specific lab environment. All of the devices used in this document started with
a cleared (default) configuration. If your network is live, make sure that you
understand the potential impact of any command.

Here are the prerequisites for password recovery:
You must be on-site.
The Network Element (NE) must have IP connectivity.
You must have a password recovery cable. If you do not have a
password recovery cable, you must contact the Cisco TAC to open a service
request. The TAC engineer can place an order for the cable. Here are the part
For ONS 15327 and 15454, the part number is
For ONS 15600, the part number is
Complete these steps in order to recover the password:
Remove the standby TCC/TCC+/TCC2 card.
Note: The rest of this document refers to TCC/TCC+/TCC2 card as the TCC
Install one end of the password recovery cable to the TCC card you
just removed (see Figure 1).
You can locate these pins near the front/bottom of the right side
of the TCC card. The labels on the pins are RS232-DBG. The TCC card contains
two sets of RS232-DBG pins. Use the pins that are closer to the front of the
card (see the mouse pointer in Figure 1).
Note: Cisco recommends that you leave the pins slot on top unused on
the TCC side connection, so that you can re-insert the TCC card without
interference from the password recovery cable.
Figure 1 – Connection to TCC/TCC+/TCC2
Connect the DB9 portion of the cable to the serial
port of the PC through the serial port.
Run Hyper Terminal.
Specify these settings for the serial port (see Figure 2):

Bits per second: 9600
Data bits: 8
Stop bits: 1
Flow control: None
Reinstall the TCC.
Boot up the TCC.

Reset the active TCC.
Log into the ONS 15600, ONS 15454 or ONS 15327 node through Cisco
Transport Controller (CTC) in order to verify whether the reset to default
settings was successful. The default settings include CISCO15
as the username and a blank password.
Log into the ONS 15454 or ONS 15327 node through telnet after you
ensure that you can ping the node. Then, use the telnet <ip
address> command to access the NE. The username and password is the
same as in CTC. After you reset the password, CISCO15 is the
username and there is no password.
At the system prompt (->), type
bootChange, (see arrow A in Figure
6). Press ENTER until startup script appears. You
changed this parameter on the standby TCC that is now active. Therefore, you
need to remove this parameter now from the active TCC.

Log out of the telnet session.
If you use ONS 15454 version 3.4.2, you must make an additional
change in order to force a database write to the standby TCC card. In order to
do so, edit the site information or site contact in CTC. If you fail to perform
this step, the database reverts to the old password when you reset the active

Remove the TCC from the chassis.
Remove the password recovery cable.
Reinstall the TCC.
Note: Contact TAC if you have any questions about this procedure.
