Note You cannot upgrade from an XC10G to an XCVXL 2.5G if an STM-64 card is pre-provisioned or installed in the node. The XCVXL 2.5G only works with card speeds up to STM-16.



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



Step 1 Complete the "DLP-D60 Log into CTC" task on page 3-23. If you are already logged in, continue with Step 2.

Step 2 Verify that the node you are upgrading has TCC2 cards installed.

Step 3 Determine the standby XC10G card. The ACT/STBY LED of the standby XC10G card is amber, and the ACT/STBY LED of the active XC10G card is green.


Note You can also place the cursor on the card graphic in CTC to display a dialog. This display identifies the card as XC10G: Active or XC10G: Standby.


Step 4 Physically replace the standby XC10G card on the ONS 15454 SDH with an XCVXL card:

a. Open the XC10G 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 XCVXL card.

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

e. Close the ejectors.

On the XCVXL card the fail LED above the ACT/STBY LED becomes red, blinks for approximately a minute, and turns off. The ACT/STBY LED turns amber and remains illuminated.

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 XCVXL card you inserted in

NTP-D208 Upgrade the TCC-I Card to the TCC2 Card

Purpose

This procedure upgrades the TCC-I card to the TCC2 card. The TCC2 card supports ONS 15454 SDH Software R4.0 and later. The TCC-I card supports ONS 15454 SDH Software R3.4 and earlier. The TCC-I card can only be used with Software R4.0 during the upgrade process.

Tools/Equipment

Two SDH TCC2 cards

Prerequisite Procedures

None

Required/As Needed

As needed

Onsite/Remote

Onsite

Security Level

Maintenance or higher



Note You will not be able to revert to a software release earlier than Software R4.0 with TCC2 cards installed.



Note The TCC-I card can be used with Software R4.0 only for TCC2 card upgrade purposes. For example, during a TCC2 card upgrade, some nodes on your network could have Software R4.0 with TCC-I cards installed, while other nodes have Software R4.0 with TCC2 cards installed. TCC-I cards running Software R4.0 are not supported beyond the TCC2 upgrade process because performance issues such as switch times cannot be guaranteed.



Note Downgrade procedures from TCC2 cards to TCC-I cards are not supported. Contact Cisco Technical Assistance Center (TAC) for more information.



Step 1 Complete the "DLP-D60 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 MIC-C/T/P are installed properly. The TCC2 does not autodetect miswired LAN connections. If a LAN connection is miswired, a "LAN Connection Polarity Reversed" condition appears. See "DLP-D326 Install LAN Wires on the MIC-C/T/P" task on page 1-34 for instructions.

Step 3 Verify that the node you are upgrading has ONS 15454 SDH Software R4.0 installed. The software version is displayed in the upper left corner of the window. To upgrade software, refer to the Cisco ONS 15454 SDH Software Upgrade Guide.

Step 4 Complete the "NTP-D108 Back Up the Database" procedure on page 17-8.

Step 5 Physically replace the standby TCC-I card on the ONS 15454 SDH with a TCC2 card.

a. Check the LED on the faceplate. The ACT/STBY LED on the faceplate of the TCC-I or 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-I 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.


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


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-I 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.


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


Note You cannot revert to a software release prior to Software R4.0 after you switch the standby TCC2 card to the active TCC2 card.


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

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

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

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

a. Open the TCC-I 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 SDH 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. See the "DLP-D33 Measure Voltage" task on page 1-47 for instructions. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for information on clearing alarms.

Step 11 Perform this procedure again until all nodes on your network are running TCC2 cards with Software R4.0 or later installed.

Stop. You have completed this procedure.


NTP-D94 Upgrade Optical Spans Automatically

Purpose

This procedure upgrades STM-N speeds within MS-SPRings, SNCPs, and 1+1 protection groups using the Span Upgrade Wizard.

Tools/Equipment

Replacement cards

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.



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 SDH Reference Manual.



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


Note An STM-1 to eight-port STM-1 span upgrade, or an STM-4 to four-port STM-4 span upgrade can only be performed from multispeed slots (slots 1-4 and 14-17) because the STM1-8 and STM4-4 card can only be installed in multispeed slots. Ensure that the STM-1 and STM-4 cards are in multispeed slots before performing a span upgrade to the STM1-8 and STM4-4. The four STM-1 ports will be sequentially mapped to ports 1-4 on the eight-port STM-1 card. The STM-4 port will be mapped to port 1 on the four-port STM-4 card.



Step 1 Determine the span upgrade you need to perform. Valid span upgrades include:

Four-port STM-1 to eight-port STM-1

Single-port STM-4 to four-port STM-4

Single-port STM-4 to STM-16

Single-port STM-4 to STM-64

STM-16 to STM-64


Note You cannot upgrade a four-port STM-4 span. If the ring contains any STM4-4 cards and you want to upgrade the entire ring, you will have to downgrade the STM4-4 card to a single-port STM-4 card (which is not possible unless only one port on the STM4-4 card is being used).



Note Do not upgrade an STM-16 to an STM-64 if you have XCVXL 2.5Gs installed. The XCVXL 2.5G only works with card speeds up to STM-16.


Step 2 Complete the "DLP-D60 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-D298 Check the Network for Alarms and Conditions" task on page 15-3 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 MSSP-OSYNC, 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 MS-SPRing can take up to five minutes to clear all of the MSSP-OSYNC alarms. Allow extra time for a large MS-SPRing to clear all of the MSSP-OSYNC alarms.


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

Step 5 Choose Span Upgrade from the drop-down menu (Figure 14-2).

Figure 14-2 Span Upgrade Drop-Down Menu

Step 6 The first Span Upgrade dialog box appears (Figure 14-3). Follow the instructions in 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 14-3 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 STM-64 cards, a disabled STM-64 laser causes an LOS alarm to be reported for each STM-64 slot. Enable the STM-64 laser by setting the safety key lock on the STM-64 faceplate to the ON position (labeled 1).



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


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


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.


Stop. You have completed this procedure.


NTP-D95 Upgrade Optical Spans Manually

Purpose

This procedure upgrades STM-N speeds within MS-SPRings, SNCPs, and 1+1 protection groups by upgrading STM-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.

Required/As Needed

As needed

Onsite/Remote

Onsite

Security Level

Provisioning or higher



Caution If you want to upgrade all of the spans in a ring, determine if there are any four-port STM-4 cards in the ring. If the ring contains any STM4-4 cards and you wish to continue with the upgrade, you will have to downgrade the STM4-4 card to a single-port STM-4 card (which is not possible unless only one port on the STM4-4 card is being used).


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



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 span upgrade you need to perform. Valid span upgrades include:

Four-port STM-1 to eight-port STM-1

Single-port STM-4 to four-port STM-4

Single-port STM-4 to STM-16

Single-port STM-4 to STM-64

STM-16 to STM-64


Note Do not upgrade an STM-16 to an STM-64 if you have XCVXL 2.5Gs installed. The XCVXL 2.5G only works with card speeds up to STM-16.


Step 2 Complete the "DLP-D60 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-D298 Check the Network for Alarms and Conditions" task on page 15-3 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 MSSP-OSYNC, 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 MS-SPRing can take up to five minutes to clear all of the MSSP-OSYNC alarms. Allow extra time for a large MS-SPRing to clear all of the MSSP-OSYNC alarms.


Step 4 Complete the appropriate task:

D293 Perform a Manual Span Upgrade on a Two-Fiber MS-SPRing

D294 Perform a Manual Span Upgrade on a Four-Fiber MS-SPRing

D295 Perform a Manual Span Upgrade on an SNCP

D296 Perform a Manual Span Upgrade on a 1+1 Protection Group

D297 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 Span upgrades do not upgrade SDH topologies; for example, 1+1 protection group to a two-fiber MS-SPRing.



Note An STM-1 to eight-port STM-1 span upgrade, or an STM-4 to four-port STM-4 span upgrade can only be performed from multispeed slots (slots 1-4 and 14-17) because the STM1-8 and STM4-4 card can only be installed in multispeed slots. Ensure that the STM-1 and STM-4 cards are in multispeed slots before performing a span upgrade to the STM1-8 and STM4-4. The four STM-1 ports will be sequentially mapped to ports 1-4 on the eight-port STM-1 card. The STM-4 port will be mapped to port 1 on the four-port STM-4 card.


Stop. You have completed this procedure.
