Upgrade Cards and Spans
This chapter explains how to upgrade the Cisco ONS 15327 XTC card and how to upgrade optical speeds within a ring or protection group.
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.
Before You Begin
This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).
1. B229 Upgrade the XTC-14 Card to XTC-28 Card—Complete this procedure as needed to upgrade the XTC-14 card to the XTC-28 card.
2. B94 Upgrade Optical Spans Automatically—Complete this procedure as needed to upgrade optical cards within path protection configurations, BLSRs, and 1+1 protection groups.
3. B95 Upgrade Optical Spans Manually—Complete this procedure as needed to perform error recovery for the Span Upgrade Wizard or back out of a span upgrade (downgrade).
NTP-B229 Upgrade the XTC-14 Card to XTC-28 Card

Note The UNEQ-P alarm might be raised during the upgrade if you have E10/E100-4 cards in the node. The alarm will clear within a few seconds.
Note The MEA (card mismatch) alarm appears because CTC recognizes a mismatch between XTC card types. Disregard this alarm; it clears by the end of the procedure.
Note Downgrade procedures from XTC-28 to XTC-14 are not supported. Contact Cisco Technical Assistance Center (TAC) for more information, see Obtaining Technical Assistance.
Step 1 Complete the "B108 Back Up the Database" procedure before beginning the upgrade.
Step 2 Determine which XTC-14 card is the standby card. An amber ACT/STBY LED on the card faceplate indicates a standby card.
Step 3 Physically replace the standby XTC-14 card on the ONS 15327 with an XTC-28 card:
a. Open the XTC-14 card ejector.
b. Slide the card out of the slot. This raises an IMPROPRMVL alarm which will clear when the upgrade is complete. Ensure that traffic is flowing over the 14 DS-1 ports. Abnormal alarms will indicate if there is a problem with traffic. Ensure that the alarm filter is not selected when you are checking for abnormal alarms.
c. Open the ejector on the XTC-28 card.
d. Slide the XTC-28 card into the slot along the guide rails.
e. Close the ejector and secure the screw.
The ONS 15327 boots up the XTC-28 card. The XTC-28 card must copy the database, which can take approximately 10 minutes. Do not remove the card from the shelf during a database transfer.
The LEDs will flash while the XTC-28 is loading.
Step 4 After the XTC-28 card has finished synchronizing its software and database and is in standby mode, in node view right-click the active XTC-14 and choose Reset from the drop-down menu (Figure 11-1).
Figure 11-1 Resetting the XTC Card
Step 5 Physically replace the remaining XTC-14 card:
a. Open the XTC-14 card ejector.
b. Slide the card out of the slot. This raises an IMPROPRMVL alarm that will clear when the upgrade is complete.
c. Open the ejector on the XTC-28 card.
d. Slide the XTC-28 card into the slot along the guide rails.
e. Close the ejector and secure the screw.
The ONS 15327 boots up the second XTC-28 card. The second XTC-28 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 6 If power-related alarms occur after the second XTC-28 card is installed, check the voltage on the backplane. See the "DLP-B33 Measure Voltage" task on page 1-49 for instructions. Refer to the Cisco ONS 15327 Troubleshooting Guide for information on clearing alarms.
Stop. You have completed this procedure.
NTP-B94 Upgrade Optical Spans Automatically
Purpose
|
This procedure upgrades OC-N speeds within BLSRs, path protection configurations, and 1+1 (linear) protection groups using the Span Upgrade Wizard. Upgrading a span is non-service affecting and will cause no more than three switches, each of which is less than 50 ms in duration.
|
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.

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.
Step 1 Complete the "DLP-B60 Log into CTC" task. If you are already logged in, continue with Step 2.
Step 2 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-B298 Check the Network for Alarms and Conditions" task for instructions.
Step 3 In network view, right-click the span you want to upgrade.
Step 4 Choose Span Upgrade from the drop-down menu.
Step 5 The first Span Upgrade dialog box appears. Follow the instructions on the dialog box and the wizard will lead you through the rest of the span upgrade.
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 The Back button is only enabled in the first screen 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 the second screen.
Note Remember to attach the fiber after installing the OC-N cards. Optical transmit and receive levels should be in their acceptable range as shown in the specifications section for each card in Table 1-6 on page 1-38.
Step 6 Repeat Steps 2 through 5 for additional spans in the ring.
Note The span upgrade process resets the line CV-L threshold to the factory default. The CV-L threshold is reset because the threshold is dependent on the line rate.
Note Span upgrades do not upgrade SONET topologies; for example, a 1+1 protection group to a two-fiber BLSR.
Note During the upgrade some minor alarms and conditions appear and then clear automatically. No service-affecting alarms (SA, Major, or Critical) should occur other than BLSR Out of Sync, which will clear when the upgrade of all nodes is complete. If any other service-affecting alarms occur, Cisco recommends backing out of the procedure.
Extra time may be required to clear all of the Out of Sync alarms depending on the size of the BLSR.
Stop. You have completed this procedure.

Step 1 From the View menu, choose Go to Network View. Verify that all affected spans on the network map are green.
Step 2 Verify that the affected spans do not have active switches on the network map. Span ring switches are graphically displayed on the span with the letters "L" for lockout ring, "F" for FORCE ring, "M" for MANUAL ring, and "E" for EXERCISE ring.
Step 3 A second verification method can be performed from the Conditions tab. Click Retrieve Conditions and verify that no switches are active. Make sure the Filter button is not selected.
Step 4 Click the Alarms tab. Verify that no critical or major alarms are present, nor any facility alarms, such as LOS, LOF, AIS-L, AIS-P, SF, and SD. Make sure the Filter button is not selected.
If trouble is indicated (for example, a major alarm exists), resolve the problem before proceeding. See "Manage Alarms," or, if necessary, refer to the Cisco ONS 15327 Troubleshooting Guide.

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 XTC cards reboot during the span upgrade, you must manually reset each one when the span upgrade procedure is complete for all the nodes in the ring. See the "B113 Reset the XTC Using CTC" procedure for card reset procedures.
Step 1 Determine the type of span you need to upgrade and make sure you have the necessary cards. Valid span upgrades include:
•OC-12 to OC-48
•OC-12 IR to OC-12 LR
•OC-48 IR to OC-48 LR
Step 2 Complete the "DLP-B60 Log into CTC" task. 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-B298 Check the Network for Alarms and Conditions" task for instructions.
Note During the upgrade/downgrade some minor alarms and conditions appear and then clear automatically. No service-affecting alarms (SA, Major, or Critical) should occur other than BLSR Out-of-Sync, 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.
Allow extra time for a large BLSR to clear all of the Out-of-Sync 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-B293 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-B295 Perform a Manual Span Upgrade on a Path Protection" task to upgrade an optical span manually within a path protection.
•Complete the "DLP-B296 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-B297 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 the factory default. The CV-L threshold is reset because the threshold is dependent on the line rate.
Note Span upgrades do not upgrade SONET topologies; for example, a 1+1 protection group to a two-fiber BLSR.
Stop. You have completed this procedure.
DLP-B293 Perform a Manual Span Upgrade on a Two-Fiber BLSR
