Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.


This chapter explains how to upgrade cross-connect cards, DS3-12 and DS3N-12 cards, and optical spans for the Cisco ONS 15454.

Note The TCC2 card does not carry any software other than Software R4.0. You will not be able to revert to a software release earlier than Software R4.0 with TCC2 cards installed.



Note Downgrade procedures from TCC2 cards to TCC+ cards are not supported. Contact Cisco Technical Assistance Center (TAC) at 1-800-553-2447 for more information.



Step 1 Complete the "DLP-A60 Log into CTC" task on page 3-23. If you are already logged in, continue with Step 2.

Step 2 Verify that the LAN wires on the backplane are installed properly. The TCC2 card does not autodetect miswired LAN connections. If a LAN connection is miswired, a "LAN Connection Polarity Reversed" condition appears. See the "DLP-A21 Install LAN Wires on the Backplane" task on page 1-38 for instructions.

Step 3 Verify that the node you are upgrading has ONS 15454 Software R4.0 installed. The software version is displayed in the upper left corner of the window.

Step 4 Complete the "NTP-A108 Back Up the Database" procedure on page 15-8 before beginning the upgrade.

Step 5 Physically replace the standby TCC+ card on the ONS 15454 with a TCC2 card.

a. Check the LED on the faceplate. The ACT/STBY LED on the faceplate of the TCC+/TCC2 card indicates whether the card is in active or standby mode. A green ACT/STBY LED indicates an active card and an amber light indicates a standby card.

b. Open the standby TCC+ card ejectors.

c. Slide the card out of the slot. This raises the IMPROPRMVL alarm which will clear when the upgrade is complete.

d. Open the ejectors on the TCC2 card to be installed.

e. Slide the TCC2 card into the slot along the guide rails.

f. Close the ejectors.

g. In CTC node view, Ldg (loading) appears on the recently installed TCC2 card.


Note The MEA (card mismatch) alarm appears because CTC recognizes a mismatch between TCC card types. Disregard this alarm; it clears by the end of the procedure.



Note It takes approximately 10 minutes for the active TCC+ card to transfer the database to the newly-installed TCC2 card. During this operation, the LEDs on the TCC2 flash Fail and then the active/standby LED flashes. When the transfer completes, the TCC2 card reboots and goes into standby mode after approximately three minutes. Do not remove the card from the shelf during a database transfer.



Caution If your active TCC+ card resets during the upgrade before the new TCC2 card has come to a full standby mode, remove the new TCC2 card immediately.

Step 6 When the newly installed TCC2 card is in standby, go to the active TCC+ and right-click the card.


Note You can no longer revert to a software version prior to Software R4.0 once you switch the standby TCC2 card to the active TCC2 card.


Step 7 From the pull-down menu, click Reset Card.

Wait for the TCC+ card to reboot. The ONS 15454 switches the standby TCC2 card to active mode. The TCC+ card verifies that it has the same database as the TCC2 card and then switches to standby.

Step 8 Verify that the remaining TCC+ card is now in standby mode (the ACT/STBY LED changes to amber).

Step 9 Physically replace the remaining TCC+ card with the second TCC2 card.

a. Open the TCC+ card ejectors.

b. Slide the card out of the slot. This raises the MEA alarm, which will clear when the upgrade is complete.

c. Open the ejectors on the TCC2 card.

d. Slide the TCC2 card into the slot along the guide rails.

e. Close the ejectors.

The ONS 15454 boots up the second TCC2 card. The second TCC2 card must also copy the database, which can take approximately 10 minutes. Do not remove the card from the shelf during a database transfer.

Step 10 If power-related alarms occur after the second TCC2 card is installed, check the voltage on the backplane. See the "DLP-A33 Measure Voltage" task on page 1-61 for instructions. Refer to the Cisco ONS 15454 Troubleshooting Guide for information on clearing alarms.

Stop. You have completed this procedure.

Caution Protect cards must be upgraded before working cards because working cards cannot have more capabilities than their protect card.


Note During the upgrade some minor alarms and conditions display and then clear on their own; however, there should be no Service-Affecting (SA, Major, or Critical) alarms. If any service-affecting alarms occur, Cisco recommends backing out of the procedure. See the "DLP-A183 Downgrade a DS3-12E/DS3NE Card to a DS3-12/DS3N-12 Card" task.



Step 1 Determine if the card you are upgrading is protected or unprotected:

a. A protected card will be listed under Protection Groups in the Maintenance > Protection tabs. The slot, port and status (i.e., Protect/Standby, Working/Active) of each card will be listed under Selected Group.

b. An unprotected card will not be listed under Protection Groups/Selected Group in the Maintenance > Protection tabs.

Step 2 If the card you are upgrading is unprotected, skip to Step 3 and ignore references to the protect card and protect slot. If the card you are upgrading is protected, use the "DLP-A287 Switch 1+1 Traffic" task to put a Force switch on the protect card.


Note Traffic will be lost during an upgrade on an unprotected card.


Step 3 Physically remove the protect DS3-12 or the protect DS3N-12 card:

a. Open the DS3-12 or DS3N-12 card ejectors.

b. Slide the card out of the slot. This raises the IMPROPRMVL alarm, which will clear when the upgrade is complete.

Step 4 Right-click the protect slot and choose Change Card from the pull-down menu.

Step 5 Choose the new card (DS3-12E or DS3N-12E) from the Change to: pull-down menu.

NTP-A94 Upgrade Optical Spans Automatically

Purpose

This task upgrades two-fiber BLSR spans, four-fiber BLSR spans, path protection configuration spans, and 1+1 protection group spans. The Span Upgrade Wizard only supports OC-N span upgrades. It does not support electrical upgrades.

Tools/Equipment

Higher-rate cards

Compatible hardware necessary for the upgrade (For example XC10G cards and OC-48 any slot cards)

Prerequisite Procedures

DLP-A60 Log into CTC, page 3-23

The span upgrade procedure requires at least two technicians (one at each end of the span) who can communicate with each other during the upgrade.

Security Level

Provisioning or higher



Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.



Note Optical transmit and receive levels should be in their acceptable range as shown in the specifications section for each card in the Cisco ONS 15454 Reference Manual.



Caution Do not perform any other maintenance operations or add any circuits during a span upgrade.


Note An OC-3 to eight-port OC-3 span upgrade, or an OC-12 to four-port OC-12 span upgrade can only be performed from multispeed slots (Slots 1 to 4 and 14 to 17) because the OC3-8 and OC12-4 card can only be installed in multispeed slots. Ensure that the OC-3 and OC-12 cards are in multispeed slots before performing a span upgrade to the OC3-8 and OC12-4. The four OC-3 ports will be mapped to Ports 1 to 4 on the eight-port OC-3 card. The OC-12 port will be mapped to Port 1 on the four-port OC-12 card.



Note BLSR protection channel access (PCA) circuits, if present, will remain in their existing STSs. Therefore, they will be located on the working path of the upgraded span and will have full BLSR protection. To route PCA circuits on protection channels in the upgraded span, delete and recreate the circuits after the span upgrade. For example, if you upgrade an OC-48 span to an OC-192, PCA circuits on the protection STSs (STSs 25 to 48) in the OC-48 BLSR will remain in their existing STSs (STSs 25 to 48) which are working, protected STSs in the OC-192 BLSR. Deleting and recreating the OC-48 PCA circuits moves the circuits to STSs 96 to 192 in the OC-192 BLSR. To delete circuits, see the "NTP-A152 Delete Circuits" procedure on page 9-16. To create circuits, see Chapter 6, "Create Circuits and VT Tunnels."



Step 1 Determine the type of span you need to upgrade and make sure you have the necessary cards.Valid span upgrades include:

Four-port OC-3 to eight-port OC-3

Single-port OC-12 to four-port OC-12

Single-port OC-12 to OC-48

Single-port OC-12 to OC-192

OC-48 to OC-192


Caution You cannot upgrade a four-port OC-12 span. If the ring contains any OC-12-4 cards and you need to upgrade all the spans in the ring, you will need to downgrade the OC-12-4 card to a single-port OC-12 card (which is not possible unless only one port on the OC12-4 card is being used).

Step 2 Complete the "DLP-A60 Log into CTC" task on page 3-23. If you are already logged in, continue with Step 3.


Note The Span Upgrade option will only be visible and available if the hardware necessary for the upgrade is present; for example, no upgrade is possible from an OC48 span unless XC10G cards are installed in the nodes at both ends of the span.


Step 3 Ensure that no alarms or abnormal conditions (regardless of severity), including LOS, LOF, AIS-L, SF, SD, and FORCED-REQ-RING are present. See the "DLP-A298 Check the Network for Alarms and Conditions" task on page 13-3 for instructions.


Note During the upgrade/downgrade some minor alarms and conditions display and then clear automatically. No service-affecting alarms (SA, Major, or Critical) should occur other than BLSROSync, which will clear when the upgrade/downgrade of all nodes is complete. If any other service-affecting alarms occur, Cisco recommends backing out of the procedure.
A four-node BLSR can take up to five minutes to clear all of the BLSROSync alarms. Allow extra time for a large BLSR to clear all of the BLSROSync alarms.


Step 4 In network view, right-click the span you want to upgrade.

Step 5 Choose Span Upgrade from the pull-down menu (Figure 12-2).

Figure 12-2 Span Upgrade Pull-Down Menu

Step 6 The first Span Upgrade dialog box appears (Figure 12-3). Follow the instructions on the dialog box and the wizard will lead you through the rest of the span upgrade.


Note The Back button is only enabled on Step 2 of the wizard; because you cannot back out of an upgrade via the wizard, close the wizard and initiate the manual procedure if you need to back out of the upgrade at any point beyond Step 2.


Figure 12-3 Span Upgrade Wizard


Caution As indicated by the wizard, when installing cards you must wait for the cards to boot up and become active before proceeding to the next step.

Note If you install OC-192 cards, a disabled OC-192 laser causes an LOS alarm to be reported for each OC-192 slot. Enable the OC-192 laser by setting the safety key lock on the OC-192 faceplate to the ON position (labeled 1).



Note Remember to attach the fiber after installing the OC-N cards.



Note The span upgrade process resets the line's CV-L threshold to factory default. The CV-L threshold is reset because the threshold is dependent on line rate.


Step 7 Repeat Steps 4 through 6 for additional spans in the ring.

Stop. You have completed this procedure.

Note In this context the word "span" represents the optical path between two nodes. The words "span endpoint" represent the nodes on each end of a span.



Note If any of the cross-connect cards reboot during the span upgrade, you must reset each one when the span upgrade procedure is complete for all the nodes in the ring.



Step 1 Determine the type of span you need to upgrade and make sure you have the necessary cards.Valid span upgrades include:

Four-port OC-3 to eight-port OC-3

Single-port OC-12 to four-port OC-12

Single-port OC-12 to OC-48

Single-port OC-12 to OC-192

OC-48 to OC-192


Caution You cannot upgrade a four-port OC-12 span. If the ring contains any OC-12-4 cards and you need to upgrade all the spans in the ring, you will need to downgrade the OC-12-4 card to a single-port OC-12 card (which is not possible unless only one port on the OC12-4 card is being used).

Step 2 Complete the "DLP-A60 Log into CTC" task on page 3-23. If you are already logged in, continue with Step 3.

Step 3 Ensure that no alarms or abnormal conditions (regardless of severity), including LOS, LOF, AIS-L, SF, SD, and FORCED-REQ-RING are present. See the "DLP-A298 Check the Network for Alarms and Conditions" task on page 13-3 for instructions.

No service-affecting alarms (SA, Major, or Critical) should occur other than BLSROSYNC, which will clear when the upgrade/downgrade of all nodes is complete. If any other service-affecting alarms occur, Cisco recommends backing out of the procedure.
A four-node BLSR can take up to five minutes to clear all of the BLSROSYNC alarms. Allow extra time for a large BLSR to clear all of the BLSROSYNC alarms. Refer to the Cisco ONS 15454 Troubleshooting Guide for information about alarms.


Step 4 Complete a manual upgrade task if you need to perform error recovery for the Span Upgrade Wizard or back out of a span upgrade (downgrade):

Complete the "DLP-A293 Perform a Manual Span Upgrade on a Two-Fiber BLSR" task to upgrade an optical span manually within a two-fiber BLSR.

Complete the "DLP-A294 Perform a Manual Span Upgrade on a Four-Fiber BLSR" task to upgrade an optical span manually within a four-fiber BLSR.

Complete the "DLP-A295 Perform a Manual Span Upgrade on a Path Protection Configuration" task to upgrade an optical span manually within a two-fiber path protection configuration.

Complete the "DLP-A296 Perform a Manual Span Upgrade on a 1+1 Protection Group" task to upgrade an optical span manually within a 1+1 protection group.

Complete the "DLP-A297 Perform a Manual Span Upgrade on an Unprotected Span" task to upgrade an unprotected optical span manually.


Note The span upgrade process resets the line's CV-L threshold to factory default. The CV-L threshold is reset because the threshold is dependent on line rate.



Note The Span Upgrade option will only be visible and available if the hardware necessary for the upgrade is present; for example, no upgrade is possible from an OC48 span unless XC10G cards are installed in the nodes at both ends of the span.



Note An OC-3 to eight-port OC-3 span upgrade, or an OC-12 to four-port OC-12 span upgrade can only be performed from multispeed slots (Slots 1 to 4 and 14 to17) because the OC3-8 and OC12-4 card can only be installed in multispeed slots. Ensure that the OC-3 and OC-12 cards are in multispeed slots before performing a span upgrade to the OC3-8 and OC12-4. The four OC-3 ports will be mapped to Ports 1-4 on the eight-port OC-3 card. The OC-12 port will be mapped to Port 1 on the four-port OC-12 card.

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.



Caution Do not perform any other maintenance operations or add any circuits during a span upgrade.


Note All spans connecting the nodes in a BLSR must be upgraded before the bandwidth is available.



Note BLSR protection channel access (PCA) circuits, if present, will remain in their existing STSs. Therefore, they will be located on the working path of the upgraded span and will have full BLSR protection. To route PCA circuits on protection channels in the upgraded span, delete and recreate the circuits after the span upgrade. For example, if you upgrade an OC-48 span to an OC-192, PCA circuits on the protection STSs (STSs 25 to 48) in the OC-48 BLSR will remain in their existing STSs (STSs 25 to 48) which are working, protected STSs in the OC-192 BLSR. Deleting and recreating the OC-48 PCA circuits moves the circuits to STSs 96 to 192 in the OC-192 BLSR. To delete circuits, see the "NTP-A152 Delete Circuits" procedure on page 9-16. To create circuits, see Chapter 6, "Create Circuits and VT Tunnels."



Step 1 Apply a Force switch to both span endpoints (nodes) on the span that you will upgrade first. See the "DLP-A303 Initiate a BLSR Force Switch - Ring" task on page 14-7.


Note A Force switch request on a span or card causes CTC to raise a FORCED-REQ condition. It is informational only; the condition will clear when the Force switch is cleared.


Step 2 Remove the fiber from both endpoints and ensure that traffic is still running.

Step 3 Remove the OC-N cards from both endpoints.

Step 4 From both endpoints, in node view right-click each OC-N slot and choose Change Card.

Step 5 In the Change Card dialog box, choose the new OC-N card type.

Step 6 Click OK.

Step 7 Before attaching the fiber to the newly installed OC-N cards, check that the transmit signal falls within the acceptable range. Install the new OC-N cards in both endpoints and attach the fiber to the cards. Wait for the IMPROPRMVL alarm to clear and the cards to become active.


Note If you install OC-192 cards, a disabled OC-192 laser causes an LOS alarm to be reported for each OC-192 slot. Enable the OC-192 laser by setting the safety key lock on the OC-192 faceplate to the ON position (labeled 1).


Step 8 When cards in both endpoint nodes have been successfully upgraded and all the facility alarms (LOS, SD or SF) are cleared, remove the forced switch from both endpoints on the upgraded span. Seethe "DLP-A194 Clear a BLSR Force Switch - Ring" task on page 14-9.

The Force switch clears and traffic is running. If you have lost traffic, perform a downgrade. Repeat this task to downgrade but choose a lower-rate card in Step 5.

Step 9 Repeat this task for each span in the BLSR. When you are done with each span, the upgrade is complete.

Step 10 Return to your originating procedure (NTP).
