1 Safety Rules and Precautions

1 Safety Rules and Precautions This chapter contains the following safety rules and precautions: Safety rules for equipment under power Electrostatic precautions.

Injury from Equipment Possible death or serious physical harm to personnel and damage to equipment may result from mishandling. While performing any maintenance tasks or procedures, you must follow any local safety requirements, those mentioned in General Safety Instructions for Field Operations and this chapter.


13 / 182


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

1.2 Electrostatic Precautions 1.2.1 Environment The following electrostatic precautions must be observed: Ensure that work benches, stools, and floor mats have a conducting surface connected to ground. Before handling static-sensitive components and assemblies, ground yourself to the conducting surface using an anti-static wrist strap When handling static-sensitive components and assemblies, do not wear or use clothes made of wool, nylon or any other synthetic material. Such fabrics are major sources of static build up When handling static-sensitive components and assemblies, do not use gloves and finger covers, unless they are made of cotton.

1.2.2 Tools The following electrostatic precautions must be observed: Ensure that all the tools which come into contact with static-sensitive components are at the same voltage level as the conducting work surfaces and floor mats. These tools include soldering irons, oscilloscopes, power supplies, and metal 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 contacts on 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 dry cleaning methods.

14 / 182



1.2.3 Transportation and Storage The following electrostatic precautions must be observed: Pack all containers used to transport and store static-sensitive components, and use aluminium container tubes if possible. If not, insert the component terminations into electrically conductive foam Before shipping a PBA, wrap it in a conducting synthetic bag or in aluminium foil. Also pack the PBA in a polyethylene transport box Before shipping a PBA which has MOS components, ensure that an appropriate warning symbol is displayed on the package Store spare PBAs in their appropriate polyethylene boxes. Keep the boxes closed 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 airborne particles that may cause damage Do not stack PBAs side-by-side or on top of each other with the board surfaces or components in contact with one another Before cleaning a PBA, remove or disconnect the damage protection, such as protective foam, to allow the PBA to be cleaned thoroughly. Replace the damage protection upon completion of the task.

1.2.4 Components and PBAs The following electrostatic precautions must be observed: Components and PBAs not in protective containers, must only be handled by trained personnel in static-controlled work areas Before removing a PBA from an equipment rack, discharge any static by touching 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 apply direct 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 soldered side down on a conductive surface Do not scratch or rub the soldered side of a PBA with a sharp or rough object 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.

Adjust Output Frequency

To adjust the output frequency of a CGU in a 9110 Micro BTS/9110-E Micro BTS: 1. Unlock the bottom section of the front protective cover on the BTS, and open it downwards to expose the COBO. Then, loosen the retaining bolts on the front cover of the COBO and remove it from the COBO base. 2. Connect the BTS NEM to the MMI port in the COBO. 3. Connect the frequency counter to the clock output connector on the COBO. 4. Wait until triggering occurs on the input signal port of the frequency counter, and the display provides at least nine digits of resolution. Then proceed as follows: If the indicated frequency is between 2 166 666.55 Hz and 2 166 666.77 Hz, proceed to Step 6 If not, adjustment is necessary. Continue with Step 5. 5. Use the BTS NEM (see BTS NEM User Guide ’Adjust the OCXO’) to adjust the BTS clock for a frequency between 2 166 666.55 Hz and 2 166 666.77 Hz. 6. Disconnect the frequency counter from the COBO. 7. Disconnect the MMI cable from the COBO and remove the terminal. 8. Replace the COBO front cover in position over the base and tighten the retaining bolts. Then, close the bottom section of the front protective cover on the BTS, and lock it.
