Upgrading Cisco ONS 15327 Release 1.0.x or 3.3.x to 3.4

78-15236-01

Upgrade the Software

Note CTC will display the download status on the Maintenance > Software pane so you can monitor the file

transfer. The status changes to “complete” when the software has finished downloading. The software

download process can take 30 minutes or more, depending on the number of nodes in the network.

Activate the New Load

Log into and activate each node in the network, beginning with the node you performed the download

from.

Note Cisco recommends that the first node you activate be a LAN-connected node. This ensures that the new

CTC jar files will download to your workstation as quickly as possible.

Note Make sure all cards that are part of a protection group (1+1, 1:1, or 1:N) are active on the working card

of that protection group and that no protection switches are occurring. In other words, make sure that the

protect cards are in standby before proceeding.

Step 1 Perform a BLSR lockout appropriate for the software release from which you are upgrading. For

lockout procedures, refer to the user documentation for the specific software release.

Step 2 Log into the first node.

Step 3 Record the IP address of that node.

Step 4 Verify that the node has no active alarms. If alarms exist, clear them before proceeding.

Step 5 From the CTC node view, click the Maintenance > Software tabs.

Step 6 Verify that the protect version is 3.4.

Step 7 Click Activate. The Activate dialog box appears with a warning message. Click Yes.

Step 8 The “Activation Successful” message appears upon successful completion of the activation. Click OK

to begin the node rebooting process.

Step 9 After activating the node, wait until the software upgrade finishes at that node before continuing.

Each card installed in the node will activate and reboot, beginning with the standby XTC. Once the

standby XTC is fully activated and fully rebooted, the other XTC activates. Then the line cards reboot

consecutively from bottom to top (slot one to four). This process is service affecting for Ethernet traffic

only. Cisco recommends that you activate the new load during a maintenance window. Ethernet traffic

will be impacted for approximately one second during each XTC switch and again while each Ethernet

line card reboots. The Ethernet outage for any one of these cards could range from 45–60 seconds. After

all cards have rebooted, the standby XTC reboots again to ensure that all circuits are updated correctly.

The entire process takes up to 12 minutes. Once the standby XTC finishes its final reboot and all alarms

clear you can safely proceed to the next step.

Note The system can take up to 12 minutes to reboot.
