To recover the password for the IDSM2, you must install a special password recovery image file. This 
installation only resets the password, all other configuration remains intact. The password recovery 
image is version-dependent and can be found on the Cisco Download Software site. For IPS 6.x, 
download WS-SVC-IDSM2-K9-a-6.0-password-recovery.bin.gz. For IPS 7.x, download 
WS-SVC-IDSM2-K9-a-7.0-password-recovery.bin.gz.

FTP is the only supported protocol for image installations, so make sure you put the password recovery 
image file on an FTP server that is accessible to the switch. You must have administrative access to the 
Cisco 6500 series switch to recover the password on the IDSM2.

During the password recovery image installation, the following message appears:

Upgrading will wipe out the contents on the hard disk.

Do you want to proceed installing it [y|n]:

This message is in error. Installing the password recovery image does not remove any configuration, it 
only resets the login account.

Once you have downloaded the password recovery image file, follow the instructions to install the 
system image file but substitute the password recovery image file for the system image file. The IDSM2 
should reboot into the primary partition after installing the recovery image file. If it does not, enter the 
following command from the switch:

The password is reset to cisco. Log in to the CLI with username cisco and password cisco. You can then 
change the password.

For the procedures for reimaging the IDSM2, refer to
