1.3 Fault Clearance Principle

The high system functionality of the Siemens Base Station System is achieved bymeans of system-integrated routine tests. These routine tests continually check the cor-rect functioning of the base station subsystems including the BTSEs.

The fault clearance procedures in this manual are based on these routine tests. In mostcases, the results of these routine tests are sufficient to localize the fault and clear it im-mediately at the BTSE.

The modular design of the BTSE allows you to clear a large percentage of faults in thesystem by replacing a defective module.

Sometimes, however, it may happen that faults do not result from defective modules,but from interface problems in general (for example interrupted cables). In this case,special trouble shooting procedures for interfaces are provided.

This maintenance concept guarantees a simple and fast fault clearance and leads tohigh operational efficiency.

Fault Clearance Guidelines

(The numbering refers to the above diagram.)

1. The system integrated routine test detects a fault.

2. A fault message is displayed at the Radio Commander.

3. The fault and test management at the Operation and Maintenance Center(OMC) must verify whether a local fault clearance at the BTSE is required (see Ra-dio Commander documentation).

4. Interpret the fault message and go to the fault clearance procedure of the suspectedmodule or interface in chapter 3 "Fault Clearance Procedures for Modules and Inter-faces" (module/interface names as well as LMT terms (MOs) are listed in alphabet-ical order if they appear in the fault message).Localize the fault and clear it according to the corresponding procedure.

5. As described in the corresponding procedure, verify whether the fault clearance wassuccessful:

– Was the outcome of the hardware test “pass”?

– Are there any relevant active alarms?

– Do the LEDs signal normal operation?

6. If the fault should still exist and the replaced module was not the fault cause, checkwhether there is another probable cause.

7. If there is another probable cause, reinsert the recently replaced original module andgo to the corresponding fault clearance procedure for the next suspected module orinterface.

8. It should be possible to clear most faults that may occur in the BTSE by followingthe fault clearance procedures described in this manual. However, if the fault shouldstill exist after considering all probable causes, contact the Technical AssistanceCenter (TAC). Here you will obtain help from specially trained troubleshooting ex-perts.

9. End of fault clearance. Pack and tag all faulty modules for transport to a repair depot.Write a fault report in which the following information is given in detail:

– name and code of the site

– BSS area, cabinet and slot number

– name, code and serial number of the module

– description of the system response

– description of the fault

– name and phone number of the originator

iFor the local fault clearance at the BTSE:Make sure that all spare parts that might be required to clear the fault are availableat the site. Note that sometimes more than one module may be suspected of beingdefective. This is particularly important if the failure is located in the TX/RX path(see PROC: TX/RX Path (e.g. VSWR)).For general module replacement instructions see also 1.5 "Module ReplacementInstructions".

1.5 Module Replacement Instructions

1.5.1 ESD Precautions

Fig. 1.4 ESD Symbol

Many system modules are equipped with electrostatically sensitive components(marked by an ESD symbol). Therefore, ESD precautions must be taken when removingand inserting modules.

During module replacement, personnel must wear a conductive wrist strap to dischargeelectrostatic charging. Before modules, lines or components are touched, this wrist strapmust be connected to the ground potential of the rack by means of a flexible lead inte-grating a 1 MΩ resistor. Note that the conducting parts of the split pin or the clampshould not be touched when inserting/connecting (so as to avoid bypassing the 1 MΩresistor).

1.5.2 Avoiding the Loss of Calls

If you lock or replace modules in the TX/RX path of the BTSE, calls may be lost. To avoidthe loss of calls, perform the following procedure before you lock or replace a module inthe TX/RX path.

1. Find out the corresponding TRX:To find out which TRX is related to the module, perform the following LMT command:BSSBE Btsep Br<no>:<NE id>BSS-EQUIPMENTBTSEPBTSEP<no>RACKRACK<no><Module><Module><no>GET <Module>NAME=RACK:<no>/<Module>:<no>REQATTL=RELFUNKOBJ

Get <Module>:Name=BTSE:<no>/<Module>:<no>,REQATTL=RELFUNCOBJIn the system response, the corresponding TRX is listed as related Functional Ob-ject: relatedFuncObjects FMO = BTS:<no>/TRX:<no> .

iThe following procedure is only relevant if the BTSE is in phase 3. In phase 1 or 2, theBTSE cannot establish calls.

A30808-X3247-M281-1-7620 15


MMN:BTSE BS-41

2. Check the state of the corresponding TRX (only possible in phase 3):To check the state of the corresponding TRX, perform the following LMT command:BSSBE Btsep Br<no>:<NE id>BSS-FUNCTIONALBTSMBTSM<no>BTSTRXTRX<no>GET <TRX>NAME=BTS:<no>/TRX:<no>REQATTL=OST/AST

Get TRX:Name=BTS:<no>/TRX:<no>,REQATTL=<AST>&<OST>The states of the TRX are listed in the system response.

3. If the states of the TRX are either administrativeState = Unlocked / operational-State = Disabled or administrativeState = Locked / operationalState = Enabled ,the module is not used for calls anymore. You can start with your maintenance task.

4. If the administrativeState = Shutting Down , the shutdown is in progress. Wait afew minutes and check the state of the TRX again. As soon as the TRX is locked,you can start with your maintenance task.

5. If the TRX is unlocked/enabled , call the OMC to have the TRX shut down. Wait afew minutes and check the state of the TRX again. As soon as the TRX is locked,you can start with your maintenance task.

For an overview of the modules in the TX/RX path, refer to .

For a description of the state/status attributes, refer to Tab. 5.1 "State/Status Attributesof BTSE MOs".

16 A30808-X3247-M281-1-7620


1.5.3 Removing and Inserting Modules

There are two variants for fastening modules in the subracks.

Some modules, e.g. the COBA and COSA, are equipped with a lever mechanism at theirfront panel. For removing or inserting these modules, they can be fastened / unfastenedby swivelling the levers at the top and bottom edges of the module.

Other modules, e.g. the CU, DIAMCO, DUAMCO, FICOM, AC/DC, are fastened withTORX-headed knurled screws. Replacement of these modules requires special tools.

Fig. 1.5 Module Fastening Variants

The TMA (Tower Mounted Amplifier) must be replaced complete with its housing (to bemounted on / unmounted from the mast).

The semi-rigid / flexi cables on the CU, DIAMCO, DUAMCO and FICOM must be fas-tened / unfastened with a torque spanner (2 sizes).

lever mechanism in open position

push together

lever mechanism in locked position torx screw

iIt must be ensured that the modules are only replaced by modules with the same or acompatible HW and SW functional status!Modules with switches or jumpers must be compared with the removed module forsafety reasons.The modules should be removed and inserted as fast as possible, in order to preventreading in false module addresses from the CAN BUS.

A30808-X3247-M281-1-7620 17


MMN:BTSE BS-41

Handling Modules with Code Keys

To prevent the installation of the modules at incorrect mounting positions, code keys areused on all relevant plug-in modules.

Fig. 1.6 Location of the Plug-in Module Code Keys

In order to avoid module and backplane connector damage when modules are removedfrom / inserted into a base station frame, please observe the following:

In general, after having removed a module from a base station frame, please make surethat the module’s code keys (at the rear connector terminals) are mechanically intact,and that a code key plug has not been torn out from its socket and is now jammed in thebackplane.

When replacing a module, please make sure

– that the code keys of the new module have the same setting as those of the old one(see figure below),

Fig. 1.7 Location of the Code Key Number

– that all code keys (also those of the old module) are mechanically intact, and

– that a code key plug has not been torn out from its socket and is now jammed in thebackplane.

When inserting a module, do not use excessive pressure.

1.5.4 Quick Module Replacement

In general, there are 2 replacement procedures:

– the standard replacement procedure

and

– the facilitated, quick replacement procedure (only applicable for some particularmodules).

For the standard replacement procedure, an LMT is required. The modules are lockedand, after their replacement, tested and unlocked via an LMT.

For the quick replacement procedure, an LMT is not required. The module can be re-placed directly and is put into service automatically after a successful replacement (Au-torecovery).Precondition for the quick replacement procedure: the attribute Autorecovery (EAU-TOREC) is enabled.

To check whether this attribute is enabled, perform the LMT command:

BSS

BE Btsep Br<no>:<NE id>

BSS-EQUIPMENT

BTSEP

BTSEP<no>

GET BTSEP NOSWL

REQATTL

EAUTOREC

Get BTSEP NOSWL:NAME=BTSEP:<no>,REQATTL=EAUTOREC

To set this attribute, refer to ITMN:BTSE BS-41, chapter “Setting Attributes for the BT-SE”.

– In order to be able to connect the semi-rigid/flexi cables, insert the prepared moduleas far as necessary. It is recommended to leave about 2 cm (.75’’) distance betweenmodule and backplane connectors.

– Connect all semi-rigid/flexi cables.

– Fully insert the module.

iSpecial Behaviour of Modules that are connected by the CAN bus:If Autorecovery is enabled and such a module is mistakenly locked before it is ex-changed, then this module will recover automatically after it is unlocked.This has no further consequences for the system, but is an unspecified behaviour.

iQuick Replacement Procedure and semi-rigid/flexi CablingModules with semi-rigid/flexi cabling require a special handling!It is important that all semi-rigid/flexi cables are connected before the module is fully in-serted. Otherwise, the module is not put into service. The reason for this is that the au-tomatic recovery process starts as soon as the module comes into contact with thebackplane connectors. Semi-rigid/flexi cables that are not connected during this pro-cess cause errors which will prevent the autorecovery of the module.

MMN:BTSE BS-41

1.6 Closing the Shelter Door

The final step after performing maintenance work is closing the shelter door (cf. “Closethe BTSE door” at the end of most fault clearance procedures).

Fig. 1.8 Closing the Shelter Door: Handle Positions

iImportant Note:

In order to make sure that the ’Door Open’ alarm is really deactivated after closing theshelter door, please do the following:

Close the door, turn the door handle in the clockwise direction and pass over the nor-mal locking position (vertical to the ground), until you feel that it can not be turned anyfurther. Then bring back the handle to the normal locking position (vertical to theground) and press it into the handle latch. The ’Door Open’ alarm goes off.

2 Tasklist

Membrane Filter (MEF)

The MEF is a passive component fitted to the inside of the door. Its purpose is to filterthe air being drawn in by the internal FANs.

Corrosion:

The MEF is made of corrosion resistant materials.

Filter characteristic:

In contrast to a so-called „depth filter“, the MEF does not face the incoming air with afilter tissue but with a smooth membrane surface which offers little chance for dust par-ticles to stick to it irreversibly and no chance to penetrate any further.

This characteristic makes a significant clogging of the filter an unlikely event under nor-mal environmental conditions.

Maintenance routine:

It is recommended to check the air in-let and louvers of a shelter for blocking particles(e.g. leaves).

A MEF must not be cleaned because the membrane might get damaged.

A MEF which is visibly soiled – with no over temperature alarm occurred – does not needto be replaced due to described filter characteristic above.

If an over temperature alarm occurs, check the following before MEF replacement:

or false alarm (e.g. defective cables, ACTC, ACTP)

– check air in-lets for blocking particles

– check for defect FAN(s)

– check for false alarm (e.g. defective cables, ACTC, ACTP)

If all other failure causes could be excluded, the MEF must be replaced by a new oneand the old one sent to the relevant service center.

Note: The symbol on the integral frame indicating the top of the MEF has to be noticedwhen fitting it to the inside of the door.

Heat Exchanger (HEX)

Preventive maintenance for HEX

Dust accumulation may occur on fan impellers and so must be cleaned every 12 monthsto ensure optimum performance and prevent possible vibration which could damage thebearings and reduce its life span.

22 A30808-X3247-M281-1-7620


Recuperator cleaning:

Dust accumulation may occur on recuperator plates, especially the external air-ways,and should be cleaned every 12 months to ensure optimum performance.

In areas of general contamination, the recuperator may be cleaned with compressed airor a powerful vacuum, or in special cases with water spray or a ph-neutral soap/watersolution to the external air-ways only.

For coastal or high contamination areas, it is recommended that the HEX is removedfrom the door of the shelter.

With the HEX unit removed from the door the recuperator can be extensively cleaned.The recuperator does not need to be removed from of the HEX for cleaning.

An exchange of the recuperator is generally not possible.

Water drain of HEX:

Dust sediment may block the drain of the HEX so that water will not pass through theinternal circuit of the shelter. Every 12 months the water drain must be cleared andcleaned to ensure that it is free of contamination.

With the HEX unit removed from the door the water drain may be extensively cleaned.The water drain is via a tube on the lower left side in the housing of the HEX.

Use of water spray and compressed air:

Do not spray water in and around the fans

Use water spray or a ph-neutral soap/water solution only for external air-ways of the re-cuperator.

When using compressed air and/or water spray, be careful not to damage the foam sealbetween the recuperator and the HEX housing.

All residue from the cleaning process should be removed.

HEX Corrosion:

The HEX is corrosion resistant because the housing, recuperator and fan wheel are allmade of plastic.

3 Fault Clearance Procedures for Modules andInterfaces

24 A30808-X3247-M281-1-7620


3.1 Abis

1 Open the BTSE door

To verify an Abis alarm you have to open the BTSE door and check the LEDs ofthe COBA/COSA.

2 Check the LEDs on the COBA/COSA

You can recognize an Abis alarm by the red LEDs for Abis 1 to Abis 8 alarm onthe COBA/COSA.

The Abis LEDs indicate the respective Managed Object BPORT, e.g.:

iIn some cases, Abis alarms originate from loose or damaged PCM cables on the BTSEAbis interface (OVPT) and in the corresponding distribution frame in BSC direction.Therefore, the relevant cables must be checked first, according to the following proce-dure.

Typical Abis alarms concerning cable problems may be indicated by the alarm mes-sage- BPORT - Loss of signal

iBPORT is the logical object that is related to the Abis interface (OVPT).The Abis lines are also referred to as PCM lines.

Abis 1 corresponds to the Managed Object BPORT 0,Abis 2 corresponds to the Managed Object BPORT 1, etc.

3.3 AC/DC

The managed object ACDCP is related to the DCBCTRL, not to the AC/DC module itselfand therefore exists only once.

In BS-240 II / 240XL II the AC/DC system is not configured as managed object. To makeAC/DC alarms visible, Environmental Alarms have to be configured (see ITMN:BTSEBS-41, Creating the Alarm Configuration (ENVABTSE)).

If the AC/DC modules are not equipped in redundant configuration, the system uses thebackup battery for power supply and may be in ’Emergency Configuration’.

In redundant configuration only one AC/DC module can be replaced at the same timewithout any interruption.

The fault message indicates the address of the corresponding DCBCTRL.

Examples for Alarms in the Power Supply System

Error ID 20495 battery breakdown

Error ID 20496 battery charching fault

Error ID 20497 -48V out of tolerance

Error ID 53266 mains breakdown

1 Interpret the Fault Message ......(see 5.4)

Note the values specified in the fault message, for example:

– Module(s) ??

– BTS-no ??

– Rack-no ??

– Module address ??

Use these values for command input.

Use the logical address to find the mounting location of the module(s). ......(see 4.3)

iNote that the failure cause may be located in any module of the power sypply system:- the module(s) addressed in the error message- AC/DC- AC Panel or ADP- DCBCTRL- BatteryIt is recommended to start with the replacement of the module which is addressed inthe fault message. Afterwards - if the error is still there - to take the other modules inthe power supply system into consideration.

iModule CU may be removed while power is on.

iThe module CU may also be an EDGE CU (ECU) or a GMSK CU (GCU).

iIt is possible to use CUs, ECUs, GCUs or FlexCUs, but please note the following:Since the GSM 1800 GCU has more RF output power than the GSM 1800 CU, mixedcell configurations might result in slight changes of some performance counters andCU dependent coverage. It is not recommended to use the antenna hopping mode inthis configuration.The output power of ECUs can be reduced to allow mixed cell configurations with CUs(see ITMN:BTSE BS-41).For more information on the RF output power of the various CU types, please refer toTED:BSS BS-40/41.If ECU,FlexCU and CU/GCU are used for the same cell in EDGE mode, antenna hop-ping is not possible.

Do the LED switch off after a few seconds? Y h...4N h...6

iIn most cases, alarms in the TX/RX path originate from loose or damaged cables.Therefore, the relevant cables must be checked first, according to the following proce-dure.

If the alarm cannot be cleared in this way, the suspected modules must be replaced.Note that the failure cause may be located in any module of the TX/RX path:- the module(s) addressed in the error message- combining equipment- antenna.

It is recommended to start with the replacement of the module which is addressed inthe fault message. Afterwards - if the error is still there - to take the other modules inthe TX/RX path into consideration.

iTo make sure that no calls are lost, check whether the corresponding TRX is shutdown before cables/modules are disconnected. If the TRX is still in use, call the OMCto have it shut down. For more information, refer to 1.5.2 "Avoiding the Loss of Calls".

5.1 HW/SW Compatibility During Download from LMT/BSC

This feature allows a compatibility check of the swLoad and the current HW situation ofthe BTSE, there by preventing a download of a swLoad which will not run on the specificBTSE.

This check is done by means of a compatibility matrix - the Version Attachment Mecha-nism (VAM) file which is the second file of the swLoad. The check is carried out whenthis VAM file is received in the BTSE. On negative result the further download of theswImages is stopped.

This check is only available in the load phase.

swLoad : GSM notation for a complete SW package containing all the load SW of a net-work element.

swImage : GSM notation for the load SW package for a single module inside a networkelement.

VAM file : represents the context between the swImages and the HW-SW compatibility.

Meaning of Other Information:

All other bytes are not used.

If the first byte of the string “Other Information” is H’01, the result of the VAM check isnegative. In this case, it has to be checked whether the HW version of the replaced mod-ule is supported by the actual SW version according to the stock list/release note. If theHW version is not supported, the module must be replaced by one with a supported HWversion.

5.2 State/Status Attributes of BTSE Managed Objects

The following state/status attributes are used for BTSE MOs:

State/Status Attribute State/Status Explanation

Administrative State(AST)

This state informs whether or not the MO is permitted to provideservice.

Locked The related MO is not permitted to provide service, but is addres-sable for maintenance tasks and fully operable (it can, for exam-ple, be tested). This state can be brought about via the LMT“Lock” command.Note: at the BTSE, only HMOs can be locked/unlocked.

Shutting Down The MO is currently shutting down, i.e. ongoing calls are not in-terrupted, but no new calls are permitted.This state cannot be brought about via LMT at the BTSE.

Unlocked Service is permitted.This state can be brought about via the LMT “Unlock” command.Note: at the BTSE, only HMOs can be locked/unlocked.

Operational State(OST)

This state informs whether or not the MO is able to provide ser-vice.

Enabled (ena) The MO is able to provide service.(Exception: The MOs “RACK”, “BTSE” and “ENVABTSE” arealways “Enabled”, even if, for example, a service rack is notinstalled.)

Disabled (dis) The MO is not able to provide service.

Alarm Status (ALS) This status reports the severity level of active alarms. If morethan one alarm is active, the level of the alarm with the highestseverity level is reported.

Critical At least one active alarm with severity level “critical”(see 5.3.3.1).

Major At least one active alarm with severity level “major” (see 5.3.3.2).

Minor At least one active alarm with severity level “minor” (see 5.3.3.3).

Cleared No active alarms.

Availability Status This status reports details on AST or OST.

In Test (tst) Intrusive test under progress.

Failed (fail) MO is defective/not operable.

Power Off (pof) The power of the MO is switched off.

Degraded (deg) The service is degraded.

Off Line (ofl) The creation of the MO is in progress.

Dependency (Dep) The MO cannot operate because of another MO on which it de-pends.

Not Installed (noi) The MO is not installed.

Null Value (nul) Value after the creation of an MO (+Disabled/Locked).Certain processes still in progress (e.g. alignment).MO TRX: transient failure of a HMO.

Procedural Status(PRS)

This status reports whether or not the MO performs an initializa-tion procedure.

Initialising (ini) Initialization is in progress.

Null Value (nul) No initialization

Standby Status (STS) This status reports information on redundant MOs.

Null This value is used in combination with OST “Disabled”.

Providing Service This value is used in combination with OST “Enabled”/AST “Un-locked”. The MO provides service.

Cold Standby The MO is able to provide service but it is either not active or it islocked.

5.3.2.5 Environmental ErrorsThese errors depend on environmental conditions e.g. temperature, door open orsmoke.

In general, these faults are signalled to the ACT module.

5.3.3 Perceived Severity

The severity level indicates to what extent the functionality of the BTSE is affected. Thefollowing values are used:

5.3.3.1 CriticalThe critical severity level indicates that a service affecting condition has occurred andan immediate corrective action is required. Such a severity can be reported, for exam-ple, if an equipment related managed object MO breaks down completely.

5.3.3.2 MajorThe major severity level indicates that a service affecting condition has developed andan urgent corrective action is required. Such a severity can be reported for example, ifthere is a severe degradation in the capability of the equipment related managed object(MO).

5.3.3.3 MinorThe minor severity level indicates the existence of a non-service affecting fault conditionand that corrective action should be taken in order to prevent a more serious (for exam-ple, service affecting) fault. Such a severity can be reported, for example, when the de-tected alarm condition is not currently degrading the capacity of the equipment relatedmanaged objects (MO).

5.3.3.4 WarningThe warning severity level indicates the detection of a potential or impending service af-fecting fault, before any significant effects have been detected. Actions should be takento further diagnose (if necessary) and correct the problem in order to prevent it from be-coming a fault causing more severe interference to services.

5.3.4 Trend Indication

This parameter specifies the current severity trend of the equipment related managedobject.

5.3.5 Immediate Defense Action

The immediate defense action is performed by the BTSE software to try and solve theproblem. If there is no corresponding defense action, NA is reported.

5.5 BTSE Components

5.5.1 BTSE Components Overview

For a system overview of all BTSE components (modules, frames, racks and managedobjects), refer to chapter 4 "Tables, Lists and Figures"

5.5.2 Numbering of BTSE Components

5.5.2.1 General Rules

Relative Numbering

In general the relative numbering (in the meaning of logical numbering) of the units startswith the figure zero (0). That means the first of a set of devices, modules or racks / shel-ters gets the number 0, the next one the number 1 in sequence, etc.

With the exception of Abis-lines. The numbering starts with 1, 2, 3 ...

212 A30808-X3247-M281-1-7620


5.5.2.2 Specific Rules

Shelter Numbering

The first shelter in a BS-41 is called Base Shelter, and gets the number 0. Altogether,beside one Base Shelter a maximum of 4 Service Shelters can be installed for one BS-41 (not BS-41U).

The rule for numbering of the shelters is shown in the table below. Note, that the num-bering of the Service Shelters always begins with the number 4.

Slot Numbering inside the Shelters

In a shelter slot numbers are defined for accommodation of CUs, ACOMs and MUCOs.There are 4 CU slots (0...3), 2 ACOM slots (0,1) and 1 MUCO slots (0). Additionally inthe Base Shelter 4 CORE slots are defined for housing the core units and their redun-dant ones.

The HPDU 0 is located at the left side of the shelter and the HPDU 1 is located at theright side of the shelter.

The Figure Fig. 4.6 shows as an example the arrangement of a BS-41 with Base Shelter(Shelter 0), 1 Service Shelter (Shelter 4).

5.5.3 Remote Inventory Data

The function “Remote Inventory” of the Siemens Basestation System performs electron-ic, non volatile storing of the complete, individual product identification data (PID) ofeach inventory object.

Modules that have their inventory data on board are called ob_RIUs (on-board RemoteInventory Units). The PID of these ob_RIUs is automatically loaded to the inventory datafile (IDF).

In order to include inventory data of objects without a non volatile storage (e. g. frames,racks, OEM components), the data of these so called nob_RIUs (not on-board RemoteInventory Units) are entered into an inventory data table (IDT) via the LMT and the offlinetool “IDF editor”. These data is stored on the COBA as a nob_RIU file (NOB). Supple-mented with a footer and header, the IDT can be exported and stored as an inventorydata file (IDF) for backup purposes.

In case of the replacement of a nob_RIU component, the NOB file must be updatedmanually and the backup IDF-file with the inventory data, which is stored on site, mustbe updated as well.

In case of a COBA replacement, the inventory data that was stored on the removedCOBA must be rebuilt. This can be done by using the backup IDF-file.

For ob-RIU replacements the inventory data file will be updated automatically.

5.6 Diagnostics / Test

5.6.1 General

In general the diagnosis subsystem is for testing the functionality of BTSE HW resourc-es to detect and localise hardware faults. The verification of the functionality of a new orreplaced hardware unit before operation is an especially important feature of diagnosis.

The task of diagnosis is to perform tests for the BTS processor modules, initiated fromthe LMT

Replacement of analog modules can only be seen to have been successful by reactivat-ing the BTSE.

5.6.2 Requirements for Starting the BTSE Module Test

The module test is controlled by the LMT. It is therefore necessary that the LMT isplugged in at the plug position and that it is logged in. The principle sequence is as fol-lows:

– change the administrative state from unlocked to locked

– start the module test

– change the administrative state from locked to unlocked

The requisite command sequence is as follows:
