Before You Begin

Before beginning, write down the following information about your site; the data will be useful during and after the upgrade: Date, Street Address, Site Phone Number, and Dial Up Number.


Caution Read all procedures before you begin the upgrade.


Note Procedures in this document 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 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 15327, you might wish to check off each procedure on your printed copy of this document as you complete it.



Note Each non-trouble procedure (NTP) is a list of steps designed to accomplish a specific procedure. Follow the steps until the procedure is complete. If you need more detailed instructions, refer to the detail-level procedure (DLP) specified in the procedure steps. Throughout this guide, NTPs are referred to as "procedures" and DLPs are termed "tasks." Every reference to a procedure includes its NTP number, and every reference to a task includes its DLP number.



Note The DLP (task) supplies additional task details to support the NTP. The DLP lists numbered steps that lead you through completion of a task. Some steps require that equipment indications be checked for verification. When the proper response is not obtained, a trouble clearing reference is provided. This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).

Note During the lockout, BLSR spans will not be protected. You must leave the BLSR in the lockout state until you have finished activating all nodes in the ring, but then you must be sure to remove the lockout after you are finished activating.



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



Step 1 In node view, click the Maintenance > BLSR tabs.

Step 2 For each of the BLSR trunk (span) cards (OC-12, OC-48, or OC-192), perform the following steps:

a. Next to the trunk card row, click the East Switch column to show the drop-down menu.

b. From the menu options, choose Lockout Span.

c. Click Apply.

d. In the same row, click the West Switch column to show the drop-down menu.

e. From the menu options, choose Lockout Span.

f. Click Apply.


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



Note Certain BLSR alarms may be raised following activation of the first node in the ring. The following alarms, if raised, are normal, and should not cause concern. They will clear upon completion of the upgrade, once all nodes have been activated.

BLSR-OOSYNC (MN)

RING-MISMATCH (MJ)

APSCDFLTK (MN)

BLSR-RESYNC (NA)


Step 3 Return to your originating procedure (NTP).


DLP-U120 Activate the New Load

Purpose

This task activates Software R4.6 in each node in the network.

Tools/Equipment

PC or UNIX workstation

Prerequisite Procedures

U118 Download Release 4.6 Software

U119 Perform a BLSR Lockout (if required)

Required/As Needed

Required

Onsite/Remote

Onsite or remote (but in the presence of the workstation)

Security Level

Superuser



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 Ensure 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, ensure that the protect cards are in standby before proceeding. Move your mouse cursor over a card in node view to see its active or standby status.



Step 1 Record the IP address of the node. The IP address is on the upper left corner of the CTC window.

Step 2 Verify that the alarm filter is not on:

a. Click the Alarms tab.

b. Click the Filter tool at the lower-right side of the bottom toolbar.

Alarm filtering is enabled if the tool is depressed (selected) and disabled if the tool is raised (not selected).

Step 3 On the Alarms tab, check all nodes for existing alarms. Resolve any outstanding alarms before proceeding.

Step 4 Click the Maintenance > Software tabs.

Step 5 Verify that the protect version is 4.6.

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. Click OK in the message box.


Note When you click Yes, CTC will lose connection to the node and will display the network view.


Step 8 After activating the node, wait until the software upgrade reboot finishes at that node before continuing. The following occurs:

Each card in the node resets, beginning with the standby XTC card. When the standby XTC comes back up, it remains standby. Then the active XTC resets and comes back as active. When the XTCs are finished, the Ethernet cards reset, followed by the line cards. Once the line cards have finished, the standby XTC resets a final time. The whole process can take up to 12 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 a hit of up to 50 ms. Expect Ethernet traffic to remain down from the time the active XTC resets, until all Ethernet cards have finished resetting and come back up (this will take 2 to 4 minutes).

After all the cards finish resetting and all alarms clear, you can safely proceed to the next step. (If you are upgrading remotely and cannot see the nodes, wait for 15 minutes for the process to complete, then check to ensure that all alarms have cleared before proceeding.)


Caution The upgrade process is service affecting, so Cisco recommends that you activate the new load during a maintenance window. Time-division multiplexing (TDM) traffic can endure a hit of up to 50 ms. Ethernet traffic may remain down from the time the XTC cards switch to the time all Ethernet cards have finished resetting.

Step 9 In CTC, choose File > Exit.

Step 10 In your browser window, click "Delete CTC Cache."


Note You must ensure that CTC is closed before clicking the "Delete CTC Cache" button. CTC behavior will be unreliable if the button is clicked while the software is still running.



Note It might also be necessary to delete cached files from your browser's directory, or from the "temp" directory on your MS Windows workstation. If you have trouble reconnecting to CTC, complete the "DLP-U121 Delete Cached JAR Files" task.


Step 11 Reconnect to CTC using the IP address from Step 1. The new CTC applet for Software R4.6 uploads. During this logon, type the user name CISCO15. A password is not required.


Note Steps 9 through 11 are only necessary after upgrading the first node in a network because cached files only need to be removed from your workstation once. For the remaining nodes, you will still be disconnected and removed to the network view during the node reboot, but after the reboot is complete, CTC will restore connectivity to the node.


Step 12 Return to your originating procedure (NTP).


DLP-U121 Delete Cached JAR Files

Purpose

This task manually deletes cached JAR files from your browser and hard drive. 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.

Grant always—Installs the public-key certificate and does not delete it after the session is over. Cisco recommends this option.

View Certificate—Allows you to view the public-key security certificate.

Step 3 If the Login dialog box appears, you have completed this procedure. If the Change Java Policy File dialog box appears, complete this step. The Change Java Policy File dialog box appears if CTC finds a modified Java policy file .java.policy on your computer. In Software R4.0 and earlier, the Java policy file was modified to allow CTC software files to be downloaded to your computer. Choose one of the following options:

Yes—Removes CTC-related entries from the modified Java policy file from your computer. Choose this option only if you will log into ONS 15327 nodes running Software R4.1 or later.

No—Does not remove CTC-related entries from the modified Java policy file from your computer. Choose this option if you will log into ONS 15327 nodes running Software R4.0 or earlier. If you choose No, this dialog box will appear every time you log into the node. If you do not want it to appear, check the Do not show the message again check box.


Caution If you delete CTC-related files from the Java policy file, you cannot log into nodes running Software R4.0 and earlier. If you want to log into an ONS 15327 node running an earlier release, insert the software CD for the release into your PC CD-ROM and run the CTC setup wizard to reinstall the Java policy file. In the CTC setup wizard, choose the custom installation option.

After you complete the security certificate dialog boxes, the web browser displays information about your Java and system environments. If this is the first login, CTC downloading message appears while CTC files are downloaded to your computer. The first time you connect to an ONS 15327 node, this process can take several minutes. After the download, the CTC Login dialog box appears.

Step 4 If you need to return to the software and database you had before activating Software R4.6, proceed with the "U71 Revert to Previous Software Load and Database" procedure.

Stop. You have completed this procedure.

Note To perform a supported (non service affecting) revert from Software R4.6, the release you want to revert to must have been working at the time you activated to Software R4.6 on that node. Also, a supported revert automatically 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 1 From the node view, click the Maintenance > Software tabs.

Step 2 Verify that the protect software displays 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.

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

Step 5 Wait until the software revert finishes before continuing.


Note The system reboot might take up to 12 minutes to complete.


Step 6 Close your Netscape or Internet Explorer browser.

Step 7 Wait one minute before reverting another node.


Note After you upgrade to JRE 1.4.2, you cannot log into an ONS 15454, ONS 15454 SDH, or ONS 15327 node until you reconfigure the Java Plug-in to use JRE 1.3.1. If you are reverting to a release that uses JRE 1.3.1_02, and you retained JRE 1.3.1_02 during the upgrade, you do not need to do anything.


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 to your workstation.


Note It might also be necessary to delete cached files from your browser's directory or from the TEMP directory on your MS Windows workstation. If you have trouble reconnecting to CTC, see the "DLP-U121 Delete Cached JAR Files" task.


Step 9 Return to your originating procedure (NTP).

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


Caution This process is service affecting and should be performed during a maintenance window.


Step 1 In the CTC node view, click the Maintenance > Database tabs.

Step 2 Click Restore. The Open dialog box appears.

Step 3 Select the previously saved file and choose Open.

The database will be restored and the XTC cards will reboot.

Step 4 When the XTC cards have rebooted, log back into CTC and verify that the database is restored.

Wait one minute before restoring the next node.

Step 5 You have now completed the manual database backup.

Step 6 Return to your originating procedure (NTP).

Opening a TAC Case

Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:

http://www.cisco.com/tac/caseopen

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

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

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—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.

Priority 2 (P2)—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.

Priority 3 (P3)—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.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
