on that unit. The following Password Recovery allows you to define a new password for the admin account, even though you have forgotten the current one.

Fix
Should there be no Security level logins (including "Admin") available on the unit, you must use the password recovery method outlined below, to define a new password for the "admin" user account:
NOTE: Password recovery can be enabled or disabled at any time through the CLI, by accessing the CLI and using the security > device > user > pwdRecover command.
CAUTION: If you disable Password Recovery for a Switch and subsequently forget the password for the "admin" user account, you will have to return the Switch to 3Com.
NOTE: If your product has a Redundant Power Supply (RPS) connected, you will need to disconnect it in order to perform a hard reset.
NOTE: You cannot use a soft reset operation to reset the password of the "admin" user account. This will end the password recovery procedure and return you to the CLI login prompt.
NOTE: You cannot use a soft reset operation to reset the password of the "admin" user account. This will end the password recovery procedure and return you to the CLI login prompt.
NOTE: Password recovery cannot be performed via a SLIP (Serial Line Internet Protocol) connection.

Use the password recovery method outlined below to define a new password for the admin username:

1.Access the Command Line Interface and enter the user name "recover" and password "recover" to place your unit in password recovery mode. The unit will remain in password recovery mode for a maximum of 30 seconds, before it returns to the CLI login prompt.
2. During the 30 seconds, perform a hard reset on the unit while the it is still in password recovery mode by switching it off, waiting a few seconds, and switching it on again.
3. When the unit has rebooted following the hard reset enter a new password for the "admin" user account.
4. Enter enable to leave password recovery enabled, or enter disable to turn it off. You are now logged in as the default "admin" user.

Thanks RobWill and afurman for your replys.

I was able to get into the switch and reset the password.  I needed to put recover in both the login and password.
