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

78-15236-01

Upgrade the Software

After backing up the database and logging all of the required information, insert the Release 3.4 software

CD into the workstation (or otherwise acquire access to the software) and begin the upgrade process.

You must download and activate the software.

Caution A traffic interruption of less than 60 ms on each circuit is possible during the activation, with Ethernet

traffic impacted for approximately one second during each XTC switch and also when each Ethernet line

card reboots (45–60 seconds per card).

Caution Do not perform maintenance or provisioning activities during the activation phase.

There are two flash RAMs on the XTC card. An upgrade downloads the software to the backup RAM on

both the backup and active XTCs. This procedure does not affect traffic because the active software

continues to run at the primary RAM location; therefore, you can download the software at any time.

Download

Step 1 Check all nodes in the ring for existing alarms. Resolve any outstanding alarms before proceeding.

Note During the software download process, an alarm, SFTWDWN, indicates that the software download is

taking place. This is normal and clears when the download is complete.

Step 2 Using CTC Release 2.3, or Release 3.3, log into the node from which you will download the software.

Note Starting with the node most directly connected to your workstation will achieve the best download

performance; however, in some networks it may be safer to begin your upgrade at the farthest node and

proceed toward the one you are most directly connected to. This ensures that no node will be at risk of

being stranded if unforeseen circumstances cause the upgrade to fail. This issue is a matter of network

administration policy.

Step 3 From the CTC network view, click the Maintenance > Software tabs.

Step 4 Click Download. The Software Download dialog box opens.

Step 5 Click Browse to locate the software files. The File Open dialog box opens.

Step 6 Open the ONS 15327 folder.

Step 7 Select the file with the “.pkg” extension and click Open. The Software Download dialog box opens.

Step 8 In the list of compatible nodes, select the checkboxes for all nodes you are downloading the software

to.

Step 9 Enter the number of nodes you have selected in the “Concurrent Downloads” field.

Step 10 Click OK.
