Step−by−step Procedure to Recover the Password

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 numbers:

For ONS 15327 and 15454, the part number is 15454−15454−EPC=.♦

For ONS 15600, the part number is 15600−TPC=.♦

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 card.

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.3.

Run Hyper Terminal.4.

Specify these settings for the serial port (see Figure 2):

Bits per second: 9600♦

Data bits: 8♦

Parity: None♦

Stop bits: 1♦

Flow control: None♦
