1 Safety Rules and Precautions


This chapter contains the following safety rules and precautions:

Safety rules for equipment under power

Electrostatic precautions.

Injury from EquipmentPossible death or serious physical harm to personnel and damage to equipmentmay result from mishandling.While performing any maintenance tasks or procedures, you must follow anylocal safety requirements, and those mentioned in General Safety Instructionsfor Field Operations and this chapter.

3BK 21256 AAAA PCZZA Ed.10 9 / 38


1.1 Safety Rules for Equipment Under PowerFor maintenance purposes, field operators may have to work on equipmentunder power (-48 VDC or -60 VDC). This means that it is possible to touchsome parts under power, that are only protected by heavy fuses. Maintenanceactivities must be carried out carefully to avoid short circuits and to preventserious personal injury.Remove all conductive objects from the hands, such as rings, bracelets,metallic wrist watches and so on. Use appropriate insulated tools formaintenance activities.

1.2 Electrostatic PrecautionsThe following electrostatic precautions must be observed:

1.2.1 Environment

Ensure that work benches, stools, and floor mats have a conducting surfaceconnected to ground. Before handling static-sensitive components andassemblies, ground yourself to the conducting surface using an anti-staticwrist strap.

When handling static-sensitive components and assemblies, do not wearor use clothes made of wool, nylon or any other synthetic material. Suchfabrics are major sources of static build-up.When handling static-sensitive components and assemblies, do not usegloves and finger covers, unless they are made of cotton.

1.2.2 Tools

Ensure that all the tools which come into contact with static-sensitivecomponents are at the same voltage level as the conducting work surfacesand floor mats.These tools include soldering irons, oscilloscopes, power supplies, andmetal parts of tools and fixtures that are used to hold, assemble or test PBAs.

Do not use rough cleaners or erasers to clean the gold-plated contactson PBAs.

Do not mark a PBA with a lead pencil or any other writing instrument.

Do not use synthetic brushes to clean equipment, and do not use drycleaning methods.

10 / 38 3BK 21256 AAAA PCZZA Ed.10


1.2.3 Transportation and StoragePack all containers used to transport and store static-sensitive components,and use aluminium container tubes if possible. If not, insert the componentterminations into electrically conductive foam.

Before shipping a PBA, wrap it in a conducting synthetic bag or in aluminiumfoil. Also pack the PBA in a polyethylene transport box.

Before shipping a PBA which has MOS components, ensure that anappropriate warning symbol is displayed on the package.

Store spare PBAs in their appropriate polyethylene boxes. Keep the boxesclosed except when access to their contents is required.

Do not store PBAs in an area where the air is polluted with smoke, dust,dangerous gases or other air-borne particles that may cause damage.

Do not stack PBAs side-by-side or on top of each other with the boardsurfaces or components in contact with one another.

Before cleaning a PBA, remove or disconnect the damage protection, suchas protective foam, to allow the PBA to be cleaned thoroughly. Replace thedamage protection upon completion of the task.

1.2.4 Components and PBAsComponents and PBAs not in protective containers, must only be handledby trained personnel in static-controlled work areas.

Before removing a PBA from an equipment rack, discharge any static bytouching the metal frame of the rack with your hand.

Always handle a PBA by the edges.

Do not handle or carry a PBA by any of the mounted components.

Do not handle a PBA by the gold-plated contact terminals and do not applydirect pressure to the components.

Do not touch PBA connection pins or conductor paths.

Do not touch PBAs with wet hands.

Place PBAs that have been removed during maintenance with the solderedside downwards on a conductive surface.

Do not scratch or rub the soldered side of a PBA with a sharp or roughobject.Do not repair PBAs in the switch room.

Do not handle components and assemblies by their leads.

Do not use excessive force when inserting connection boards.

3BK 21256 AAAA PCZZA Ed.10 11 / 38


1.2.5 Handling Optical Fiber DevicesDepending on installed options the equipment may contain fiber optic devicesthat can radiate laser beams:

Do not look directly in the laser beam

Take into account that infrared laser radiation is not visible. Additional labelscan be added to classify the laser.

Respect the warnings given by labels provided on equipment.

1.2.6 Handling Coaxial and Optical Fiber CablesWhen handling coaxial or optical fiber cables:

Do not cut coaxial or optical fiber cables to adjust the cable length.Do not bend to tighten the coaxial or optical fiber cable.Furthermore, for handling coaxial or optical fiber cables respect the cablemanufacturer specifications.

3 9125 TC RITs

3.1 Replace MT120In the 9125 TC rack there are only 9125 TC Transcoding Boards for Ater-E1(MT120).The 9125 TC is structured in four subracks, each containing up to twelveMT120.There are three types of MT120 boards: MT120 (legacy), MT120 WideBand(WB) and MT120 NarrowBand (NB).The following procedure applies for all types of MT120 boards.The part number of the MT120 board is:

3BK 08882 xx for MT120 legacy

3BK 27897 xx for MT120 WB

3BK 28280 xx for MT120 NB.

There are two means to perform a MT120 board replacement on the 9125TC rack:

The first is by using the Replace Command on the TC NEM. This commandis used to ease the replacement procedure; the actions of the operator arelimited to the strict necessary. The only constraint is that the TC NEM mustbe able to retrieve the current configuration of the MT120 board to replace(this includes the SW version and the configuration parameters to run theMT120). For details see Replace a Board in 9125 TC NEM User Guide.The second means to replace the MT120 is needed when the TC NEMcannot retrieve the current configuration of the board to replace.

3.1.1 Tools and MaterialsYou must have a TC NEM and an:

RS-232 asynchronous communication link cable to connect it to a MT120legacy board (3BK 07951 AA)Ethernet crossed cable to connect it to a MT120 NB/WB board.

Only one TC-NEM application should be connected to the TC rack at one time,regardless of the software management mode of the MT120 boards.If the MT120 boards are running in:

TCIL management mode, only one TC-NEM can be connected (via MMIor Serial) to the TC rackHSI, management mode, only one TC-NEM can be connected (via IP)to the TC rack at a time.

3.1.3 Procedure 1

Note: This procedure must be used when replacing a board by a similar one (MT120by MT120, MT120 WB by MT120 WB or MT120 NB by MT120 NB).

3.1.3.1 MT120 in TCIL or no Direct Connection to the BoardTo replace a MT120 board using the Replacement Command:1. Unlock and open the front door of the TC rack.2. Connect the TC NEM to the TC rack; connection to any MT120 board with

no autotest failure, indicated by a permanent red LED.3. Execute the MT120 board replacement command on TC NEM. For details

see Replace a Board in 9125 TC NEM User Guide.

Retrieve of DataIf the TC NEM can retrieve the current configuration of the MT120 board toreplace the command continues. Otherwise the operator must perform amanual replacement of theboard (see procedure 2).

4. The operator must check that the PCM links of the MT120 he wants toremove carry no telecom traffic (indicated by the link connection statusDISCONNECTED on the display) (recommended).

5. Unbolt the MT120 board. As there is no disable command, carefully extractthe MT120 board from the backplane and fully withdraw it from the slot.

6. Replace it by a new one of the same type.

Backplane DamageDo not use excessive force when inserting the new MT120 board.

7. Follow the replacement procedure.8. After the new board is up and running, make sure that the [ Connect ] button

of the TC-NEM is pressed in order to continue the procedure using theReplacement Wizard dialog box.

9. At the TC NEM check the Qmux clusters and MT120 mapping.10. Set up the MT120 Remote Inventory (e.g. commissioning date, network

identity, logical site name, etc.). For details see Modify the Remote Inventoryin 9125 TC NEM User Guide.

11. Disconnect the TC NEM.12. Shut the front door of the TC rack and lock it.

3.1.3.2 MT120 in HSI or MT120 in TCIL with Direct Connection to the BoardTo replace a MT120 board which is running in HSI management mode ( orMT120 in TCIL with direct connection available) :1. Unlock and open the front door of the TC rack.2. Using a direct connection (serial cable for MT120 legacy or Ethernet

crossed cable for MT120 NB/WB board), physically connect to the board tobe replaced.

3. Start the TC-NEM on serial (for MT120 legacy) or MMI (for MT120 NB/WB)connection.

4. Execute the MT120 board replacement command on TC NEM. For detailssee Replace a Board in 9125 TC NEM User Guide.

5. The operator must check that the PCM links of the MT120 he wants toremove carry no telecom traffic (indicated by the link connection statusDISCONNECTED on the display) (recommended).


7. Replace it by a new one of the same type and follow the replacementprocedure.


8. If the new board is a MT120 NB/WB board you must:

check its IP address

configure TC NEM PC Ethernet network interface so as the IP addressof the TC NEM PC is in the same subnetwork with the IP address ofthe new MT120 NB/WB board

start the TC-NEM on MMI connection using the IP address of the newMT120 NB/WB board.

9. After the new board is up and running, make sure that the [ Connect ] buttonof the TC-NEM is pressed in order to continue the procedure using theReplacement Wizard dialog box.

10. At the TC NEM check the Qmux clusters and MT120 mapping.

Note: Even if the new board is running in TCIL mode and the old one was running inHSI mode, at the end of the replacement the new board will be running in HSIwithout any Change Mode command necessary.

11. Set up the MT120 Remote Inventory (e.g. commissioning date, networkidentity, logical site name, etc.). For details see Modify the Remote Inventoryin 9125 TC NEM User Guide.
