Upgrading Cisco ONS 15454 Release 2.2.x to 2.2.2 Using the TCC+ Card
This document explains how to upgrade Cisco ONS 15454's Cisco Transport Controller (CTC) software from Release 2.2.x to Release 2.2.2 using the Timing, Communications, and Control + (TCC+) card.
Before beginning, write down the following information about your site; the data will be useful during and after the upgrade: Date, Node Name, Node Location, Street Address, Site Phone Number, Node IP Address, Subnet Mask, Dial Up Number, and Node ID.
Caution Read each procedure before you begin the upgrade.
This section contains critical information that you must read before the upgrade process.
Read the Release Notes for Cisco ONS 15454 Release 2.2.2 before you begin this upgrade procedure.
Caution Use this document with the TCC+ card only. To upgrade using the TCC card, see Upgrading Cisco ONS 15454 Release 2.2.x to 2.2.2 Using the TCC Card.
Note Upgrading to a new CTC release can create limitations to your ability to use the Cisco Transport Manager (CTM). If you are using CTM, before you choose to upgrade to a new CTC release you should check the latest CTM Release Notes for any possible compatibility issues. The CTM Release Notes can be found at:
CTC Workstation Requirements
Before upgrading the workstation to run CTC Release 2.2.2, verify all hardware and software requirements.
•A Windows or Unix workstation:
–IBM-compatible PC with a 486 or higher processor, CD ROM drive, and 128 MB RAM running Windows 95, Windows 98, Windows 2000, or Windows NT
–UNIX workstation running Solaris
•Direct connection to the ONS 15454 using 10baseT Ethernet Network Interface Card (NIC) and Ethernet Cable (use the CAT 5 10baseT Patch cable to connect to the TCC+)
•Browser software (select one):
–Netscape Navigator 4.08 or higher (Netscape Navigator is included on the ONS 15454 software CD shipped with the node.)
–Netscape Communicator 4.61 or higher
–Internet Explorer 4.0 Service Pack 2 or higher
•Java Policy File and Java Runtime Environment file (included on the ONS 15454 software CD)
DNS & WINS Setting
When setting up TCP/IP Network properties for a workstation that will run CTC Release 2.0, ensure that DNS and WINS resolution are disabled. WINS resolution is rarely used, but DNS is commonly used in corporate networks. When DNS is enabled it causes CTC to hang and requires a TCC+ side switch at every network node to correct the lockup.
IP Address Caveat
Disable all other Ethernet devices (such as a dial-up adapter) on the workstation that runs CTC.
If you have multiple IP addresses on your workstation, you must remove them; you cannot install CTC Release 2.2.2 if multiple IP addresses are running.
If you have multiple ONS 15454 nodes configured in the same IP subnet, only one can be connected to a router. Otherwise, the remaining nodes might be unreachable. Refer to the Cisco ONS 15454 User Documentation, Release 2.2.1 for LAN-connection suggestions.
Valid Craft Port
The front-panel Ethernet interface is changed in Release 2.0.
The permanent wire-wrap LAN connection on the backplane will communicate with the node if either TCC (A or B) is active or if the front-panel TCC connection is used.
When using Release 2.2.0 or greater you can connect through either of the TCC+ RJ-45 ports regardless of which one is active.
You must now use CTC to check for duplex common modules.
Step 1 Log into the node.
Step 2 Ensure that slots 7, 8, 10, and 11 have cards installed. Release 2.2.x does not support simplex operation.
Step 3 Repeat Steps 1 and 2 at every node in the network.
Make sure all active telnet sessions to any node in the network are closed.
A new superuser, CISCO15, was added to Release 2.2.0.
You can currently use the cerent454 superuser name, but this username will be phased out in a future release.
Verify that all AIP boards on each node are revision 003A, A0 or B0. All AIP boards with revision 005x must be swapped. Repeat for every node.
Back Up the Database
Before upgrading from Release 2.2.x to Release 2.2.2 software, you must back up the current database for all nodes in the network.
Step 1 Log into CTC.
Step 2 From the node view, click the Maintenance > Database tabs.
Step 3 Click Backup.
Step 4 Save the database on the workstation's hard drive or on network storage. Use an appropriate file name with the file extension .db (for example, myDatabase.db).
Step 5 Click Save. The File Received dialog box appears.
Step 6 Click OK.
Cisco recommends that you manually log critical information by either writing it down or printing screens where applicable. This step is optional after you have backed up the database. Use the following table to determine the information you should log; complete the table (or your own version) for every node in the network.
Upgrade the Software
After backing up the database and logging all of the required information, insert the Release 2.2.2 software CD into the workstation and begin the upgrade process. You must upload and activate the software.
Caution Temporary traffic interruption is possible during the activation.
Caution Do not perform maintenance or provisioning activities during the upgrade process.
If you are upgrading from Release 2.2.0, you must now run the ptfix.exe script (PC) or pftix.pl script (UNIX). If you are upgrading from Release 2.2.1, go to the "Upload" section.
The TCC+ card has two flash RAMs. An upgrade uploads the software to the backup RAM on both the backup and active TCC+ cards. This procedure does not affect traffic because the active software continues to run at the primary RAM location; therefore, you can upload the software at any time.
Run the Script
This procedure is only necessary with Release 2.2.0 upgrades for TCC+. If you are upgrading from Release 2.2.1, you can skip this procedure and continue with the "Upload" section.
Caution Do not run the script on more than one node and one workstation at the same time.
Running the script takes approximately 2 to 3 minutes.
Step 1 Using CTC Release 2.2.0, log into the farthest node from the node connected to the workstation.
Step 2 Check the ONS 15454 for existing alarms. Resolve any outstanding alarms before proceeding.
Step 3 From the node view, click the Maintenance > Software tabs.
Step 4 Verify that the active load is 2.2.0 (02.20-001A-00.38).
Note The script will only work for the Release 2.2.0 (02.20-001A-00.38) load.
Step 5 Close all active telnet connections to the ONS 15454.
Step 6 Run the script:
In a command window, from the CD software "Cisco15454" directory, run ptfix.exe using the IP address of the node you are running the script on.EXAMPLE G:\Cisco15454> ptfix 172.16.17.18
This step takes approximately 2 to 3 minutes. When the script has completed successfully, an "Upgrade Preparation Complete" message appears.
Step 7 Close CTC and then reconnect to the same node you were previously connected to (farthest from the node you ran the script on).
Step 8 From the network view, log into the node you ran the script on.
Step 9 Click the Maintenance > Software tabs.
Step 10 Verify that the protect software is now "none."
Note Rerun the script if at any time the active/standby TCC+ reboots before the Release 2.2.2 load is activated.
Step 1 Check all nodes in the ring for existing alarms. Resolve any outstanding alarms or abnormal conditions before proceeding.
Step 2 Ensure that no outstanding alarms are being declared against any synchronization facility. Clear any minor, major, or critical alarms on synchronization facilities before proceeding.
Note Information alarms are blue in color; you can disregard these.
Step 3 After checking and resolving alarms on all nodes, upload the software only to the node you started with. For Release 2.2.0 upgrades, this will be the node for which you most recently ran the script.
Note During the software upgrade process, an alarm indicates that the software upgrade is taking place. This is normal and clears when the upgrade is complete.
Step 4 Return to the node you are upgrading and, from the node view, click the Maintenance > Software tabs.
Step 5 Click Upgrade. The Software Upgrade dialog box opens.
Step 6 Browse to the CD-ROM drive directory and open the "Cisco15454" folder.
Step 7 Select the file with the ".pkg" extension and click Open. CTC displays a status window so you can monitor the upgrade process. A message indicating that your files transferred successfully will appear after the software has finished loading.
Caution Do not close CTC during the upgrade. Closing CTC will abort the upgrade process.
Note The upgrade process can take 30 minutes or more.
Before You Activate
BLSR Nodes Only
If the node is in a bidirectional line switched ring (BLSR) configuration, you must complete the following steps before activating the new load.
Step 1 Perform a ring lockout to prevent switches from occurring during the upgrade.
a. Click the Maintenance > Ring tabs.
b. Right-click on one of the trunk cards (OC12 or OC48) and choose Ring Lockout from the pull-down menu.
c. Click Apply to activate the command. Leave the node in this state until the software is activated.
Note A Default K alarm or alarms on the protect STS timeslots can occur during this lockout period. Ignore these alarms if they occur.
Step 2 Repeat Step 1 at every node in the BLSR.
Step 3 Using CTC, reset each BLSR trunk card (OC12/OC48) one at a time.
Note If a card does not reset, do not continue with the activation process. Physically reseat the card if necessary. If you need to reseat the card or cards, make sure you first release all lockouts on protection switches. Once the card is rebooted and active, issue the lockouts again.
Step 4 Repeat Step 3 at every node in the BLSR.
Perform the following steps for all nodes in the network.
Step 1 Make sure all cards that are part of a protection group (1:1 and 1:N) are active on the working card of that protection group and that no protection switches are occurring. In other words, make sure protect cards are in standby before proceeding.
Step 2 To ensure database synchronization, run the memAudit utility:
a. Close all active telnet connections to the ONS 15454.
b. Copy the memAudit.exe from the ONS 15454 software CD or the following Cisco.com web page to a folder on your hard drive:
c. In a command window, change the prompt to the folder where the memAudit.exe is located.
d. At the prompt, type the following command:
memAudit <nodename or IP address>
Note Optional parameters exist for the memAudit command. For more information about the memAudit utility, view the memAudit_readme.htm file on the CD or Cisco.com web page.
Activate the New Load
Log in and activate each node beginning with the farthest node in the network and ending with your workstation node.
Step 1 Log into the node you ran the script on.
Step 2 Verify that the node has no active alarms.
Step 3 From the node view, click the Maintenance > Software tabs.
Step 4 Verify that the protect software displays 2.2.2.
Step 5 Click Activate. The Activate dialog box appears with a warning message.
Step 6 Click Yes to proceed with the activation. The first portion of the activation completes in 2 to 3 minutes, followed by a message confirming that activation is complete and the node will now reboot.
Step 7 Click OK.
Step 8 Wait until the software upgrade finishes at that node before continuing.
Activation proceeds from the node through each card installed, beginning with the standby TCC+. Once the standby TCC+ is fully activated and fully rebooted, it becomes the active TCC+ and the other TCC+ reboots. Then the XC or XCVT and AIC reboot; next, the line cards boot from left to right one by one. The whole process takes approximately 30 minutes. This process is traffic affecting, so Cisco recommends that you activate the new load during a maintenance window. TDM traffic will endure a 50 ms or greater hit, and Ethernet traffic will take about a 3 to 4 minute hit due to STP recalculation. After all cards have booted, the active XCVT boots again to ensure that all circuits are updated correctly. Once the active XCVT finishes this final reboot and all alarms clear you can safely proceed to the next step.
Step 9 Shut down and restart your Netscape or Internet Explorer browser.
Step 10 Reconnect to CTC using the IP address from Step 2. The new CTC applet for Release 2.2.2 uploads. This applet gives you network visibility while you are upgrading.
Note Only activate one node at a time.
Step 11 Log into each of the remaining nodes and perform the following procedures, one node at time. Each of these procedures must be performed for every node that has TCC+ cards and is running software Release 2.2.x After each node is finished, you must log out of your CTC session in Netscape to download the new Java plug-ins from the ONS 15454 node. Allow each node to finish (all alarms cleared for 10 minutes) before upgrading the next node:
• Run the Script (Release 2.2.0 only)
Step 12 After activating the last node (the node connected to your workstation) wait for the system to reboot.
Note Be patient. The system might take several minutes to reboot.
Release the span lockouts on all BLSR nodes after the new software load is activated on all nodes.
Step 1 In CTC node view, click the Maintenance > Ring tabs.
Step 2 Select the direction where the lockout is active.
Step 3 Select Clear.
Step 4 Click Apply to activate the command.
Step 5 You might need to invoke the ring map table and accept it to clear Default K byte or Node ID mismatch alarms. Go to the Ring tab and click the Ring Map button. Accept the ring map.
The upgrade procedure can cause the Date setting to change.
Step 1 In CTC node view, click the Provisioning > General tabs.
Step 2 Set the correct date and click Apply.
Step 3 Repeat Steps 1 and 2 for each remaining node.
Spare TCC+ Units
All spare TCC+ units should be upgraded to CTC Release 2.2.2.
To upgrade a spare TCC+, place it in the standby slot of a node running Release 2.2.2. The card will upgrade automatically from the active TCC+.
XC to XCVT Upgrade
This procedure explains how to replace dual XC cards with dual XCVT cards without affecting traffic.
The procedure requires that the ONS 15454 is running CTC Release 2.2.0 or later. The node also needs two XC cards installed and two XCVT cards available.
Step 1 Determine the standby XC card. The ACT/STBY LED of the standby XC card is yellow and the ACT/STBY LED of the active card is green.
You can also put the mouse cursor over the card graphic in CTC to reveal a tooltip displaying Active/Standby status.
Step 2 Unlatch the top and bottom ejector levers of the STANDBY XC card. Remove the card from the slot and put it away.
Step 3 Insert the first XCVT into the empty slot and latch the ejectors.
The red FAIL LED on the card illuminates, blinks for several seconds, then turns off. The ACT/STBY LED turns yellow and stays on.
Step 4 In CTC node view click the Maintenance > XC Cards tabs.
Step 5 Choose Manual from the menu for the Slot X on the active XC card.
Step 6 Click Apply.
A minor alarm appears on the manually-switched slot.
Step 7 On the same slot, choose Clear from the pull-down menu to remove the manual operation.
Step 8 Click Apply.
The XCVT should now be active as indicated by the green ACT/STBY LED.
Step 9 Remove the second XC card after verifying that it is the standby card.
Step 10 Replace the second XC card with the second XCVT card and allow it to boot up.
Revert to Previous Load (TCC+ ONLY)
Before upgrading from Release 2.2.x to Release 2.2.2 software, you must back up the current database at all nodes in the network (this is part of the "Upgrade the Software" section). Cisco highly 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 procedure.
Revert to Protect Load
Step 1 Record the IP address of the node.
Step 2 From the node view, right-click the standby TCC+ and choose Reset. An "Are You Sure" dialog box appears asking you to confirm the choice.
Step 3 Click Yes. The standby TCC+ reboots.
Step 4 Wait for the TCC+ to finish rebooting (this will take approximately 4 minutes).
Step 5 From the node view, click the Maintenance > Software tabs.
Step 6 Verify that the protect software displays 2.2.x (the release you were upgrading from).
Step 7 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 8 Click OK. This begins the revert and drops the connection to the node.
Step 9 After reverting the node, wait until the software upgrade finishes at that node before continuing.
Note Be patient. The system reboot might take up to 30 minutes to complete.
Step 10 Shut down your Netscape or Internet Explorer browser.
Step 11 Wait one minute before restoring another node.
Step 12 After reverting all of the nodes in the network, restart the browser and log back into the last node that was reverted with the IP address that you recorded in Step 1. This uploads the appropriate CTC applet for Release 2.2.x to your workstation.
Manually Restore the Database
In extreme cases it can be necessary to restore the pre-upgrade database.
Caution Do not perform these steps unless you attempted a software revert and it failed.
Caution This process is traffic affecting and should be performed during a service window.
Step 1 From the CTC node view, click the Maintenance > Database tabs.
Step 2 Click Backup. The "Open..." dialog box opens.
Step 3 Select the previously-saved file and choose Open.
The database will be restored and the TCC+s will reboot.
Step 4 Once the TCC+s have rebooted, log back into CTC and verify that the database is restored.
Wait one minute before restoring the next node.
