If you have no luck guessing passwords you can try the following.
Recovering a Lost Administrator Password
If an administrator password is forgotten, lost, or misconfigured, perform the following steps to reset the password on the device.
________________________________________
Note There is no way to restore a lost administrator password. You must reset the password to a new one, as described in this procedure.

Step 1 Establish a console connection to the device and open a terminal session.
Step 2 Reboot the device. While the device is rebooting, watch for the following prompt and press Enter when you see it:
Cisco ACNS boot:hit RETURN to set boot flags:0009
Step 3 When prompted to enter bootflags, enter this value:
0x8000
For example:
Available boot flags (enter the sum of the desired flags):
0x4000 - bypass nvram config
0x8000 - disable login security
[CE boot - enter bootflags]:0x8000
You have entered boot flags = 0x8000
Boot with these flags? [yes]:yes
[Display output omitted]
Setting the configuration flags to 0x8000 lets you into the system, bypassing all
security. Setting the configuration flags field to 0x4000 lets you bypass the NVRAM
configuration.
Step 4 When the device completes the boot sequence, you are prompted to enter the username to access the CLI. Enter the default administrator username (admin):
Cisco Content Engine Console
Username: admin
Step 5 Once you see the CLI prompt, set the password for the user using the username password command in global configuration mode.
The following example shows the different options and parameters for the username command. You can specify that the password be either clear text or encrypted. The user in the example chose to have an encrypted password.
ContentEngine# configure
ContentEngine(config)# username ?
WORD User name
ContentEngine(config)# username biff ?
password Specify the password for the user
privilege Set user privilege level
samba-password Set user's Windows sharing password
ContentEngine(config)# username biff password ?
0 Specifies clear-text password (default)
1 Specifies type 1 encrypted password
WORD User password (clear text)
ContentEngine(config)# username biff password 0 ?
WORD User password (encrypted)
ContentEngine(config)# username biff password 0 mypassword ?
uid User Id
ContentEngine(config)# username biff password 0 mypassword uid ?
<2001-65535> User Id
ContentEngine(config)# username biff password 0 mypassword uid 2001 ?
ContentEngine(config)#
Step 6 Use the write memory command in EXEC mode to save the configuration change.
ContentEngine(config)# exit
ContentEngine# write memory
Step 7 Optionally, reboot your device by using the reload command.
ContentEngine# reload
Rebooting is optional; however, you might want to reboot to ensure that the boot flags are reset, and to ensure that subsequent console administrator logins do not bypass the password check.

Note In ACNS software, the bootflags are reset to 0x0 on every reboot.
