Procedure Operation Precautions

During replacement l Wear an ESD wrist strap.l Insert or remove the board

correctly.

l Remove fibers connectedto the board beforereplacement. Connect thefiber back again after theboard is replaced.

l Record the settings of thejumper and DIP switch onthe board.

l Protect the board fromdamage during removaland replacement byfollowing standard ESDprocedures. Avoidlooking directly into fiberoptic cables to help avoideye damage.

After replacement l Check the boardindicators and make surethat the board worksnormally.

l Query related alarms andperformance events byusing the U2000, andmake sure that there is noabnormal alarm.

l Store the replaced boardin an ESD protection bagand attach a maintenancelabel to the bag. The labelmust show the NE nameand include a faultdescription.

l Make sure that the fibersare connected correctly.

l To replace an SCC board,you must re-apply theconfigurations, setperformance monitoringparameters, and back upthe database.

l For a functional boardwith a backup, check ifthe switching is normal.

l For a board without thealarm reporting function,ensure that all devicesconnected to the board areoperating correctly.

Before you replace a board or other hardware functional components of the optical networkequipment, be aware of the following information:

1.1 Specifications and VersionsWhen replacing a board, make sure that the name and version of the new board are consistentwith those of the replaced board.

1.2 LaserWhen you install and maintain equipment, follow the safety precautions described below to helpprevent personal injury or equipment damage. The laser complies with IEC60825.

1.3 Short CircuitExercise caution where you place metallic tools so that you do not cause a short circuit in anyequipment.

During installation and maintenance, follow antistatic procedures to prevent equipment damage:

1.5 Working on Equipment with Power AppliedWhen you perform operations on the equipment when power is applied, ensure that you take thesafety precautions to prevent personal injury or equipment damage.

1.6 Alarm and Safety SymbolsDuring equipment installation and maintenance, observe the precautions indicated by the alarmand safety symbols to help prevent personal injury or equipment damage.

1.7 Correct Board Inserting and RemovingRemoving an in-service board can interrupt services. Perform board hot swapping during off-peak hours.



3

1.1 Specifications and VersionsWhen replacing a board, make sure that the name and version of the new board are consistentwith those of the replaced board.

If the version is inconsistent, you must check whether the boards with different versions can bereplaced. For information about the replacement compatibility between board versions, see theHardware Description.

For OTU boards, the wavelength of the new and replaced boards must be identical. Wavelengthinformation is provided in the bar code on the front panel of the board. For details about the barcode, see the Hardware Description. You can also obtain board versions on the U2000. Fordetails, see the iManager U2000 Operation Guide for NG WDM NE Management.

NOTE

When a board is faulty and unavailable, you cannot use the U2000 to obtain version information. In somecases, you can obtain the version information by querying the engineering document records

1.2 LaserWhen you install and maintain equipment, follow the safety precautions described below to helpprevent personal injury or equipment damage. The laser complies with IEC60825.

The safety precautions of lasers consist of two parts:

l Personal injuryl Equipment damage

Personal Injury

DANGERLaser beams from the optical ports on boards or from the fiber connectors cause eye damage.Do not look directly at the optical ports or fiber connectors during the installation andmaintenance of boards or fibers. Do not shine laser beams into the eyes of other workers.

DANGERTo prevent eye damage in the case of an optical port that is in use, use protective caps to coverthe optical interface and the fiber connector after you remove the fiber from the optical interface.



4

DANGERThe Raman amplifier board is very high. Shut down the pump laser before you insert or removefiber connectors on the Raman amplifier board to help prevent personal injury that is caused byhigh optical power.

Equipment Damage

CAUTIONUse protective caps to cover unused optical ports and fiber connectors so that they do not gatherdust.

CAUTIONWhen performing a hardware loopback test on optical ports using a fiber, add an opticalattenuator to prevent damage to the equipment because of the high power of the laser beam. Addthe attenuator at the receive optical port on a board that supports optical attenuators.

CAUTIONWhen you use the optical time domain reflectometer (OTDR), disconnect the fiber between theopposite station and the board to prevent damage to the receive optical module because of highoptical power.

CAUTIONExercise caution when you remove or insert a board that is connected with fibers.



5

CAUTIONThe optical power of the Raman amplifier board is very high. Observe the following precautionswhen using the Raman amplifier board to prevent damage to the equipment.

l Do not use fiber connectors within 0–20 km. The fibers at every joint point must be spliced.

l The single-point additional loss within 0–10 km must be smaller than 0.1 dB (G.652) or0.2 dB (G.655) and the single-point return loss must not be smaller than 40 dB.

l The single-point additional loss within 10–20 km must be smaller than 0.2 dB (G.652) or0.4 dB (G.655) and the single-point return loss must not be smaller than 40 dB.

l Fiber connections must be complete before you enable the lasers on the Raman amplifierboard. Make sure that the fiber connectors are clean. Otherwise, the fiber connectors mightbe damaged when you insert or remove the fiber connectors.

l The optical power of the LINE interface on the Raman amplifier board is very high. TheLSH/APC optical connectors must be used in the fiber that is connected to the LINEinterface.

l For the Raman amplifier board with backward pump, the strong pump light enters the fiberthrough the input end (LINE) instead of the output end (SYS). Do not add boards or non-fiber devices, such as attenuators or fiber jumpers, at the input end.

l The bent radius of the fiber that is connected to the LINE interface on the Raman amplifierboard must be larger than 30 mm to prevent the fiber from being burned.

1.3 Short CircuitExercise caution where you place metallic tools so that you do not cause a short circuit in anyequipment.

CAUTIONDo not place tools, such as screwdrivers, on the air baffle.

CAUTIONEnsure that screws do not fall off into the subrack or chassis.

1.4 ESDDuring installation and maintenance, follow antistatic procedures to prevent equipment damage:

l Always wear an ESD wrist strap during the operation.

l Check that the equipment is securely grounded.



6

CAUTIONWear a well-grounded ESD wrist strap whenever you touch equipment or boards. Make surethat the wrist strap touches your skin. Insert the ESD strap connector into the ESD socket of theequipment.

For information about how to wear an ESD wrist strap, see Figure 1-1.

Figure 1-1 Wearing an ESD wrist strap

NOTE

Insert the connector of the ESD strap into the equipment port. For details, see the Quick Installation Guide.

When you are following antistatic procedures, take the following precautions:

l Check the validity and functionality of the wrist strap. Its resistance value must be between0.75 mega ohm to 10 mega ohm. If the wrist strap validity period (usually two years) hasexpired, or if the resistance value fails to meet requirements, replace it with a wrist strapthat provides the required resistance value.

l Do not touch a board with your clothing. Clothing generates static electricity that is notprotected by the wrist strap.

l Wear an ESD wrist strap and place the board on an ESD pad when you replace boards orchips. Use ESD tweezers or extraction tools to replace chips. Do not touch chips, circuits,or pins with your bare hands.

l Keep the boards and other ESD-sensitive parts you are installing in ESD bags. Place theremoved boards and components on an ESD pad or ESD material. Do not use non-antistaticmaterials such as white foams, common plastic bags, or paper bags to pack boards, and donot let these materials touch the boards.

l Wear an ESD wrist strap when operating the ports of boards because they are also ESD-sensitive. Discharge the static electricity of cables and protective sleeves before you connectthem to the ports.



7

l Keep packing materials (such as, ESD boxes and bags) available in the equipment roomfor packing boards in the future.

ESD complies with IEC Publication 1000, EN 55022, EN 55024, IEC 61000 and GR-1089-CORE.

1.5 Working on Equipment with Power AppliedWhen you perform operations on the equipment when power is applied, ensure that you take thesafety precautions to prevent personal injury or equipment damage.

DANGERDo not install or disassemble equipment when power is applied.

DANGERDo not install or remove power cables on equipment when power is applied.

1.6 Alarm and Safety SymbolsDuring equipment installation and maintenance, observe the precautions indicated by the alarmand safety symbols to help prevent personal injury or equipment damage.

Table 1-2 describes the alarm and safety symbols on the WDM equipment.

Table 1-2 Symbols on the WDM equipment

1.7 Correct Board Inserting and RemovingRemoving an in-service board can interrupt services. Perform board hot swapping during off-peak hours.

If the board to be removed is a line board without protection and carries ASON services, optimizethe ASON services traversing the board to other paths before removing the board.

CAUTIONl Do not use excessive force when inserting a board to avoid distorting the pins on the

backplane.l Insert the board along the slide rail of each slot. To help prevent a short circuit, make sure

the components do not touch each otherl When holding a board, never touch the circuit, components, connectors, or connection slots.l For optical-layer ASON services, the new paths must be commissioned; otherwise, the

services may be interrupted. You are advised to optimize the ASON services to their presetrestoration paths.

If a board is reinserted in the backplane, it will be in the running state several minutes after itstarts.

For details about how to insert or remove a board, see "Replacing a Board" of the SupportingTasks.

NOTE

l The time interval between power-on and power-off of a piece of equipment must be more than 10seconds.

l Wait at least ten seconds between board removal and board insertion.

4.2 Replacing the Protected SCC Board in a Master SubrackThis section describes how to replace the SCC board of the master subrack when SCC 1+1protection is configured.

Prerequisitel You must be an NM user with "NE and network operator" authority or higher.

l The FTP/TFTP/SFTP server is configured and the FTP/TFTP/SFTP service is started. Formore information, see the U2000 NE Software Management.




27

l The SCC replacement board must be the same type as the SCC board being replaced.

Impact on SystemReplacing an SCC board configured with protection does not affect the existing services.

In the case of SCC 1+1 protection, replacing one of the SCC in the protection group does notinterrupt communication between the NE where the SCC board resides and the U2000 after youswitch services from one SCC board to the other SCC board.

Tools, Equipment, and MaterialsESD bag, U2000, multimeter

Background InformationBefore an SCC board is replaced with a spare board, you must set the battery jumper on the spareSCC board with reference to 4.1 Setting the Battery Jumper on the SCC.

You must clear the database on the spare SCC board before starting the replacement. You clearthe database by configuring the BIOS running mode by using four setting jumpers on the spareSCC board. The figure below shows the four jumpers for setting the BIOS running mode andthe battery jumper on an SCC board. The four jumpers for setting the BIOS running mode arearranged from high order to low order and identified as 04, 03, 02, and 01.

The setting of each jumper corresponds to a binary value, either 0 or 1. When a jumper is notcapped, the setting corresponds to binary 0. When the jumper is capped, the setting correspondsto binary 1. The settings of the four jumpers can be arranged in 16 combinations, representing0 to 15 in the decimal system. The default setting of the four jumpers is 0000.

Step 7 Inform the onsite maintenance engineer and replace the board. For details about how to removea board, see "Replacing a Board" of the Supporting Tasks.




35

Step 8 Set the four jumpers on the spare SCC board to set the BIOS running mode, and then insert theSCC board to the slot housing the original SCC board. In this manner, the database on the newSCC board is cleared.1. Set the BIOS running mode of the spare SCC board to 1111 to clear the database in the

flash memory. Figure 4-14 shows the settings of the four jumpers on the SCC board.2. Insert the spare SCC board in the slot housing the original SCC board.

NOTE

After you set the jumpers and install the new SCC board in the slot, wait 15 minutes to allow the databaseto be cleared.

Step 9 After the database of the SCC board is cleared completely, remove the board. Remove the jumpercaps which you set in Step 8. Reinsert this SCC board to the slot.

Step 10 View the indicators on the front panel of the new board. It takes approximately 90 minutes fora new board to work normally after insertion. Ensure that the STAT indicator is steady green.If the indicator is not steady green, you need to reinsert the board or select a new replacementboard. For details about the indicators, see "Indicators" in the Hardware Description.

Step 11 Optional: Follow the steps below to switch the active/standby state of the SCCs back to theoriginal state.


2. Choose Configuration > Board 1+1 Protection from the Function Tree.3. In Board 1+1 Protection, right-click SCC Board 1+1 Protection. Select Restore

Working/Protection from the shortcut menu. Click OK in the window displayed.

NOTEAfter you start the new SCC board, the system automatically synchronizes the data between the existingSCC board and the new SCC board. After data backup completes, you can perform the preceding step toinitiate active/standby switching.

Step 12 Check and set the other parameters on the U2000 to ensure that the parameter values of the newboard are the same as the original data.1. Check the software information of the new SCC against the original data.2. Synchronize the NE time with the NMS server time.3. Check the NE alarm attribute data against the original data. The data include saving mode,

reversion mode and delayed report.4. Check the alarm suppression setting data against the original data.5. Enable the NE performance monitoring.6. Check whether the switching state is correct. Perform a switching test.

NOTEFor details to set these parameters, see iManager U2000 Operator Guide for NG WDM NE Management.

Step 13 Querying the current alarms of the NE by using the U2000.

1. In the Main Topology view, choose Fault > Browse Current Alarm from the Main Menu.2. Click the Basic Setting and Alarm Source tabs in turn on the Filter dialog box to set the

filter conditions for the current alarms.3. Click OK.4. Record the current alarms of the NE.

4.3.2 Replacing the SCC Board with the Database Backed Up to aCF Card (NE Is Unreachable)

When the NE is unreachable resulting from a damage of the SCC board, restore the NE databasefrom the CF card after replacing the SCC board if there is no backup data on the NMS.

PrerequisiteYou must be an NM user with "NE and network operator" authority or higher.

The SCC replacement board must be the same type as the SCC board being replaced.




You must clear the database on the spare SCC board before replacing the replacement board.You can clear the database by setting the BIOS running mode by using four jumpers on thereplacement SCC board. The figure below shows the four jumpers for setting the BIOS runningmode and the battery jumper on an SCC board. The four jumpers for setting the BIOS runningmode are arranged from high order to low order and identified as 04, 03, 02, and 01.

The setting of each of the four jumpers corresponds to a binary value, either 0 or 1. When ajumper is not capped, the setting corresponds to binary 0. When a jumper is capped, the settingcorresponds to binary 1. The settings of the four jumpers can be arranged in 16 combinations,representing 0 to 15 in the decimal system. The default setting of the four jumpers is 0000.

Precautions

CAUTIONl If the NE where the SCC to be replaced resides is an ASON NE, the Node ID of the NE must

be set according to the original data after the SCC is replaced. Otherwise, the ASON servicecannot be restored.

l After the database of the NE is restored on the CF card, the restoration must be completedwithin two hours after you install the replacement SCC is installed. If you wait more thantwo hours to restore the database of the NE on the CF card, the data automatically saved onthe NE overwrites the original data stored on the CF card. If the original data is overwritten,the original database of the NE cannot be restored.



Procedure


NOTEThe 1X3 jumper (namely, the battery jumper) on the board is used to enable or disable the power supplyfrom the battery. Make sure that pin 1 and pin 2 of each jumper are capped. Then, cap pin 2 and pin 3 onthe jumper and use a multimeter to measure the battery voltage. If the voltage is lower than 3 V, the batteryis not working. The board must be replaced.

Step 2 Remove the SCC board to be replaced. For more information, see "Replacing a Board" of theSupporting Tasks.

Step 3 On the SCC board that has been removed, hold the CF card and pull the card out of the CF cardslot. Put the SCC into an ESD bag.

NOTE

Keep the CF card because it is required for NE data restoration.

Step 4 Set the four jumpers on the spare SCC board so as to set the BIOS running mode of the SCCboard and then insert it to the slot housing the original SCC board. In this manner, the databaseon the new SCC board is cleared.

1. Set the BIOS running mode of the spare SCC board to 1011 to clear the database in theflash memory. Figure 4-28 shows the settings of the four jumpers on the SCC board.

2. Insert the spare SCC board to the slot housing the original SCC board.

3. Wait for a few minutes until the PROG indicator is green and slowly flashes. Remove thespare SCC board and then set its BIOS running mode to 1010 to clear the system parameterarea. For the settings of the four jumpers on the SCC board, see Figure 4-29. After that,reinsert the new SCC board to the slot.

NOTE

After the four BIOS jumpers are set and you install the SCC board in the slot, the PROG indicator on theSCC board is constantly green, which indicates that the database is being cleared. Wait for a few minutesuntil the PROG indicator blinks green, which indicates that the database is cleared completely.




57


Step 6 After the new SCC board is started, connect the Web LCT to the NE. Modify the NE attributeto restore the communication between the NE and the U2000.1. Disconnect the cables from the NM_ETH1 and NM_ETH2 ports (if connected). That is,





4. Log in the Web LCT with the user name admin, and the initial password admin.






6. Click Cancel to exit the Manage Domain Search dialog box.7. Select appropriate network segment IP addresses within the Domain and click Search.

NOTE


Step 15 Restore the network connection of the NE.1. Remove the network cable which connected the NM_ETH1 port to the Web LCT.2. Connect the network cable removed.


Step 16 After the SCC board is started, remove the SCC board inserted just now. Insert the CF card thathas been removed in Step 3 into the CF card slot on the SCC board. Then, insert the SCC.

Step 17 After the SCC board is started and the communication between the NE and U2000 is normal,go to Step 14.



Step 20 Restore the initial database of the NE by using the U2000.

1. In the Main Topology view, choose Configuration > NE Configuration DataManagement from the Main Menu, and the NE Configuration Data Managementinterface is displayed.

2. In the Object Tree on the left, select an NE and click .3. In NE Configuration, select an NE or multiple NEs.4. Click Restore NE Database from CF Card. The Confirm dialog box is displayed,

indicating that the restoration of the NE database may lead to service interruption.




60

5. Click OK to start to restore the NE database.6. Click Closeafter an Operation Result dialog box is displayed.

NOTEAfter the NE databases are restored, the NE software issues the data in the CF card to only the SCC boardbut not other boards. To ensure that the configurations in the SCC board and the configurations in otherboards are consistent, you need to perform warm resets on other boards.

4.3.3 Replacing the SCC Board After Configuring SCC 1+1Protection

When replacing an SCC board, you can configure protection for the SCC board if the NE isreachable and the slot for housing the standby SCC board is not occupied by a service board.


more information, see U2000 NE Software Management.l The type of the replacement SCC board is the same of the SCC board to be replaced.

Impact on System

Replacing the SCC does not affect the existing services.

The impact caused by replacing an SCC without protection is as follows:

l For the OptiX OSN 8800 T16, the SCC is housed in IU9 by default. When IU10 is notoccupied by another board, it is available for another SCC to implement 1+1 protectionwith the SCC in IU9. In this case, replacing one of the SCC in the protection group doesnot interrupt the communication between the NE where the SCC resides and the U2000after a switching from this SCC to the other SCC is performed.


l For the OptiX OSN 8800 T64, the SCC is housed in IU74 by default. When IU85 is vacant,it is available for another SCC to implement 1+1 protection with the SCC in IU74. In thiscase, replacing one of the SCC in the protection group does not interrupt the communicationbetween the NE where the SCC resides and the U2000 after a switching from this SCC tothe other SCC is performed.

l For the OptiX OSN 6800, the SCC is housed in IU18 by default. When IU17 is not occupiedby another board, it is available for another SCC to implement 1+1 protection with the SCCin IU18. In this case, replacing one of the SCC in the protection group does not interruptthe communication between the NE where the SCC resides and the U2000 after a switchingfrom this SCC to the other SCC is performed.

l For the OptiX OSN 3800, the SCC is housed in IU9 by default. When IU8 is not occupiedby another board, it is available for another SCC to implement 1+1 protection with the SCCin IU9. In this case, replacing one of the SCC in the protection group does not interrupt the




62

communication between the NE where the SCC resides and the U2000 after a switchingfrom this SCC to the other SCC is performed.




The setting of each of the four jumpers corresponds to a binary value, either 0 or 1. When ajumper is not capped, the setting corresponds to binary 0. When the jumper is capped, the settingcorresponds to binary 1. The settings of the four jumpers can be arranged in 16 combinations,representing 0 to 15 in the decimal system. The default setting of the four jumpers is 0000.

Precautions





Procedure

Step 1 Select a spare SCC board as the replacement board. Ensure that the spare SCC board and theSCC board to be replaced have the same name and type.

NOTEThe 1X3 battery jumper on the replacement board enables or disables the power supply from the battery.Ensure that pin 1 and pin 2 of this jumper. Then, remove the cap of pin 1 and cap pin 3 on the jumper anduse a multimeter to measure the battery voltage. If the voltage is lower than 3 V, the battery is not working.The selected SCC board cannot be used as a replacment board.

Step 2 Back up the NE database to the NMS server. This records the NE database when the SCC boardis replaced for future reference.



NOTE




NOTE





Step 3 Set the jumpers on the spare SCC board by using the following methods and insert it to thespecified slot for a standby SCC board. In this manner, the database on the new SCC board iscleared.




70

NOTE

After inserting the spare SCC board to the specified slot for a standby SCC board, you need to add a correspondinglogical board on the U2000. Then, the system automatically configures 1+1 protection for the SCC.

1. Set the BIOS running mode of the spare SCC board to 1111 so as to clear the database inthe flash memory. Figure 4-36 shows the settings of the four jumpers on the SCC board.


NOTE

After the four jumpers are set and the SCC board is inserted to the slot, you must wait approximately 15minutes to allow the database to clear.


Step 5 Review the indicators of the new board. It takes 90 minutes for a board to work normally afterthe board is inserted. Ensure that the STAT indicator is steady green. If the indicator givesabnormal indication, you need to reinsert the board, or replace the board again. For details aboutindicator definitions, see "Indicators" of the Hardware Description.

Step 6 Wait for 90 minutes. After the SCC board starts, add the logical board of the SCC board on theU2000.

Step 7 Log in to the U2000 and complete the following steps to perform an active/standby switchbetween the SCC boards.


2. Choose Configuration > Board 1+1 Protection from the Function Tree.3. In Board 1+1 Protection, right-click the desired SCC Board 1+1 Protection. Select

Working/Protection Switching from the shortcut menu. Click OK in the windowdisplayed.

4. Click Query. If the Active Board is not the board to be replaced, the switching is successful.5. Query the alarms and performance events on the U2000. Check if services are normal. If

services are normal, there must be no new abnormal alarms or performances. The switchingis successful.

NOTEAfter the new SCC board is started, the system automatically backs up the data on the existing SCC boardto the new SCC board. After the data is backed up, you can perform the preceding step to initiate an active/standby switching.

If the SCC is configured with 1+1 protection, replacing the SCC does not affect the system.

If an SCC is not configured with 1+1 protection, replacing the SCC has the following effects:l The fan is automatically changed to the "High Speed" mode.l The ESC and OSC communication of the subrack where the replacement SCC resides fails.l The POWER_FAIL alarm of the subrack where the replacement SCC resides cannot be

reported.l The subrack whose ID conflicts with the ID of the subrack where the replacement SCC

resides cannot be detected.l Certain optical boards in the slave subrack housing the SCC board to be replaced go offline

and cannot be managed. However, the services on these boards are not affected.


Background InformationBefore an SCC board is replaced with a spare board, you must set the battery jumper on the spareSCC board with reference to 4.1 Setting the Battery Jumper on the SCC.

You must clear the database on the spare SCC board before starting the replacement. You clearthe database by configuring the BIOS running mode by using four setting jumpers on the spareSCC board. The figure below shows the four jumpers for setting the BIOS running mode andthe battery jumper on an SCC board. The four jumpers for setting the BIOS running mode arearranged from high order to low order and identified as 04, 03, 02, and 01.

The setting of each jumper corresponds to a binary value, either 0 or 1. When a jumper is notcapped, the setting corresponds to binary 0. When the jumper is capped, the setting correspondsto binary 1. The settings of the four jumpers can be arranged in 16 combinations, representing0 to 15 in the decimal system. The default setting of the four jumpers is 0000.

6.2.3 Replacing the SCC Board After Configuring SCC 1+1Protection

When replacing an SCC board, you can configure protection for the SCC board if the slot forhousing the standby SCC board is not occupied by a service board.


details, see U2000 NE Software Management.

Impact on SystemThe replacement does not affect the existing services.



l For the OptiX OSN 6800, the SCC is housed in IU18 by default. When IU17 is not occupiedby another board, it is available for another SCC to implement 1+1 protection with the SCCin IU18. In this case, replacing one of the SCC in the protection group does not interruptthe communication between the NE where the SCC resides and the U2000 after a switchingfrom this SCC to the other SCC is performed.

162

7.1 Under Board 1+1 ProtectionThis section describes how to replace the cross-connect board when cross-connect board 1+1protection is configured.


Impact on SystemWhen cross-connect 1+1 board protection is configured, replacing the cross-connect boardbrings no impact on the services in case of a normal switching.

During board replacement, the board software takes several minutes to be synchronized. At thispoint, the PROG indicator on the board is blinking green quickly.

Tools, Equipment, and MaterialsESD bag, U2000

Procedure

Step 1 Select a spare board. Ensure the name, version and model number of the new board are the sameas those of the original board.

NOTE

If the version is inconsistent, you need to determine if the board with different versions can be replaced.For more information regarding the replacement relation between board versions, refer to the HardwareDescription.

Step 2 Query and record the current alarms on the NE. For details, see "Querying the Current Alarms"of the Supporting Tasks. Check whether the BUS_ERR alarm has occurred to the subrack wherethe cross-connect board is located. If it has occurred, clear the alarm before the replacement.Otherwise, replacing the board causes a service interruption.

Step 3 Perform an active/standby switching on the U2000.

NOTE

For OptiX OSN 8800 T32, assume that the cross-connect board to be replaced in slot 9 is the active cross-connect board, and that the cross-connect board in slot 10 works normally and no BUS_ERR alarm isgenerated on the subrack.

For OptiX OSN 8800 T64, assume that the cross-connect board to be replaced in slot 9 (slot 10) is theactive cross-connect board, and that the cross-connect board in slot 43 (slot 44) works normally and noBUS_ERR alarm is generated on the subrack.

NOTE

For OptiX OSN 6800, assume that the XCS board to be replaced is located in slot 9 and it is the main XCSboard, and that the XCS board in slot 10 works normally and the subrack where it is located has noBUS_ERR alarm.





163

3. In Board 1+1 Protection, right-click the desired Cross-Connect Board 1+1Protection . Select Working/Protection Switching from the shortcut menu. Click OK inthe window displayed.



Step 4 Inform the onsite maintenance engineer and replace the board. For details about how to replacea board, see "Replacing a Board" of the Supporting Tasks.

NOTE

After the board is replaced, the NE software delivers the configuration of the original board automatically.

Step 5 Check the indicators of the new board. It takes four or five minutes for a new board to worknormally after insertion. Ensure that the STAT indicator is steady on green. If the indicator isnot steady on green, you need to reinsert the board or select a new replacement board. For detailsabout the indicators, see "Indicators" of the Hardware Description.

Step 6 Follow the steps below to cancel the switching.


2. Choose Configuration > Board 1+1 Protection from the Function Tree.3. In Board 1+1 Protection, right-click the desired Cross-Connect Board 1+1 Protection.

Select Working/Protection Switching from the shortcut menu. Click OK in the windowdisplayed.

Step 7 Query alarms and performances of the local NE and of the opposite NE and confirm that theoriginal alarms or performances are cleared.

----End

7.2 Under No ProtectionThis section describes how to replace the cross-connect board when no protection is configured.


Impact on SystemWhen you replace the cross-connect board without protection, that is, the only cross-connectboard (suppose it is in IU9) on an NE.

l For OptiX OSN 6800,– When IU10 is occupied by other boards, cross-connect board protection cannot be

configured. Replacement of the cross-connect board causes interruption of traditionalservices.− If the NE whose cross-connect board needs to be replaced is an intermediate NE ofelectrical-layer ASON services, optimize the electrical-layer ASON services traversingthe NE to other paths (the preset restoration paths are preferred if the preset restorationpaths of the services do not traverse the NE) before board replacement. Then, switch



164

the services back to the original paths after board replacement and verify that the servicesare running correctly.− If the NE whose cross-connect board needs to be replaced is an NE where electrical-layer ASON services are added or dropped, the services will be interrupted during boardreplacement.

– When IU10 is not occupied by other boards, it is available for another cross-connectboard to realize 1+1 protection with the cross-connect board in IU10. When the cross-connect board has 1+1 protection and when the switching is normal, replacement of thecross-connect board does not cause service interruption



Procedure


NOTE



Step 3 For OptiX OSN 6800, If IU10 is not occupied by other boards, insert another cross-connectboard in IU10. Then the system automatically configures the cross-connect board 1+1 protection.For steps to replace an cross-connect board that is configured with board 1+1 protection, see7.1 Under Board 1+1 Protection.


NOTE


Step 5 Check the indicators of the new board. It takes four or five minutes for a new board to worknormally after insertion. Ensure that the STAT indicator is steady on green. If the indicator isnot steady on green, you need to reinsert the board or select a new replacement board. For detailsabout the indicators, see "Indicators" of the Hardware Description.

Impact on System

When client 1+1 protection is provided, replacing a tributary board generally brings no serviceinterruption. Before replacing a line board, check if the service from the line to a tributary boardis provided with client 1+1 protection on the tributary board. If protection is provided for theservice, replacing the line board generally brings no service interruption. If no protection isprovided for the service, replacing the line board brings a service interruption.

Precaution

CAUTIONWhen you connect a fiber to the input optical port of a line board or tributary board, looselyconnect the fiber to prevent the input optical power from crossing the overload point; otherwise,the receiver optical module is burnt and damaged.The overload optical power point of an APD receiver laser is only -9 dBm, which must be takenwith special caution to prevent the optical module from being burnt or damaged.

Procedurel Procedure for Replacing a Line Board.

1. Select a spare board. The name, version, model number, operating wavelength, opticalmodule and software version of the new board must be the same as those of the originalboard.

NOTE

If the version is inconsistent, you need to check whether the board with different versions canbe replaced. For details about the replacement relationship between board versions, see theHardware Description.

Query the optical module information. For details, see "Querying Optical Module Information"of the Supporting Tasks.

2. Query and record the current alarms on the NE. For details, see "Querying the CurrentAlarms" of the Supporting Tasks.

NOTE

When a line or tributary board needs to be replaced for the upgrade purpose, perform this step tocheck whether abnormal alarms are generated on the NE where the board is located and thedownstream NE. If abnormal alarms are generated, remove these alarms before you replace theboard.

3. Test the input optical power. Prevent the input optical power from crossing theoverload point; otherwise, the receiver optical module is burnt and damaged. For theprocedure, see the "Testing Optical Power by Using an Optical Power Meter" inSupporting Tasks.

9.7 Under No ProtectionThis section describes how to replace a line board or a tributary board when no protection isconfigured.


Impact on System

Replacing an unprotected tributary or line board brings interruption of traditional services.

If the board to be replaced is a line board without protection and carries electrical-layer ASONservices, optimize the electrical-layer ASON services traversing the board to other line boards(the preset restoration paths of the services are preferred if they do not traverse the line board tobe replaced) before board replacement. Then, switch the services back to the original paths afterboard replacement. If the board to be replaced is a tributary board, the services will be interruptedduring board replacement.

NOTEWhen you replace the NPO2/NPO2E board and the ENQ2 board at the same time, it is recommended toreplace the NPO2/NPO2E board first.

Precautions

CAUTIONWhen you connect a fiber to the input optical port of an NPO2 or NPO2E board, loosely connectthe fiber to prevent the input optical power from crossing the overload point; otherwise, thereceiver optical module is burnt and damaged.

Procedure (Replacing a PID Board and a PQ2 Sub-board)1. Select a spare board. Ensure the name, version, and software version of the new board are

the same as those of the original board. If the version is inconsistent, you need to determineif the board with different versions can be replaced. For more information on board versions,refer to the Hardware Description.

2. Review and record the current alarms on the NE. For more information, refer to "Queryingthe Current Alarms" of the Supporting Tasks.

NOTE

To replace a board in an upgrade, perform this operation to determine if abnormal alarms are generatedon the NE where the board to be replaced resides and the downstream NE. If there are abnormal alarms,you need to handle these alarms before replacing the board.

3. Test the input optical power. Prevent the input optical power from crossing the overloadpoint; otherwise, the receiver optical module is burnt and damaged. For the procedure, referto the Testing Optical Power by Using an Optical Power Meter in Supporting Tasks.

34 Replacing SDI Components

This section describes how to replace a component (such as fan module, power supply module,and control board) on the digital video O/E conversion chassis and how to replace the SDI-specific SFP module on the TOM board.

Prerequisite

None

Impact on Systeml Replacing a fan module has no impact on the existing services.

NOTE

A fan module must be replaced in time after it is damaged. This prevents the SDI from being damageddue to excessively high working temperature.

l Replacing a power supply module has no impact on the existing services if there are activeand standby power supply modules. Otherwise, the digital video O/E conversion chassis ispowered off during the replacement and thus the existing services are interrupted.

l Replacing a control board has no impact on the existing services if there are active andstandby control boards.

NOTE

The preceding components in the digital video O/E conversion chassis are hot-swappable.

l Replacing an SFP module interrupts the existing services.

NOTE

This SFP module is dedicated for the SDI.


ESD bag, flathead screwdriver


The SDI consists of an O/E conversion chassis and the SFP module on the TOM board. The SFPmodule on the TOM board is specific for connecting to the SDI.
