Note Before you upgraded to Release 6.2 software, you should have backed up the existing database at all nodes in the network (using the "NTP-U142 Back Up the Software Database" procedure). Cisco recommends that you record or export all critical information to your hard drive.



Caution Downgrades are service affecting.


Note A system-wide soft reset occurs after the database is restored. All line (I/O) and matrix (SSXC) cards automatically soft reset. Existing traffic can be affected, depending on the circuit provisioning map.



Step 1 Log into the node. For detailed instructions, refer to the Cisco ONS 15600 Procedure Guide. If you are already logged in, continue with Step 2.


Note To perform a downgrade from Software R6.2, Software R5.x must have been working at the time you activated to Software R6.2 on that node. Also, a supported revert restores the node configuration at the time of the previous activation. Thus, any configuration changes made after activation will be lost when you revert the software.


Step 2 (BLSR nodes only) Complete the "DLP-U218 Perform a BLSR Lockout" task.


Note The BLSR lockout must be completed for all nodes in all rings for which the ONS 15600 is provisioned.


Step 3 Complete the "DLP-U219 Download the Software" task.

Step 4 Click Revert. The Database Restore dialog box appears.

Step 5 Click Browse.

Step 6 In the Open dialog box, navigate to a local PC directory or network directory where the database file is stored and click Open.

Step 7 If alarms and performance were backed up, check the Alarms and Performance check boxes in the Database Restore dialog box.

Step 8 Click OK.

Step 9 Click Yes in the confirmation dialog box.

Step 10 Wait until the software download finishes. The Download Status column shows:

The Qualifying percentage completed (approximately 1 to 2 minutes)

The status "Wait" while the standby TSC reboots (approximately 2 to 5 minutes)

The Acquiring percentage completed as the standby TSC acquires the active timing reference (approximately 10 to 15 minutes)

The ONS 15600 then reboots.

Step 11 Complete the "DLP-U222 Remove the BLSR Lockout" task for all BLSR nodes in the network.

Step 12 Complete the "DLP-U221 Accept the New Load" task.

Step 13 Repeat Steps 1 through 12 for any other nodes you want to downgrade.

Stop. You have completed this procedure.
