Note This procedure applies only to XC10G cards that are installed in nodes running Software R4.0 and later.



Note You cannot upgrade from an XC10G to an XCVXL 2.5G if an STM-64 card is preprovisioned or installed in the node. The XCVXL 2.5G works only 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 3-24. 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 that identifies the card as Active or Standby.


Step 4 Physically replace the standby XC10G card 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 becomes amber and remains 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 XCVXL card that you 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 XC10G card from the shelf and insert the second XCVXL card into the empty cross-connect slot:

a. Open the XC10G card ejectors.

b. Slide the XC10G card out of the slot.

c. Open the ejectors on the XCVXL card.

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

e. Close the ejectors.

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

Stop. You have completed this procedure.

NTP-D94 Upgrade STM-N Cards and Spans Automatically

Purpose

This procedure upgrades cards, STM-N speeds within MS-SPRings, SNCPs, and 1+1 (linear) 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 table in "NTP-D19 Install Fiber-Optic Cables on STM-N Cards" procedure on page 2-30.



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 card works only with card speeds up to STM-16.


Step 2 Complete the "DLP-D60 Log into CTC" task on page 3-24. 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 14-1).

Figure 14-1 Span Upgrade Drop-Down Menu

Step 6 The first Span Upgrade dialog box appears (Figure 14-2). 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 14-2 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

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.

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 table in the "NTP-D19 Install Fiber-Optic Cables on STM-N Cards" procedure on page 2-30.



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 works only with card speeds up to STM-16.


Step 2 Complete the "DLP-D60 Log into CTC" task on page 3-24. 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.
