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

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

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.

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).

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.

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'

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

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.:

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 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

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.

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.

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

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).

Configurator-BasedIOM ReplacementSoftware Release
Version 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 IOM to stay in that state.
Step 1: If you do not have an Operator Interface Station
connected to the active card, connect the OIS computer/converter to
a free serial port of the active card group. If there are no free
serial ports, you may have to use a LSAM (see on page 1-105).
Step 2: Set the modules access level to Engineer, as described
in Password Structure and Settings in Section (4-2.1) of
publication T4MN_02b.
Step 3: Select the FTOS parameter set from the Configurator Main
Screen.
Step 4: Select the TOPOLOGY parameter group. The parameters
located within this group will be displayed. Note the value of the
Active IOM Slot (_sys_active) parameter.
Step 5: Double click the Force Active Slot No.:
(_sys_force_active) parameter.
Step 6: Set the Force Active Slot No.: (_sys_force_active)
parameter to the same value as the Active IOM 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 7: Click on the OK box. The selection window will close and
forced-active mode of operation will be enabled.
2. Verify the replacement IOM.
Step 8: Select a replacement IOM from your spares inventory that
has been designated as a direct replacement for the IOM being

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.
