4. INTRODUCTION OF THE TOOL

Recovering Flexi System Module (FSM) with the Restore Factory Settings (RFS) - tool introduces apowerful onsite recovery step and thus can prevent possible FSM swap for repair. The RFS - toolshall be utilized whenever the regular recovery procedures (e.g. resets, reconfiguration, sw

download, etc) are not possible or they do not recover the fault state.

With the RFS- tool Flexi System Module is restored to a plain, factory delivered condition. The RFStool is an easy to use MS executableapplication, which deletes all the existing configuration,database and license files from FSM memory and then restores the essential databases and defaultSW release binaries into FSMx module.

As a result FSM databases are cleaned and fixed and FSM will start with default sw release inuncommissioned state (factory state). Now the FSM in un-commissioned state can be integratedagain to a BTS Site and set to operational state with SW upgrade and commissioning steps.

The RFS tool is not related to any BTS hardware or sw configuration and thus can be executed forBTS site without removing the FSM module. Furthermore, any standalone FSM can be operated with

the RFS tool, which enables recovering modules in warehouses and stocks as well on test bed andpre-installation locations.

5. DESCRIPTION OF THE TOOL

5.1 When to use the RFS recovery

The RFS provides a fundamental onsite recovery step for problem situations, which have not beensolved by software re-installation and/or re-commissioning using BTS Site Manager.

In such situation the RFS recovery should be always executed before proceeding to swapping theFSM module and dispatching it as a faulty to NSN Hardware Services.

RFS is expected to recover all the fault states described below, unless they are not caused by amore severe fault e.g. HW failure in a module.

1) A problem happened dur ing insta l lat ion/commiss ioning phase when new/replacement uni t

has been instal led to network.

RFS will replace existing BTS configuration database and will update BTS SW to FSMx module.There is no need to remove FSMx from BTS Site in order to run RFS recovery.

2) BTS Site faul t invest igat ion cannot be done due to exist ing si te conf igurat ion and the non -

operational state of runni ng BTS SW.

RFS will prepare a non-commissioned BTS Site (except TRS commissioning that remains).FSMx has been defaulted to a state that whole BTS Site can be rebuilt.

3) SW mismatches between di f ferent Flexi BTS HW mo dules. SW download progress may not

star t at al l or is p ar t ly downlo aded to BTS but not comp letely. BTS SW wil l refuse to al low

any fur ther act ions. Power m ay have been sw itched of f -on between upgrade at tempts andBTS cannot fu l ly recover .

RFS will remove existing BTS SW configuration and will upload and flash new BTS SW files toFSMx memory.

4) Comm issioning steps cannot be successfu l ly comp leted. BTS cannot become operat ional

wi th no rmal re-comm issioning steps. SCF f i le may prevent fur ther re-commission ing

attempts o r som e Flexi BTS modu le cannot reach operational state or there is a fake Flexi

BTS mod ule vis ib le.

RFS will remove existing hardware configuration and site commissioning file(s). FSMx and wholeBTS will be in not commissioned state after successful recovery scenario.

5) BTS Site Manager con nection is not possib le.

RFS will remove existing configuration and database files and will upload new ones duringrecovery scenario. BTS will be restarted with new information.

6) FSMx memory c ontent is suspected to be corrupted. A permanent fai lure is detected dur ing

BTS startup phase. Internal SW management s elf test does not allow BTS startup to

proceed.

RFS recovery will replace existing configuration with default BTS database and SWconfiguration.

7) Some units (e.g. FSPs) do no t respond at all due to SW failure. SW down load canno t be

star ted/completed since al l necessary uni ts are not responding.

RFS recovery can be run for FCMD and FSPs subunits one by one and complete recovery forwhole FSMx unit.

8) FSMx cannot be reused in another BTS si te due to exist ing si te conf igurat ion and l icensingconf igurat ion.

RFS will remove existing BTS configuration completely and clears stored Target Id and therelated Last Used Timestamp -value from FSMx. After BTS SW activation of RFS recoveryscenario, new Target Id value will be generated for FSMx unit (because nothing is stored intoFSMx memory).

5.2 Functional description

RFS tool runs following procedure phases automatically and displays progress informationaccordingly.

STEP 1- FCMD - Establishes connection to module- FCMD - Reads unit identification and check compatibility of FSM module HW and SW type- FCMD - Read unit identification information, check RFS compatibility- Checks availability subunits (FCMD and FSP(s))

STEP 2- FCMD - Clears existing BTS configuration, database, license and BTS SW binary files

- FCMD - Uploads new BTS configuration & database files and BTS SW binaries- FCMD - Stores permanent BTS SW files to FSMx flash memory- FCMD - Clears Target ID and related Last Used Timestampvalue from FSMx memory

STEP 3- FSP - Establishes connection to module- FSP - Clears existing BTS configuration files and BTS SW binaries- FSP - Uploads new BTS SW binaries- FSP - Stores permanent BTS SW files to FSP flash memory

STEP 4- Creates and saves report of conducted actions- Activates new BTS SWFSMx will be set to reset- Notifies to close application.

Typically 16 to 17 minutes is required for RFS to recover FSME with the normal RFS-tool run.

Execution duration may vary due to different- amount of FSP units in FSMx (3 FSPs in FSME, 2 FSPs in FSMD, 1 FSP in FSMC)- amount and size of existing files to be deleted- storing speed of new files due to varying in flash memory hardware- command line argument is set to pass recovery for a sub-unit (FCMD/FSP)

More detailed information regarding the procedure and recovery run options is described in UserGuide document delivered with the RFS tool.

5.3 Outcome of the recovery on BTS site

5.3.1 Commissioning and configuration

After recovery executed with the RFS- tool, the FSM will start in un-commissioned state. In case ofthe RFS recovered module is a master system module, the BTS commissioning and configurationdatabases are removed completely and BTS will restart in un-commissioned state (factory settingsstate).

TRS commissioning will not be cleared during RFS recovery in case FTM transport unit is connectedto FSM. Also, no operation is done on RF modules or on the extension system module, if suchmodules are connected to FSM.

Figure 1 Example BTS Hardware and BTS alarms view after recovery

5.3.2 SW release version

The RFS-tool stores WN7.0 2.1 (WN7.0_1207_575_09) BTS SW release to FSM and the sw releasewill be active sw in use after recovery has been completed. No any previous sw versions will beremaining on FSM.

A compatible BTS Site Manager version is accordingly WN7.0_1207_1858_00.

5.3.3 Licensing

All the license key files as well the Logical Target ID of FSM for licensing will be cleared during therecovery. Later, when the module is again integrated and commissioned in to use, a new Target IDwill be generated or an existing Target ID saved to Radio Module will be recalled according to rulesof feature RAN1849: BTS LicensingLogical Target ID for Flexi BTS.

6. INSTRUCTIONS

6.1 How to get the tool

The RFS tool is delivered with RestoreFactorySettings.zip-file and is available on WN7.0 2.2 BTSSW release delivery page in Nokia Siemens Networks Online Services.

Later, the RFS tool will be available in NOLS with all the WN7.0 2.x maintenance releases.

6.2 How to prepare BTS site

RFS tool is not related to any BTS hardware configuration and thus it can be run in flexible way.

In case of recovering the master FSM, there is no need to remove the master FSM module orany of the power/optical cabling in the existing BTS setup when using RFS tool.Recovery will

manipulate only FSM; therefore the other Flexi BTS modules will stay untouched and can remainin the hardware configuration. TRS commissioning will not be cleared during RFS recovery incase FTM transport unit is connected to FSMx

In case of recovering the extension FSM, only the optical fibers (OPT-EXT1 and POT-EXT2)connecting the module to the master FSM must be disconnected.

Any standalone FSM without FTM installed can be operatedwith the RFS tool as well. RFS-

tool should always work without FTM. This enables recovering modules also in warehouses andstocks as well on test bed and pre-installation locations.

No working BTS Site manager connection is required to start recovery with RFS-tool.

RFS recovery does not require any special pre-condition for sw operation state. It can be startedwhen FSMx is up and running, or at the very same time as FSMx is started. Latter method maybe required with some conditions

If the Ethernet Port Securityfeature for has been active previously in the BTS, the feature needfirst to be set disabled to allow direct access for the tool from the local management port (LMP).

Alternative is simply to disconnect the FTM from FSM.

6.3 How to prepare - user

1. Unzip the RestoreFactorySettings.zip to a local folder on PC.The file contains a MS Windowsexecutable application and all supporting files needed for a recovery session.

2. Open User Guide document and read the operating instructions and notes.

3. Connect PC to the LMP port of FSMx module to be recovered

4. Run recovery procedure with RFStool as instructed in the User Guide document
