Upgrading Cisco ONS 15454 SDH Release 3.3 to Release 3.4 Using the TCC-I Card


This document explains how to upgrade the Cisco ONS 15454 SDH Cisco Transport Controller (CTC) software from Software R3.3 to Software R3.4 using the Timing, Communications, and Control-International (TCC-I) card.

Before You Begin

Before beginning, write down the following information about your site: date, street address, site phone number, and dial-up number. The data will be useful during and after the upgrade.


Caution Read each procedure before you begin the upgrade.

Note Procedures in this chapter are to be performed in consecutive order unless otherwise noted. In general, you are not done with a procedure until you have completed it for each node that you are upgrading, and you are not done with the upgrade until you have completed each procedure that applies to your network. If you are new to upgrading the ONS 15454 SDH, you might wish to check off each procedure on your printed copy of this chapter as you complete it.


Each section begins with an overview procedure, followed by a detailed procedure for each step.

Section Prepare for Release 3.3 to Release 3.4 Upgrade—Review this critical information and complete these critical procedures before beginning the upgrade process.

Section Back Up the Database—Complete the database backup to ensure that you have preserved your node and network provisioning in the event that you need to restore them.

Section Upgrade the Software—Complete these procedures to upgrade the software. You must complete the entire procedure before the upgrade is finished.

Section Revert to Previous Load—Complete this procedure only if you need to return to the software load you were running before activating the Release 3.4 software.

Onsite or remote (but in the presence of a PC or UNIX workstation)



Note There are two flash RAMs on the TCC-I card. An upgrade downloads the software to the backup RAM on both the backup and active TCC-I cards. The download 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.



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


Note During the software download process, the SWFTDWN alarm indicates that the software download is taking place. The alarm is normal and clears when the download is complete.


Step 2 From the CTC network view, click the Maintenance > Software tabs.

Step 3 Click Download. The Download Selection dialog box appears.

Step 4 Browse to locate the software files on the ONS 15454 SDH System Software CD (or on your hard drive, if you are working from a local copy).

Step 5 Open the Cisco15454SDH folder.

Step 6 Select the file with the .pkg extension and click Open.

Step 7 In the list of compatible nodes, select the check boxes for all nodes you are downloading the software to.


Note Cisco advises that you limit concurrent software downloads to 3 nodes at once.


Step 8 Click OK. The Download Status column monitors the progress of the download.


Note The software download process can take 30 minutes or more per node.


Step 9 After you have successfully downloaded the CTC Release 3.4 software to each node you are upgrading, perform the "Perform an MS-SPRing Lockout" procedure. If none of your nodes participate in an MS-SPRing, you can skip the MS-SPRing lockout and begin the "Activate the New Load" procedure.


Perform an MS-SPRing Lockout

Purpose

If any of the nodes you are upgrading are in an MS-SPRing configuration, you must perform a span lockout at each node in the ring before activating the software for Release 3.4. Perform this procedure to issue a span lockout on an MS-SPRing using CTC Release 3.3.

Tools/Equipment

PC or UNIX workstation

Prerequisite Procedures

"Download the Release 3.4 Software" procedure

Required/As Needed

Required for MS-SPRing

Onsite/Remote

Onsite or remote (but in the presence of a PC or UNIX workstation)



Note During the lockout, MS-SPRing spans are not protected. Be sure to remove the lockout after activating all nodes in the ring.



Note To prevent ring or span switching, perform the lockout on both the east and west spans of each node.



Step 1 Click the Maintenance > Ring tabs.

Step 2 For each of the MS-SPRing trunk cards (STM-4, STM-16, STM-64), go to the row in the table for that card and perform the following steps:

a. Click the East Switch column to show the pull-down menu.

b. From the menu options, choose Span Lockout.

c. Click the West Switch column to show the pull-down menu.

d. From the menu options, choose Span Lockout.

e. Click Apply to activate the command.

Step 3 Repeat Step 2 at each node in the ring.


Note Ignore any Default K alarm or alarms that occur on the protect STS timeslots during this lockout period.



Note Leave the MS-SPRing in the lockout state until you have finished activating all nodes.


Step 4 You have completed the MS-SPRing lockout. You must now perform the "Activate the New Load" procedure.


Activate the New Load

Purpose

Use this procedure to log into and activate each node in the network.

Tools/Equipment

PC or UNIX workstation

Prerequisite Procedures

Perform the "Download the Release 3.4 Software" procedure. "Perform an MS-SPRing Lockout" procedure first if any of the nodes you are upgrading are in an MS-SPRing configuration.

Required/As Needed

Required

Onsite/Remote

Onsite or remote (but in the presence of a PC or UNIX workstation)



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 PC or workstation as quickly as possible.



Note Make sure that 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 mode before proceeding.



Step 1 Log into a node.

Step 2 Record the IP address of that node.

Step 3 Verify that the node has no new alarms. If alarms exist, clear them before proceeding.

Step 4 From the CTC node view, click the Maintenance > Software tabs.

Step 5 Verify that the protect version is 3.4.

Step 6 Click Activate. The Activate dialog box appears with a warning message.

Step 7 Click Yes to proceed with the activation. The Activation Successful message appears when the software is successfully activated.

Step 8 Click OK to begin the node rebooting process.

Step 9 After activating the node, wait until the software upgrade reboot finishes at that node before continuing. A system reboot (SYSBOOT) alarm is raised while activation is in progress. After all cards have reset, this alarm clears.

Each card in the node reboots, beginning with the standby TCC-I. After the standby TCC-I is fully activated and fully rebooted, it becomes the active TCC-I and the other TCC-I reboots. When the TCC-I cards are finished, the XC10G in Slot 8 reboots, and then the XC10G in Slot 10 reboots. Next, the Ethernet cards reset all at once, then the line cards boot consecutively from left to right. The whole process can take up to 30 minutes, depending on how many cards are installed. This process is service affecting, so Cisco recommends that you activate the new load during a maintenance window. Time-division multiplexing (TDM) traffic can endure an outage of up to 50 ms. Expect Ethernet traffic to remain down from the time the TCC-I cards switch to the time all Ethernet cards have finished resetting. After all the cards finish rebooting and all alarms clear, you can safely proceed to the next step. (If you are upgrading remotely and cannot see the nodes, wait 30 minutes for the process to complete, then check to ensure that all alarms have cleared before proceeding.)


Note Steps 10 to 12 are only necessary after upgrading the first node. For the remaining nodes, you will still be disconnected and moved to the network view during the node reboot, but after the reboot is complete, CTC will restore connectivity to the node.


Step 10 In CTC, choose File > Exit.

Step 11 Follow all steps in the "Delete Cached JAR Files" procedure, then continue here with Step 12.

Step 12 Reconnect to CTC using the IP address from Step 2. (If the IP address is still in the browser location bar, you can simply hold down the Shift key and click the browser Reload or Refresh button.) The new CTC applet for Release 3.4 uploads. Because CTC Release 3.4 is backwardly compatible with CTC Release 3.3, the network view is visible while you are upgrading.


Note Only activate one node at a time.


Step 13 Perform Steps 1 to 9 for each of the remaining nodes. The activation must be performed for every node that is running CTC Software R3.3. Allow each node to finish (all alarms cleared for 10 minutes) before activating the next node.

Step 14 You have completed the activation procedure when you have activated all nodes with CTC Software R3.4. If you performed an MS-SPRing lockout before you began activation, you must now perform the "Remove the MS-SPRing Lockout" procedure, then go to the "Set the Date and Time" procedure.


Delete Cached JAR Files

Purpose

When you upgrade or revert to a different CTC software load, you must reload CTC to your browser. Before you can reload CTC you must ensure that previously cached files are cleared from your browser and hard drive.

Step 3 Delete cached files from your PC (Windows systems only).

a. In your Windows start menu, choose Settings > Control Panel > System > Advanced.

b. Click Environment Variables. This shows you a list of user variables and a list of system variables.

c. In the list of user variables, look for the variable "TEMP." The value associated with this variable is the path to your temporary directory where jar files are stored.

d. Open the temporary directory located in the path you just looked up.

e. Choose View > Details.

f. Select and delete all files with "jar" in either the name or type field.

Step 4 Reopen your browser. You should now be able to connect to CTC.

Step 5 After deleting cached jar files, you should return to the referring procedure (either the "Activate the New Load" procedure, or the "Revert to Protect Load" procedure) and continue with the steps there.


Remove the MS-SPRing Lockout

Purpose

Release the span lockouts on all MS-SPRing nodes after the new software load is activated on all nodes. This procedure restores an MS-SPRing using Software R3.4.

b. From the menu options, choose Clear.

c. Click Apply to activate the command.


Note When removing a lockout, be sure to apply your changes after each time you choose the Clear option. If you try to select Clear for more than one lockout at a time, you risk traffic loss on the first ring switch.


d. In the same row, click the East Switch column to show the pull-down menu.

e. From the menu options, choose Clear.

f. Click Apply to activate the command.

Step 3 You might need to accept a new ring map to clear Default K byte or Node ID mismatch alarms.

a. From the Provisioning > MS-SPRing tabs, click the Ring Map button.

b. If a new ring map exists, click Accept.

Step 4 When all MS-SPRing span lockouts are released, you have completed this procedure. Go to the "Set the Date and Time" procedure.


Set the Date and Time

Purpose

If you are not using SNTP, the upgrade procedure can cause the Date/Time setting to change. Perform this procedure to reset the date and time at each node.

Tools/Equipment

PC or UNIX workstation

Prerequisite Procedures

If required, perform the "Remove the MS-SPRing Lockout" procedure; then "Delete Cached JAR Files" procedure and "Activate the New Load" procedure

Required/As Needed

As needed

Onsite or remote (but in the presence of a PC or UNIX workstation)



Note If you are using SNTP, you do not need this procedure and can go to the "Upgrade Spare TCC-I Cards" procedure.



Step 1 In CTC node view, click the Provisioning > General tabs.

Step 2 Set the correct date and time, then click Apply.

Step 3 Repeat Steps 1 and 2 for each remaining node.

Step 4 When all nodes have the correct date and time settings, go to the "Upgrade Spare TCC-I Cards" procedure.


Upgrade Spare TCC-I Cards

Purpose

Perform this procedure to upgrade all spare TCC-I cards to CTC Software R3.4. The provisioning database will also be copied to the spare TCC-I cards.

Tools/Equipment

PC or UNIX workstation

Prerequisite Procedures

"Remove the MS-SPRing Lockout" procedure if required; otherwise, "Activate the New Load" procedure and "Delete Cached JAR Files" procedure

Required/As Needed

Required for all spare TCC-I cards

Onsite/Remote

Onsite or remote (but in the presence of a PC or UNIX workstation)



Step 1 To upgrade a spare TCC-I, place it in the standby slot of a node running Software R3.4. The card upgrades automatically from the active TCC-I.

The standby TCC-I copies one or both software releases from the active TCC-I, as needed. Each software copy takes about 15 minutes, and the TCC-I resets after each copy. Thus, for a TCC-I that has no matching software with the active TCC-I, you should expect to see two TCC-I resets, lasting about 30 minutes total.


Note During the TCC-I upgrade, the LEDs on the upgrading card flash alternately between Fail and Standby.


Step 2 After you have upgraded all of your spare TCC-I cards, you have completed the software upgrade.


1.2  Revert to Previous Load

Purpose

Use this procedure to return to the exact software and database provisioning you had before you activated Software R3.4.

Tools/Equipment

PC or UNIX workstation

Prerequisite Procedures

"Prepare for Release 3.3 to Release 3.4 Upgrade" section, "Back Up the Database" section, and "Upgrade the Software" section (up to and including the "Activate the New Load" procedure, and the "Remove the MS-SPRing Lockout" procedure, if applicable)

Required/As Needed

As needed

Onsite/Remote

Onsite or remote (but in the presence of a PC or UNIX workstation)



Note The procedures to revert to a previous load are not a part of the upgrade. They are provided here as a convenience to those wishing to perform a revert after an upgrade. If you have performed all necessary procedures up to this point, you have finished the software upgrade.



Note Before you upgraded from Software R3.3 to Software R3.4, you should have backed up the existing database at all nodes in the network. (This is part of the "1.2  Back Up the Database" procedure.) Cisco recommends that you record or export all critical information to your hard drive. If you need to revert to the backup database, use the following procedures, in order.



Step 1 Complete the "Perform an MS-SPRing Lockout" procedure (MS-SPRing only).

Step 2 Complete the "Revert to Protect Load" procedure.

Step 3 Complete the "Remove the MS-SPRing Lockout" procedure (MS-SPRing only).


Note The "Manually Restore the Database" procedure is provided for reference only. Do not complete this procedure unless an attempt to revert has failed.


Step 4 After you have completed the necessary steps above, the revert is complete.


Perform an MS-SPRing Lockout

Purpose

If you have an MS-SPRing provisioned, before beginning the revert you must perform a span lockout at each node. Perform this procedure to issue a span lockout on an MS-SPRing using CTC Software R3.4.

Tools/Equipment

PC or UNIX workstation

Prerequisite Procedures

"Prepare for Release 3.3 to Release 3.4 Upgrade" section; "Back Up the Database" section; "Upgrade the Software" section (up to and including the "Activate the New Load" procedure, and the "Perform an MS-SPRing Lockout" procedure)

Required/As Needed

Required for MS-SPRing only

Onsite/Remote

Onsite or remote (but in the presence of a PC or UNIX workstation)



Step 1 If you have an MS-SPRing provisioned, before beginning the revert you must perform a span lockout at each node. Follow the "Perform an MS-SPRing Lockout" procedure to perform a span lockout on an MS-SPRing using CTC Software R3.4.


Note Leave the MS-SPRing in the lockout state until you have finished reverting all nodes.


Step 2 After you have performed the MS-SPRing lockout on all MS-SPRing nodes, perform the "Revert to Protect Load" procedure.


Revert to Protect Load

Purpose

Revert to the software you were running prior to the last activation. This procedure also restores your database to the provisioning you had prior to the activation.

Tools/Equipment

PC or UNIX workstation

Prerequisite Procedures

"Prepare for Release 3.3 to Release 3.4 Upgrade" section; "Back Up the Database" section; "Upgrade the Software" section (up to and including the "Activate the New Load" procedure, and the "Remove the MS-SPRing Lockout" procedure, if applicable); "Perform an MS-SPRing Lockout" procedure (if required)

Required/As Needed

Required for revert

Onsite/Remote

Onsite or remote (but in the presence of a PC or UNIX workstation)



Note To perform a supported (non-service-affecting) revert from Software R3.4, the release you wish to revert to must have been working at the time you activated CTC Software R3.4 on that node. A supported revert automatically restores the node configuration to its state at the time of the previous activation. Thus, any configuration changes made after activation will be lost when you revert the software.



Step 1 From the node view, click the Maintenance > Software tabs.

Step 2 Verify that the protect software displays 3.3 (the release you upgraded from).

Step 3 Click Revert. Revert activates the protect software and restores the database from the previous load. A dialog box asks you to confirm the choice.


Caution A traffic interruption of less than 60 ms on each circuit is possible during the activation procedure, with Ethernet traffic disruption possibly lasting up to several minutes on each circuit.

Step 4 Click OK. This begins the revert and drops the connection to the node.

Step 5 After reverting the node, wait until the software revert finishes at that node before continuing.


Note Be patient. The system reboot might take up to 30 minutes to complete.


Step 6 Close your Netscape or Internet Explorer browser.

Step 7 Wait one minute before restoring another node.

Step 8 After reverting all of the nodes in the network, restart the browser and log back into the last node that was reverted. This uploads the appropriate CTC applet for Software R3.3 to your PC or workstation.


Note It might also be necessary to delete cache files from your browser's directory, or from the "temp" directory on your MS Windows PC. If you have trouble reconnecting to CTC, complete the "Delete Cached JAR Files" procedure.


Step 9 Remove any MS-SPRing lockout using the "Remove the MS-SPRing Lockout" procedure.


Remove the MS-SPRing Lockout

Purpose

To restore MS-SPRing protection, you must clear the span lockouts on all MS-SPRing nodes after reverting the software load and restoring the database on all nodes. Use the following procedure to restore an MS-SPRing using Software R3.x.

Tools/Equipment

PC or UNIX workstation

Prerequisite Procedures

"Perform an MS-SPRing Lockout" procedure, and "Revert to Protect Load" procedure

Required/As Needed

Step 1 To restore MS-SPRing protection, you must clear the span lockouts on all MS-SPRing nodes after reverting the software load and restoring the database on all nodes. Complete the "Remove the MS-SPRing Lockout" procedure to restore an MS-SPRing using Software R3.x.

Step 2 You have now completed the software revert procedure. All nodes should be provisioned as they were before the last activation; however, in case of trouble, Cisco provides the "Manually Restore the Database" procedure to retrieve your databases.


Manually Restore the Database

Purpose

The revert procedure should have restored your Software R3.x database completely; however, as a precaution, Cisco includes here the steps to restore the pre-upgrade database manually.


Caution Do not perform these steps unless the software revert failed.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool automatically provides recommended solutions. If your issue is not resolved using the recommended resources, your service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553 2447

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
