4. INTRODUCTION OF THE TOOL Recovering Flexi System Module (FSM) with the Restore Factory Settings (RFS) - tool introduces a powerful onsite recovery step and thus can prevent possible FSM swap for repair. The RFS - tool shall 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 RFS tool is an easy to use MS executable –application, which deletes all the existing configuration, database and license files from FSM memory and then restores the essential databases and default SW release binaries into FSMx module. As a result FSM databases are cleaned and fixed and FSM will start with default sw release in uncommissioned state (factory state). Now the FSM in un-commissioned state can be integrated again 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 for BTS 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 and pre-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 been solved 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 the FSM 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 a more severe fault e.g. HW failure in a module. 1) A problem happened during installation/commissioning phase when new/replacement unit has been installed 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 fault investigation cannot be done due to existing site configuration and the nonoperational state of running 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 different Flexi BTS HW modules. SW download progress may not start at all or is partly downloaded to BTS but not completely. BTS SW will refuse to allow any further actions. Power may have been switched off-on between upgrade attempts and BTS cannot fully recover. RFS will remove existing BTS SW configuration and will upload and flash new BTS SW files to FSMx memory. 4) Commissioning steps cannot be successfully completed. BTS cannot become operational with normal re-commissioning steps. SCF file may prevent further re-commissioning attempts or some Flexi BTS module cannot reach operational state or there is a fake Flexi BTS module visible. RFS will remove existing hardware configuration and site commissioning file(s). FSMx and whole BTS will be in not commissioned state after successful recovery scenario. 5) BTS Site Manager connection is not possible. RFS will remove existing configuration and database files and will upload new ones during recovery scenario. BTS will be restarted with new information. 6) FSMx memory content is suspected to be corrupted. A permanent failure is detected during BTS startup phase. Internal SW management self test does not allow BTS startup to proceed. RFS recovery will replace existing configuration with default BTS database and SW configuration.

7) Some units (e.g. FSPs) do not respond at all due to SW failure. SW download cannot be started/completed since all necessary units are not responding. RFS recovery can be run for FCMD and FSPs subunits one by one and complete recovery for whole FSMx unit. 8) FSMx cannot be reused in another BTS site due to existing site configuration and licensing configuration. RFS will remove existing BTS configuration completely and clears stored Target Id and the related Last Used Timestamp -value from FSMx. After BTS SW activation of RFS recovery scenario, new Target Id value will be generated for FSMx unit (because nothing is stored into FSMx memory).

5.2 Functional description RFS tool runs following procedure phases automatically and displays progress information accordingly. 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 Timestamp –value 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 SW – FSMx 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 User Guide 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 of the RFS recovered module is a master system module, the BTS commissioning and configuration databases are removed completely and BTS will restart in un-commissioned state (factory settings – state). TRS commissioning will not be cleared during RFS recovery in case FTM transport unit is connected to FSM. Also, no operation is done on RF modules or on the extension system module, if such modules are connected to FSM.

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 release will be active sw in use after recovery has been completed. No any previous sw versions will be remaining 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 the recovery. Later, when the module is again integrated and commissioned in to use, a new Target ID will be generated or an existing Target ID saved to Radio Module will be recalled according to rules of feature RAN1849: BTS Licensing – Logical 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 BTS SW 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 or any 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 remain in the hardware configuration. TRS commissioning will not be cleared during RFS recovery in case 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 operated with the RFS tool as well. RFStool should always work without FTM. This enables recovering modules also in warehouses and stocks 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 started when FSMx is up and running, or at the very same time as FSMx is started. Latter method may be required with some conditions



If the Ethernet Port Security –feature for has been active previously in the BTS, the feature need first 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 Windows executable 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 RFS –tool as instructed in the User Guide document
