Upgrade Cards and Spans


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


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.

Security Level

Maintenance or higher



Note The UNEQ-P alarm is raised during a cross-connect card upgrade if you have E100T-12/E1000-2 cards installed in the node. The alarm will clear within a few seconds.



Caution Always upgrade the standby cross-connect card. Removing an active cross-connect card can cause a protection switch unless a lockout is in place. If the standby card is being upgraded, a lockout is unnecessary.


Step 1 Complete the "DLP-A60 Log into CTC" task at the node where you will perform the upgrade. If you are already logged in, continue with Step 2.

Step 2 According to local site practice, complete the "A108 Back Up the Database" procedure.

Step 3 Determine the standby XC card. The ACT/STBY LED of the standby XC card is amber, while the ACT/STBY LED of the active XC card is green.

Step 4 Physically replace the standby XC card with an XCVT card:

a. Open the XC card ejectors.

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

c. Open the ejectors on the XCVT card.

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

e. Close the ejectors.

On the XCVT card the FAIL LED above the ACT/STBY LED becomes red, blinks for several seconds, and turns off. The amber ACT/STBY LED turns on.

Step 5 In node view, click the Maintenance > Cross-Connect tabs.

Step 6 From the Cross Connect Cards menu, choose Switch.

Step 7 Click Yes on the Confirm Switch dialog box. Traffic switches to the XCVT card inserted in Step 4. The ACT/STBY LED on this card changes from amber to green.


Note The Interconnection Equipment Failure alarm appears, but it will clear when the upgrade procedure is complete and the node has matching cross-connect cards installed.


Step 8 Physically remove the now standby XC card from the shelf and insert the second XCVT card into the empty XC slot:

a. Open the XC card ejectors.

b. Slide the XC card out of the slot.

c. Open the ejectors on the XCVT.

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

e. Close the ejectors.

The upgrade is complete when the second XCVT card boots up and becomes the standby XCVT.

Security Level

Provisioning or higher



Note Upgrades must be performed between two N-type cards or two non-N-type cards. You cannot upgrade between an N-type card and a non-N-type card. When physically replacing a card, the new card must be in the same slot as the old card. The DS3-12E card upgrade supports 1:1 and 1:N protection schemes. The procedure is non-service affecting for protected cards; that is, the upgrade will cause a switch less than 50 ms in duration.



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 appear and then clear on their own; however, there should be no Service-Affecting (SA, Major, or Critical) alarms if you are upgrading protected cards. (Upgrading an unprotected card can be service affecting.) If any service-affecting alarms occur, Cisco recommends backing out of the procedure. See the "A254 Downgrade a DS3-12E/DS3NE Card to a DS3-12/DS3N-12 Card" procedure.



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

Step 2 According to local site practice, complete the "A108 Back Up the Database" procedure.

Step 3 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 (that is, Protect/Standby, Working/Active) of each card will be listed in the Selected Group.

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


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

Step 4 If the card you are upgrading is unprotected, skip this step and go to Step 5 and ignore references to the protect card and protect slot. If the card you are upgrading is protected, make sure the protect card is not active. If the card status is Protect/Active, perform a switch so that the working card becomes active:

a. Double-click the protection group.

b. Click the Protect/Active card.

c. Click Switch.

d. Click Yes in the confirmation dialog box.

Step 5 Physically remove the protect DS3-12 or the protect DS3N-12 card:

NTP-A94 Upgrade OC-N Cards and Spans Automatically

Purpose

This procedure upgrades cards, two-fiber BLSR spans, four-fiber BLSR spans, path protection 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)

Attenuators might be needed for some applications

Prerequisite Procedures

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.

Required/As Needed

As needed

Onsite/Remote

Onsite

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.



Caution Do not perform any other maintenance operations, such as facility or terminal loopbacks, or add any circuits during a card or span upgrade.


Note OC-N transmit and receive levels should be in their acceptable range as shown in the specifications for each card in the "A247 Install Fiber-Optic Cables on OC-N Cards" procedure.



Note During the upgrade, the IMPROPRMVL alarm may be raised. It will clear automatically.



Note A four-port OC-3 to eight-port OC-3 upgrade, or an OC-12 to four-port OC-12 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 "A278 Modify and Delete Overhead Circuits" procedure. To create circuits, see "Create Circuits and VT Tunnels."



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

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

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

Valid span upgrades include:

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 OC12-4 cards and you need to upgrade all the spans in the ring, you will need to downgrade the OC12-4 card to a single-port OC-12 card (which is only possible if one port on the OC12-4 card is being used).

Step 2 Complete the "DLP-A60 Log into CTC" task. 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 OC-48 span unless XC10G cards are installed in the nodes at both ends of the span.


According to local site practice, complete the "A108 Back Up the Database" procedure.

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 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 drop-down menu.

Step 6 The first Span Upgrade dialog box appears (Figure 14-1). 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 14-1 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 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.


NTP-A95 Upgrade OC-N Spans Manually

Purpose

This procedure upgrades OC-N speeds within BLSRs, path protection, and 1+1 protection groups by upgrading OC-N cards. 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).

Tools/Equipment

Replacement cards

Prerequisite Procedures

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

Provisioning or higher



Note OC-N card transmit and receive levels should be in their acceptable range as shown in the specifications section for each card in the "A247 Install Fiber-Optic Cables on OC-N Cards" procedure.



Note In this context the word "span" represents the OC-N 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. If you are already logged in, continue with Step 3.

Step 3 According to local site practice, complete the "A108 Back Up the Database" procedure.

Step 4 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 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. Refer to the Cisco ONS 15454 Troubleshooting Guide for information about alarms.


Step 5 Complete the appropriate task:

A293 Perform a Manual Span Upgrade on a Two-Fiber BLSR

A294 Perform a Manual Span Upgrade on a Four-Fiber BLSR

A295 Perform a Manual Span Upgrade on a Path Protection

A296 Perform a Manual Span Upgrade on a 1+1 Protection Group

A297 Perform a Manual Span Upgrade on an Unprotected Span


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 A four-port 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.


Stop. You have completed this procedure.


DLP-A293 Perform a Manual Span Upgrade on a Two-Fiber BLSR

Purpose

This task upgrades a two-fiber BLSR span to a higher OC-N rate. To downgrade a span, repeat this task but choose a lower-rate card in Step 5.

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 "A278 Modify and Delete Overhead Circuits" procedure. To create circuits, see "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 Ring Switch" task.

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 Complete the "A16 Install the OC-N Cards" procedure to install the new OC-N cards in both endpoints.

Step 8 Verify that the transmit and receive signals fall within the acceptable range. See Table 2-5 for OC-N card transmit and receive levels. If the receive level falls outside the acceptable range for that card, attenuate accordingly.

Step 9 Complete the "DLP-A44 Install Fiber-Optic Cables for BLSR Configurations" task to attach the fiber to the cards. Wait for the IMPROPRMVL alarm to clear and the cards to become active.

Step 10 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. See the "DLP-A194 Clear a BLSR Force Ring Switch" task.

Step 11 Perform an exercise ring test to check the BLSR ring functionality without switching traffic. See the "DLP-A217 BLSR Exercise Ring Test" task.

Step 12 Repeat this task for each span in the BLSR. When you are done with each span, the upgrade is complete.

Step 13 Return to your originating procedure (NTP).


DLP-A294 Perform a Manual Span Upgrade on a Four-Fiber 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 "A278 Modify and Delete Overhead Circuits" procedure. To create circuits, see "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 Ring Switch" task.

Step 2 Remove the fiber from both working and protect cards at both span endpoints (nodes) and ensure that traffic is still running.

Step 3 Remove the OC-N cards from both end points.

Step 4 For both ends of the span 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 Complete the "A16 Install the OC-N Cards" procedure to install the new OC-N cards in both endpoints.

Step 8 Verify that the transmit signal falls within the acceptable range. See Table 2-5 for OC-N card transmit and receive levels.

Step 9 Complete the "DLP-A44 Install Fiber-Optic Cables for BLSR Configurations" task to attach the fiber to the cards. Wait for the IMPROPRMVL alarm to clear and the cards to become active.

Step 10 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 (nodes) on the upgraded span. See "DLP-A194 Clear a BLSR Force Ring Switch" task.

Step 11 Perform an exercise ring test to check the BLSR ring functionality without switching traffic. See the "DLP-A217 BLSR Exercise Ring Test" task.

Step 12 Repeat these steps for each span in the BLSR. When all spans in the BLSR have been upgraded, the ring is upgraded.

Step 13 Return to your originating procedure (NTP).
