    Chapter 1: On-line Module Replacement

    This section provides instructions for replacement of individual Series 4 modules. It discusses the following topics:n Replacement of OIMs and OICMs ( on page 1-2),n Replacement of Simplex AFMs (page 1-4), andn Replacement of Fault Tolerant AFMs (page 1-8).

    Warning! Do not attempt to perform any maintenance on a Series 4 product until the process has been placed in a safe state. When performing maintenance on a fault tolerant AFM, verify that a correctly operating module is actively in control of the process. When performing maintenance on a simplex AFM, verify that the process is either shutdown or under the control of another device.

    Caution: Handling Series 4 AFM module assemblies without adequate static discharge precautions can result in damage to the module. When installing modules, always wear a wrist strap and work on a properly grounded, conductive worksurface.

    Caution: Verify that the hardware configurations (jumpers, daughter card type, etc.) and software configurations (software release version, bundle, parameters, etc.) are identical to those of the card you are replacing. Set the appropriate parameters to allow the replacement card to recognize the chassis and its running peers.

    It is recommended that the person performing the card replacement procedure follow the above guidelines and be familiar with the following aspects of Series 4:n Operation Series 4 Configurator and related OS.n Series 4 serial communication protocols and hardwaren Series 4 AFM and daughter card jumper settingsn Series 4 alarms and alarm handling

    UpdatedReplacement of

    FT AFM'sSoftwareRelease

    Versions 4through 5.02

    The following is a modification of the procedure for replacement of Fault Tolerant AFM's (Section 4-1 of UM 4001 (1.2) June 1996), and is intended as an example of a typical procedure that should be followed for replacement of modules using Software Versions 4 through 5.02. The reason for this modification is that it is possible for the AFM to incorrectly determine its peer communication and the FTOS will initialize as a simplex module and take control of the outputs. This is true even if the currently active card was forced active. It is possible to disturb or shutdown a running process/unit if this were to occur. Problems occur if the card is not inserted improperly, or has damaged peer comm drivers, and does not recognize the chassis or its running peers. n You will need a spare slot or chassis of the same type as

    the one your active card is in to view and modify parameters in the replacement card.

    n You will need a Series 4 Configurator to modify parameters in the active and replacement card.

    n You will need a free serial port for the Series 4 Configurator. If Serial ports are not available then an optional LSAM (see on page 1-105) may be used for this procedure.

    n You will need to know what Software Release Versions you are using.

    n You will need to know what type of chassis you are using.

    The following topics are discussed:n Software Release Version History (page 1-9),n Replacement of Fault Tolerant MPMs ( on page 1-14),n Replacement of Fault Tolerant IOMs (page 1-50), andn Replacement of Fault Tolerant EIOMs (page 1-87).

    Warning! DO NOT SKIP STEPS!

    Caution: The actual steps that need to be performed differ based on the type of operator interface device and what Software Release Versions are used in your system.

    Replacement ofFault Tolerant

    MPMs

    The process of replacing a fault tolerant MPM can be logically broken down into five major parts (based on the assumption that a switchover has occurred and a properly operating MPM has control of the process):1. Force the presently Active MPM to stay in that state.

    As outlined in the Warning at the beginning of this section, it is imperative that the process be placed under the control of a correctly operating device before maintenance is performed. When replacing a module in a fault-tolerant set, the Active module needs to be forced to remain in the Active state until all maintenance has been completed. This will prevent a premature switchback to the module that is being replaced provided the replacement card was verified, it was installed correctly and there were no hardware problems.

    Note: If you are removing an MPM from service that is still in the Active state, be certain that all switchable errors have been cleared from the subordinate backup IOMs before removing the Active MPM from the system. If any switchable errors remain in the backup IOMs, the Active IOMs will not switch over to the Backup modules when the Active MPM is removed. (See Chapter 3 in publication UM4002 Series 4 Application Function Module Concepts for more information.)The status LEDs on the front bezel of each backup IOM can be used to verify that no switchable errors exist. If the IOMs Ind 1 LED is on continuously and its Ind 2 LED is flashing, no errors of any type exist. If the Ind 1 LED is flashing and the Ind 2 LED is off continuously, only warning errors exist and a switchover to that IOM can still occur.

    2. Verify the replacement MPM.Verify that the hardware configurations (jumpers, daughter card type, etc.) and software configurations are identical to the card you are replacing. Set the appropriate parameters to allow the replacement card to recognize the chassis and its running peers.

    3. Physically replace the MPM.The failed MPM is replaced with an MPM that has been designated as a direct replacement for the MPM being removed from service.

  • On-line Module Replacement 1-15

    Section taken from: T4MN_02b (2.3) - Series 4 MaintenanceTraining Manual

    4. Verify and/or Confirm that the replacement module is functioning correctly.The status indicator LEDs and the alarm buffer on the replacement MPM must be checked carefully to verify that the module is functioning correctly. In software release versions 5.01, user confirmation is required for some MPM's. In software release versions 4, 5.00 and 5.02 user confirmation is NOT required for MPM's.

    5. Release the module set from the forced-active mode of operation.In order to return the faulty tolerant module set to a state where it can switchover if a failure occurs at some point in the future, the module set must be released from the forced-active mode of operation. If this is not done, the MPM that is forced active will stay in the Active state even if it develops a failure.

    The actual steps that need to be performed differ based on the type of operator interface device used in your system. Instructions are given for Configurator-based systems.The following topics are discussed:n Replacement of FT MPMs SRV 4.00 ( on page 1-16),n Replacement of FT MPMs SRV 5.00 ( on page 1-23),n Replacement of FT MPMs SRV 5.01 (page 1-31), andn Replacement of FT MPMs SRV 5.02 (page 1-40).

    Configurator-BasedMPM Replacement

    Software ReleaseVersion 4.00

    The following procedure should be followed when replacing faulty modules in a fault-tolerant module set that uses Configurator as the operator interface device and Software Release Version 4.00:

    1. Force the presently Active MPM to stay in that state

    Step 1: If there is an LOIM, loosen the two retaining screws located on the front of the OIM until they are disengaged from the front bezel of the module installed in slot 3. (Figure 1-1 on page 1-2 illustrates the position of the two OIM retaining screws.) Swing the OIM out of the way (to the left).

    Step 2: If you do not have an Operator Interface Station connected to the active card, connect the OIS computer/converter to the free serial ports of the active and fatal card slots. If there are no free serial ports, you may have to use a LSAM (see LSAM instructions on page 1-105).

    Step 3: Using Configurator, set the modules access level to Engineer, as described in Password Structure and Settings in Section (4-2.1) of publication T4MN_02b.

    Step 4: Select the FTOS parameter sets from the Configurator Main Screen.

    Step 5: Select the TOPOLOGY parameter group. The parameters located within this group will be displayed. Note the value of the Active MPM Slot (_sys_active) parameter.

    Step 6: Double click the Force Active Slot No.: (_sys_force_active) parameter.

    Step 7: Set the Force Active Slot No.: (_sys_force_active) parameter to the same value as the Active MPM Slot (_sys_active) parameter. (Use the mouse to enter the slot value using the selection window.) This will force the currently Active module to stay in the Active mode.

    Step 8: Click on the OK box. The selection window will close and forced-active mode of operation will be enabled.

    Section taken from: T4MN_02b (2.3) - Series 4 MaintenanceTraining Manual

    2. Verify the replacement MPM

    Step 9: Select a replacement MPM from your spares inventory that has been designated as a direct replacement for the MPM being removed from service.

    Step 10: If there is any doubt about the replacement MPM, the following checks may be used to determine if it is a direct replacement for the module otherwise proceed to part 3, "Physically replace the MPM" on page 1-19.

    Step 11: First, gather the comparative information from the Active card. Using Configurator, view the parameter Peer Links RVRS (_sys_reverse_peer) in the TOPOLOGY group which you should currently be viewing. Write down the value of this parameter.

    Step 12: Select the group VERSIONS. The parameters located within this group will be displayed.

    Step 13: View the parameters in Database Versions (_sys_database_versions). Write down the hexadecimal numbers in the four rows for each parameter.

    Step 14: Return to the VERSIONS window.

    OS/2 Configurator - Select Exit.Win95 Configurator - Click on the in the upper left of the parameter window.

    Step 15: Obtain access to a powered spare chassis that is identical to the chassis the active card is in. Ensure that no other AFM's installed.

    Step 16: You will need a direct connection from an OIS computer/converter to the serial port A or serial port B of the first MPM slot of the spare chassis. Do not use a daisy chained serial port cable.

    Step 17: Insert your replacement card in the first slot of the MPM group of the spare chassis.

    Step 18: Using Configurator, access the FTOS of the replacement card in the spare group/chassis from the Main Screen.

    Step 19: Select the group TOPOLOGY. The parameters located within this group will be displayed.

    Step 20: Double click the parameter Force ACTIVE Slot At Power Up (_sys_force_active_startup). This parameter must be set to the slot number of the currently active card in the group you are replacing the MPM in. The replacement card would then know that the active state is forced in another card and would not become active even if it is inserted improperly, or has damaged peer comm drivers, and does not recognize the chassis and its running peers.

    Step 21: Enter a value of the active cards slot number, or use the mouse to enter the value using the keypad window.

    Step 22: Click on the OK box. The keypad window will close and forced-active at start-up mode of operation will be enabled so that the value you entered is the slot number of the active card.

    Step 23: View the parameter Peer Links RVRS (_sys_reverse_peer). Compare this value with that of the active card. If this value is not the same then you must change it to be exactly the same as the active card using the following steps:

    n Double click on the parameter Peer Links RVRS (_sys_reverse_peer).

    n Click on the correct value (off or on).Step 24: Select the group VERSIONS. The parameters

    located within this group will be displayed.

    Step 25: View the parameters in Database Versions (_sys_database_versions). Note the hexadecimal numbers in the four rows. Compare these hexadecimal version numbers with that of the active card. If these values are not the same you do not have the correct replacement card. Find the correct replacement card and begin this procedure again.

    3. Physically replace the MPM

    Step 27: Loosen the two retaining screws located on the front of the MPM until they are disengaged from the chassis. (Figure 1-1 on page 1-2 illustrates the position of the two MPM retaining screws.)

    Step 28: Grasp the top of the MPMs front bezel and pull the bezel toward you. The bezel will swing down (pivot at the bottom) until the module separates from the backplane connector. Once the module is freed from the backplane connector, return the bezel to an upright position and pull evenly on the top and bottom. Continue sliding the MPM towards you and slightly left to remove it from the chassis.

    Step 29: Obtain the replacement MPM and visually verify that the hardware configurations (jumper settings, daughter card type, etc.) are identical to the card you are replacing.

    Step 30: Guide the replacement MPM into the same slot of the chassis until it is firmly seated into the backplane connector in one single motion.

    Note: When the replacement module has been installed, it will power up in the learning mode. The Ind 1 status LED is off while the module is in this mode. The database values from the Active controller are then transferred into the replacement module. When the transfer is complete the module will progress to the Ready or Waiting state, as appropriate, and the Ind 1 status LED will go to the appropriate state. Do not remove the active module or attempt a switchover until the transfer of data is complete.

    Step 31: Install the two retaining screws located on the front of the MPM.

    4. Verify and/or Confirm that the replacement MPM is functioning correctly

    Step 32: Verify that the module is functioning correctly by comparing the state of the status LEDs on the front bezel to those listed in Alarm and Status Functions Using the Card Status LEDs (5-5.2) on page 5-56 of publication T4MN_02b.

    Step 33: If the card you have inserted is fatal, you may want to re-load the application software and begin this procedure again. If the fatal error continues, you may have a hardware problem.

    Step 34: If the card that was forced active goes fatal upon insertion of the replacement card then you did not follow the previous steps correctly.

    Step 35: Informally compare the operation of the newly inserted card with its active peer from both operating system and application points of view and make a conscious decision about a readiness of the new card to become active. Think about the consequences of releasing the force on the active card.

    Step 36: You might want to use the compare function in Configurator to verify that the parameter sets of a saved image of the active card and replacement card are accurate.

    Note: If you are comparing two cards in a group, please note that there may be some expected discrepancies such as calibration parameters, I/O values, OS time indicators, etc.

    Step 39: View the parameter Logical Plex (_sys_logical_plex).This parameter indicates the sum of the recognized individual card values._sys_logical_plex - Displays the logical fault tolerant configuration of the module based on peer communications with non-fatal controllers. This configuration is represented by a value which is a bit pattern with the '1' bit representing slot 3, the '2' bit representing slot 2, and the '4' bit representing slot 1. Therefore, if the value of _sys_logical_plex is '6', it means that you are in a duplex state with controllers in slots 1 and 2 (4 + 2). If the value is '7' (4 + 2 + 1) you are running triplex.If a controller is in the 'fatal' state following a severe error, it will not be recognized by its peers. i.e. We have a triplex group of MPM's where the MPM in slot 1 has gone fatal and slot 2 is now active. Looking at _sys_logical_plex on slot 2 will show '3' (duplex slots 2 and 3).Also, if a controller is in the learning state, following a reset, it will not be recognized by its peers.This parameter is represented by an array of three rows. Only row one is used which corresponds to the MPM.See the following list for the acceptable configurations.

    Note: When the replacement module has been installed, it will power up in the learning mode. The Ind 1 status LED is off while the module is in this mode. The database values from the Active controller are then transferred into the replacement module. When the transfer is complete the module will progress to the Ready or Waiting state, as appropriate, and the Ind 1 status LED will go to the appropriate state.

    Step 31: Install the two retaining screws located on the front of the MPM.

    4. Verify and/or Confirm that the replacement MPM is functioning correctly.

    The spare cards will have to be properly pre-configured for a chassis type: the parameter Users Chassis (_sys_user_chassis) will have to be set to an appropriate type or at least to AUTO before the cards are inserted into a main chassis.

    Note: In software release version 5.01, the replacement card will go to a switch 3 after the learning mode is completed. This is because the software has been updated so that the user will be required to informally compare an operation of the newly inserted card with its active peer from both operating system and application points of view and make a conscious decision about a readiness of the new card to become active. This will prevent a controlled process to be affected by the card insertion because of an incomplete initialization of application, operating mode specific software deficiencies, etc.

    Caution: Recognition of an invalid chassis ID will result in a fatal error upon leaving the learning state.

    A fatal error 'INVALID CHASSIS' will protect an active card from being affected by an incorrectly inserted or improperly pre-configured card.This pre-configuration should have been completed in step Step 23:. Please refer to this step for additional information.

    Step 39: Select the group TOPOLOGY. The parameters located within this group will be displayed.

    Step 40: View the parameter Chassis Type (_sys_my_chassis). Compare this value with that of the active card. If this value is not the same or displays INVALID then you must re-move the card and re-insert it. Go to step Step 27:.

    Step 41: View the parameter Logical Plex (_sys_logical_plex).This parameter indicates the sum of the recognized individual card values._sys_logical_plex - Displays the logical fault tolerant configuration of the module based on peer communications with non-fatal controllers. This configuration is represented by a value which is a bit pattern with the '1' bit representing slot 3, the '2' bit representing slot 2, and the '4' bit representing slot 1. Therefore, if the value of _sys_logical_plex is '6', it means that you are in a duplex state with controllers in slots 1 and 2 (4 + 2). If the value is '7' (4 + 2 + 1) you are running triplex.If a controller is in the 'fatal' state following a severe error, it will not be recognized by its peers. i.e. We have a triplex group of MPM's where the MPM in slot 1 has gone fatal and slot 2 is now active. Looking at _sys_logical_plex on slot 2 will show '3' (duplex slots 2 and 3).Also, if a controller is in the learning state, following a reset, it will not be recognized by its peers.This parameter is represented by an array of three rows. Only row one is used which corresponds to the MPM.See the following list for the acceptable configurations.

    Configurator-BasedMPM Replacement

    Software ReleaseVersion 5.02

    The following procedure should be followed when replacing faulty modules in a fault-tolerant module set that uses Configurator as the operator interface device and Software Release Version 5.02:

    1. Force the presently Active MPM to stay in that state.

    Step 1: If there is an LOIM, loosen the two retaining screws located on the front of the OIM until they are disengaged from the front bezel of the module installed in slot 3. (Figure 1-1 on page 1-2 illustrates the position of the two OIM retaining screws.) Swing the OIM out of the way (to the left).

    Step 2: If you do not have an Operator Interface Station connected to the active card, connect the OIS computer/converter to the free serial ports of the active and fatal card slots. If there are no free serial ports, you may have to use a LSAM (see LSAM instructions on page 1-105).

    Step 3: Set the modules access level to Engineer, as described in Password Structure and Settings in Section (4-2.1) of publication T4MN_02b.

    Step 4: Select the FTOS parameter set from the Configurator Main Screen.

    Step 5: Select the TOPOLOGY parameter group. The parameters located within this group will be displayed. Note the value of the Active MPM Slot (_sys_active) parameter.

    Step 6: Double click the Force Active Slot No.: (_sys_force_active) parameter.

    Step 7: Set the Force Active Slot No.: (_sys_force_active) parameter to the same value as the Active MPM Slot (_sys_active) parameter. (Use the mouse to enter the slot value using the selection window.) This will force the currently Active module to stay in the Active mode.

    Step 8: Click on the OK box. The selection window will close and forced-active mode of operation will be enabled.

  • On-line Module Replacement 1-41

    Section taken from: T4MN_02b (2.3) - Series 4 MaintenanceTraining Manual

    2. Verify the replacement MPM.

    Step 9: Select a replacement MPM from your spares inventory that has been designated as a direct replacement for the MPM being removed from service.

    Step 10: If there is any doubt about the replacement MPM, the following checks may be used to determine if it is a direct replacement for the module otherwise proceed to part 3, "Physically replace the MPM" on page 1-43.

    Step 11: First, gather the comparative information from the Active card. Using Configurator, view the parameter Chassis Type (_sys_my_chassis) in the TOPOLOGY group which you should currently be viewing. Write down the value of this parameter.

    Step 12: Select the group VERSIONS. The parameters located within this group will be displayed.

    Step 13: View the parameters in Database Versions (_sys_database_versions). Write down the hexadecimal numbers in the four rows for each parameter.

    Step 14: Return to the VERSIONS window.

    OS/2 Configurator - Select Exit.Win95 Configurator - Click on the in the upper left of the parameter window.

    Step 15: Obtain access to a powered spare chassis that is identical to the chassis the active card is in. Ensure that no other AFM's installed.

    Step 16: You will need a direct connection from an OIS computer/converter to the serial port A or serial port B of the first MPM slot of the spare chassis. Do not use a daisy chained serial port cable.

    Step 17: Insert your replacement card in the first slot of the MPM group of the spare chassis.

    Step 18: Using Configurator, access the FTOS of the replacement card in the spare group/chassis from the Main Screen.

  • 1-42 On-line Module Replacement

    May 10, 1999

    Step 19: Select the group TOPOLOGY. The parameters located within this group will be displayed.

    Step 20: Double click the parameter Force ACTIVE Slot At Power Up (_sys_force_active_startup). This parameter must be set to the slot number of the currently active card in the group you are replacing the MPM in. The replacement card would then know that the active state is forced in another card and would not become active even if it is inserted improperly, or has damaged peer comm drivers, and does not recognize the chassis and its running peers.

    Step 21: Enter a value of the active cards slot number, or use the mouse to enter the value using the keypad window.

    Step 22: Click on the OK box. The keypad window will close and forced-active at start-up mode of operation will be enabled so that the value you entered is the slot number of the active card.

    Step 23: View the parameter Users Chassis (_sys_user_chassis). Compare this value with that of the active card Chassis Type (_sys_my_chassis). If this value is not the same then you must change it to be exactly the same as the active card using the following procedure:n Double Click the parameter Users Chassis

    (_sys_user_chassis).n Select the chassis type that is the same as the

    active card (Use the mouse to select the value using the selection window.)

    n Click on the OK box. The selection window will close.

    Step 24: Select the group VERSIONS. The parameters located within this group will be displayed.

  • On-line Module Replacement 1-43

    Section taken from: T4MN_02b (2.3) - Series 4 MaintenanceTraining Manual

    Step 25: View the parameters in Database Versions (_sys_database_versions).Note the hexadecimal numbers in the four rows. Compare these hexadecimal version numbers with that of the active card. If these values are not the same you do not have the correct replacement card. Find the correct replacement card and begin this procedure again.

    Step 26: Return to the VERSIONS window.

    OS/2 Configurator - Select Exit.Win95 Configurator - Click on the in the upper left of the parameter window.

    3. Physically replace the MPM.

    Step 27: Loosen the two retaining screws located on the front of the MPM until they are disengaged from the chassis. (Figure 1-1 on page 1-2 illustrates the position of the two MPM retaining screws.)

    Step 28: Grasp the top of the MPMs front bezel and pull the bezel toward you. The bezel will swing down (pivot at the bottom) until the module separates from the backplane connector. Once the module is freed from the backplane connector, return the bezel to an upright position and pull evenly on the top and bottom. Continue sliding the MPM towards you and slightly left to remove it from the chassis.

    Step 29: Obtain the replacement MPM and visually verify that the hardware configurations (jumper settings, daughter card type, etc.) are identical to the card you are replacing.

    Step 30: Guide the replacement MPM into the same slot of the chassis until it is firmly seated into the backplane connector in one single motion.

    Note: When the replacement module has been installed, it will power up in the learning mode. The Ind 1 status LED is off while the module is in this mode. The database values from the Active controller are then transferred into the replacement module. When the transfer is complete the module will progress to the Ready or Waiting state, as appropriate, and the Ind 1 status LED will go to the appropriate state. Do not remove the active module or attempt a switchover until the transfer of data is complete.

    Step 31: Install the two retaining screws located on the front of the MPM.

    4. Verify and/or Confirm that the replacement MPM is functioning correctly.

    The spare cards will have to be properly pre-configured for a chassis type: the parameter Users Chassis (_sys_user_chassis) will have to be set to an appropriate type or at least to AUTO before the cards are inserted into a main chassis.

    Note: In software release version 5.02, the replacement MPM card will not require any user confirmation.

    Caution: Recognition of an invalid chassis ID will result in a fatal error upon leaving the learning state.

    A fatal error 'INVALID CHASSIS' will protect an active card from being affected by an incorrectly inserted or improperly pre-configured card.This pre-configuration should have been completed in step Step 23:. Please refer to this step for additional information. Step 32: If the card is fatal, you will need to remove and

    re-insert the card. Go to step Step 27:. If the card you have inserted is fatal after re-insertion, you may want to re-load the application software and begin this procedure again. If the fatal error continues, you may have a hardware problem.

  • On-line Module Replacement 1-45

    Section taken from: T4MN_02b (2.3) - Series 4 MaintenanceTraining Manual

    Step 33: Verify that the module is functioning correctly by comparing the state of the status LEDs on the front bezel to those listed in Alarm and Status Functions Using the Card Status LEDs (5-5.2) on page 5-56 of publication T4MN_02b.

    Step 34: If the card you have inserted is fatal, you may want to re-load the application software and begin this procedure again. If the fatal error continues, you may have a hardware problem.

    Step 35: If the card that was forced active goes fatal upon insertion of the replacement card then you did not follow the previous steps correctly.

    Step 36: Informally compare the operation of the newly inserted card with its active peer from both operating system and application points of view and make a conscious decision about a readiness of the new card to become active. Think about the consequences of releasing the force on the active card.

    Step 37: You might want to use the compare function in Configurator to verify that the parameter sets of a saved image of the active card and replacement card are accurate.

    Note: If you are comparing two cards in a group, please note that there may be some expected discrepancies such as calibration parameters, I/O values, OS time indicators, etc.

    Step 38: Using Configurator, select to communicate with the slot of the replacement card.

    Replacement ofFault Tolerant IOMs

    The process of replacing a fault tolerant IOM can be logically broken down into five major parts (based on the assumption that a switchover has occurred and a properly operating IOM has control of the process):1. Force the presently Active IOM to stay in that state.

    As outlined in the Warning at the beginning of this section, it is imperative that the process be placed under the control of a correctly operating device before maintenance is performed. When replacing a module in a fault-tolerant set, the Active module needs to be forced to remain in the Active state until all maintenance has been completed. This will prevent a premature switchback to the module that is being replaced provided the replacement card was verified, it was installed correctly and there were no hardware problems.

    2. Verify the replacement IOM. Verify that the hardware configurations (jumpers, daughter card type, etc.) and software configurations are identical to the card you are replacing. Set the appropriate parameters to allow the replacement card to recognize the chassis and its running peers.

    3. Physically replace the IOM.The failed IOM is replaced with an IOM that has been designated as a direct replacement for the IOM being removed from service.

    Caution: If an IOM which is being replaced has associated EIOMs, these EIOMs will have to be removed and re-seated immediately before the replacement IOM is inserted.

    Caution: If an IOM has a Logic Control Sequencer Application (GTLC bundle), the Ladder Logic program must be running and set for automatic run upon power-up.

    4. Verify and/or Confirm that the replacement IOM is functioning correctly.The status indicator LEDs and the alarm buffer on the replacement IOM must be checked carefully to verify that the module is functioning correctly. In Software Release Versions 5.01 and higher, user confirmation is required.

  • On-line Module Replacement 1-51

    Section taken from: T4MN_02b (2.3) - Series 4 MaintenanceTraining Manual

    5. Release the module set from the forced-active mode of operation.In order to return the faulty tolerant module set to a state where it can switchover if a failure occurs at some point in the future, the module set must be released from the forced-active mode of operation. If this is not done, the IOM that is forced active will stay in the Active state even if it develops a failure.

    The actual steps that need to be performed differ based on the type of operator interface device used in your system. Instructions are given for Configurator-based systems.The following topics are discussed:n Replacement of FT IOMs SRV 4.00 ( on page 1-52),n Replacement of FT IOMs SRV 5.00 ( on page 1-62), andn Replacement of FT IOMs SRV 5.01/5.02 (page 1-72).

    Step 18: If possible obtain access to a powered spare chassis that is identical to the chassis the active card is in. Ensure that no other AFM's installed.

    ORUtilize a spare group in a chassis which has had the Mux-link disabled from the MPM and no other external backplane connections. The Mux-link is what is used to send the MCC packet (Communication between the MPM and IOM groups). You can verify the functioning links by observing the flashing "link" LED's on the front of the MPM. Count how many groups are in your chassis from left to right and the active Mux-links should be flashing on the MPM. See the table below for the link #'s.

    Table 1-1 MPM Mux Links

    For example, in a triplex Rev B chassis there are four groups. If only Links 1-3 are flashing on the MPM, there are no AFM's in the fourth group, and there are no external connections to group four, then this fourth group may be used for the verification procedure.
