Introduction

Figure 3 View of torx screw fastening

The TMA must be replaced together with its housing (to be mounted on/unmounted from the mast).

Semi-rigid/flexi cables, for example on CU, DUAMCO, FDUAMCO, must be fas-tened/unfastened with a torque spanner (2 sizes).

g It must be ensured that all cables are fastened correctly. Make sure that the connec-tors are aligned straight on the screw threads. Then tighten the cable connector coupling nuts manually. The position and alignment is correct if the coupling nuts can be turned easily.

Finally, fasten the cables by tightening their coupling nuts with a torque wrench.

g It must be ensured that the modules are only replaced by modules with the same or a compatible HW and SW functional status!Modules with switches or jumpers must be compared with the removed module for safety reasons.

The modules should be removed and inserted as fast as possible, in order to prevent reading in false module addresses from the CAN bus.

Handling modules with code keysTo prevent the installation of the modules at incorrect mounting positions, code keys are used on all relevant plug-in modules.

Figure 4 View of location of the code keys

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

In general, after having removed a module from a base station frame, please make sure that the code keys of the module (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 the backplane.

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 4 View of location of the code keys), 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 the

backplane.

When inserting a module, do not use excessive pressure.

Introduction

The facilitated, quick replacement procedure (only applicable for some particular modules).

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

For the quick replacement procedure, an LMT is not required. The module can be replaced directly and is put into service automatically after a successful replacement (Autorecovery). Precondition for the quick replacement procedure: the attribute Autorecovery (EAUTOREC) is enabled.

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

BSSBE Btse* Br:BSS-EQUIPMENTBTSE*BTSE*GET BTSE* NOSWLIn the Object Details you will find the attribute and the value for EAUTOREC.

You can set this attribute via the command SET BTSE* EAUTOREC:.g Autorecovery is possible for several modules but not always recommendable. Refer

to the corresponding fault clearance procedure.

g Special behaviour of modules that are connected by the CAN bus:If autorecovery is enabled and such a module is mistakenly locked before it is exchanged, then this module will recover automatically after it is unlocked.

This has no further consequences for the system, but is an unspecified behaviour.

g Quick replacement procedure and semi-rigid/flexi cablingModules with semi-rigid/flexi cabling require special handling.

It is important that all semi-rigid/flexi cables are connected before the module is fully inserted. Otherwise, the module is not put into service. The reason for this is that the automatic recovery process starts as soon as the module comes into contact with the backplane connectors. Semi-rigid/flexi cables that are not connected during this process cause errors which will prevent the autorecovery of the module. In order to be able to connect the semi-rigid/flexi cables, insert the prepared module

as far as necessary. It is recommended to leave about 2 cm (.75) distance between module and backplane connectors.

Connect all semi-rigid/flexi cables. Fully insert the module.

2 Safety instructions

2.1 Definitions of alert categoriesThe safety instructions are divided into three categories:.

2.1.1 Electrostatically sensitive components (ESD) precautions

Figure 5 ESD symbol

Many system modules are equipped with electrostatically sensitive components (marked by an ESD symbol). Therefore, ESD precautions must be taken when removing and inserting modules. During module replacement, personnel must wear a conductive wrist strap to discharge electrostatic charging. Before touching modules, lines or com-ponents, make sure to connect this wrist strap to the ground potential of the rack by means of a flexible lead integrating a 1 M resistor.g Note that the conducting parts of the split pin or the clamp should not be touched

when inserting/connecting (so as to avoid by passing the 1 M resistor).

2.1.2 System voltagesAll the system units require a power supply of -48 V DC (positive pole grounded). Only trained personnel should carry out those jobs.

Care must be taken because some parts heat up to a high operating temperature.

!DANGER:

This symbol is given to an item that explicitly endangers your life. Disobedience to this instruction can put you in imminent danger of death or serious injury.

!WARNING:

This symbol is given to an item that potentially endangers your life. Disobedience to this instruction can lead to death or serious injury.?

!CAUTION:

This symbol is given to an item that potentially endangers your body and property. Dis-obedience to this instruction can cause injury to you, or damage to the property such as equipments and the communication network.

Safety instructions

Protection against excessive voltage contact

2.1.3 Handling of componentsg Note when handling devices like PCs, monitors, printers, tape drives, etc. note the

manufacturers instructions.

Cards/modulesAvoid touching the component connections, connector contacts or conductor tracks (even when you are carefully grounded).

When extracting and inserting cards or modules, make sure you use the pulling and plugging handles provided!

Modules which are in a shielded unopened housing are protected in any event.

g Note that European standard EN61340-5-2/IEC61340-5-2 contains instructions on correct handling of electrostatic sensitive devices.

When you take a card/module out of its place in the system, lay it down on an antistatic mat.

Make sure that all measuring equipment used is grounded.

If you are using ungrounded measuring equipment, briefly connect the measuring probe to ground (discharge it) before performing measurements on cards or modules.

The plug connectors are unique coded to ensure that each card/module can only be fully inserted into a mounting location which cannot cause any damage to the component.

Cards/modules of the same type are fully interchangeable, provided that their hardware settings are corresponding (if applicable).

Moist cards/modulesAfter storage in a humid environment, modules with condensation moisture must be dried before they are used. This is important because otherwise the modules will be damaged or destroyed.

Special hint regarding the optical modulesCards/modules containing a laser device are marked with labels according to EN60825-1/IEC60825-1 and EN60825-2/IEC60825-2.

!DANGER:

In connection with all activities concerning power supplies, always consult the regulation VDE0105 / EN50110 (operation of heavy current systems) in regard to the safety pre-cautions to be taken.

!CAUTION:

If the cards/modules are only being gripped by their pulling and plugging handles, they should not be transported in a horizontal position (danger of breakage).

Figure 6 Laser warning labels

Fiber-optic cables must be handled appropriately and with due care. Cable must not be bent more tightly than the minimum bending radius (30 mm).

Optical connectors must not, in any circumstance, become kinked - even for a short period - or be subjected to impact loads. Similarly, tensile loading must not be imposed on these connectors.

Protective covers must be fitted to fiber-optic (FO) connectors that are exposed, i.e. not connected.

Mechanical damage of the FO surfaces inside optical connector surfaces reduces the transmission quality (increased attenuation).

2.1.4 Disposal of electrical and electronic equipment

LASER CLASS 1

!WARNING:

To avoid damage to health, you must observe the regulations regarding protection against radiation from laser devices (EN60825-1/2; IEC60825-1/2). You must always use dedicated laser-protective goggles. Never look into open fiber-optic cable ends, as this may damage your eyes.

So avoid any impact load when handling the connectors.

To create an optical connection with minimum attenuation it is important that the individual connector elements are properly and securely seated. The same applies to fiber-optic connectors on the optical cards.

Replacing BS-40 / 40 II units Fault clearance principle

Id:0900d8058048b21d

3 Fault clearance principleThis maintenance concept guarantees a simple and fast fault clearance and leads to high operationl efficiency.

3.1 Fault clearance principleThe high system functionality of the base station system is achieved by means of system-integrated routine tests. These routine tests continually check the correct func-tioning of the base station subsystems including the BTSEs. The fault clearance procedures in this manual are based on these routine tests. In most cases, the results of these routine tests are sufficient to localize the fault and clear it immediately at the BTSE.

The modular design of the BTSE allows you to clear a large percentage of faults in the system 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 to high operational efficiency.

3.2 Fault clearance guidelinesThe following diagram gives an overview of the fault clearance procedure (detailed description below):

Fault clearance guidelines(The numbering refers to the diagram displayed in Figure 7 Fault clearance overview.)

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 OMC must verify whether a local fault clear-

ance at the BTSE is required (see Radio Commander documentation).

g For the local fault clearance at the BTSE:Make sure that all spare parts that might be required to clear the fault are avail-able at the site. Note that sometimes more than one module may be suspected of being defective. This is particularly important if the failure is located in the TX/RX path (see fault clearance procedure "Cable Problems).

For general module replacement instructions also see section "Module replace-ment instructions".

4. Interpret the fault message and go to the fault clearance procedure of the suspected module or interface in Chapter 3 "Fault Clearance Procedures" (module/interface names as well as LMT terms (MOs) are listed in alphabetical 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 was successful: 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 cause of the fault, check whether there is another probable cause.

7. If there is another probable cause, reinsert the recently replaced original module and go to the corresponding fault clearance procedure for the next suspected module or interface.

8. It should be possible to clear most faults that may occur in the BTSE by following the fault clearance procedures described in this manual. However, if the fault should still exist after considering all probable causes, contact TAC. Here you will obtain help from specially trained troubleshooting experts.

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

3.4 Avoiding the loss of callsg The following procedure is only relevant if the BTSE is in phase 3. In phase 1 or 2,

the BTSE cannot establish calls.

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

6.3 AC/DC for BTSE type I

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

g This procedure describes the replacement of an AC/DC module for the BTSE type I (BS-240/BS-240XL/BS-241/BS-40/BS-41). For the BTSE type II see replacing unit AC/DC for BTSE Type II.

AC/DC or rectifier faults are also reported via the managed object ACDCP, which is related to the DCBCTRL. The fault message indicates the address of the corresponding DCBCTRL. Go to replacing unit DCBCTRL.

The AC/DC system is not configured as a managed object. To make AC/DC alarms visible, you must configure them as environmental alarms (ENVAs). For more informa-tion refer to the corresponding commissioning document.

If the AC/DC modules are not installed in redundant configuration, the system uses the backup battery for power supply and may switch to "Emergency Configuration if one or more power supply modules fail.

If one or more power supply modules fail in redundant configuration, there is enough power available from the remaining AC/DC modules, so that one AC/DC module can be replaced without any interruption of BTS operation.

!CAUTION Electrostatically Sensitive ComponentsModules are susceptible to damage by electrostatic discharge.

Follow ESD precautions when removing and inserting modules. See section ESD Pre-caution.

6.11 Cable problems

In most cases, alarms in the TX/RX path originate from loose or damaged cables. There-fore, the relevant cables should be checked first, according to the following procedure.

With the use of the FDUAMCO, additional error sources arise from the cabling.If the alarm cannot be cleared in this way, the suspected module must be replaced. Note that the failure cause may be located in the module(s) addressed in the error message as well as in any other module of the TX/RX path and the antenna subsystem. It is rec-ommended to start with the replacement of the module that is addressed in the fault message. Afterwards if the error is still there take the other modules in the TX/RX path into consideration.

Examples for alarms in the TX/RX pathRF power reflected into power stage

Cell 0,1,2: Antenna system TX

FICOM_VSWRP: VSWR alarm low or highDUAMCO (FDUAMCO, COAMCO): RX alarm low or highDIAMCO: RX alarm low or highTMA: RX alarm low or high

BS-240/240 II/240XL/240XL II/241/241 II:For the COAMCO, no specific alarm exists. Check the LEDs "POWER/ALARM" at the COAMCO. Red LEDs signal a defective COAMCO.


2 Remove the top cover (if necessary) Remove the top cover if the suspected module(s) are installed under the top cover.

3 Cable connections fastened correctly?Are the TX/RX cable connections of the suspected module(s) fastened correctly?

Yes h......... 8No h ......... 4

4 Fasten cable connectionsFasten the cables by tightening their coupling nuts with a torque wrench.
