Periodically check the system-connecting wires to make sure there are no weighty objects laying over them. distorted or tightened. thus preventing the wires from damages. Flood and Fire. Also. Faults statistics Make statistics of faulty modules in detail every week. detailed records are kept afterwards to serve as reference for avoiding similar troubles in days to come. Observation This is mainly to locate the trouble via viewing the alarm message from the OMCR management terminal. common measures are classified as follows: 1. poor contact found in modules and unit module.4 Common Maintenance Measures In daily maintenance.Maintenance Manual of ZXG10-BSC(V2) 2) Maintenance measures After viewing the alarm message from the OMCR system of BSS the subsystem. Observation is a first-of-all method that Page 5 of 106 . 2) Maintenance measures A Via plug/unplug. If problems remain unresolved even though simple measures listed above have already been taken. rapidly resolve the fault and notify it to the higher-level executives. you estimate the damages of hardware. 1. check the equipment room environment immediately. please contact technical personnel or local offices of ZTE immediately and notify it to related executives at the same time. locate the fault and confirm the reason. etc. Keep records in detail afterwards so as to help clear out similar hidden troubles in the days to come. Keep detailed records to help clear out the hidden troubles. Sudden failures of equipment itself 1) Primary faults Include hardware parts. Or by means of replacement or isolation. such as damages. partial problems such as designated position unavailable and poor contact can be solved. Also included are software parts like disordered data or programs. 2. Data disorder can be inquired and corrected via operation in the OMCR system of the BSS base station controller subsystem B Software/ hardware faulty phenomena are quite complicated. designated positions unavailable. when a module is powered on and self tested. refer to Appendix A for cautious items and operation procedures in the case of replacing boards and components. you isolate this part from related modules or racks to judge whether the fault results from interaction between then. The common isolation way is to self-loop the in/output interface of a certain module so as to isolate and remove the problems of the related system. 3. Therefore. Replacement Using a functionally proper module to replace the module to be checked to confirm whether the latter has gone wrong. Plug/unplug At the very beginning of finding faults in a certain module. Self-test When the system or module is powered on again. judge if there is any fault y way of self-test. This way will tell whether the module itself is faulty. 6. 5. In normal cases. Warning: When plugging/unplugging/replacing modules.Maintenance Manual of ZXG10-BSC(V2) the maintenance personnel use when encountering troubles. 2. maintenance personnel must be quite familiar with indicator lights on each module and be fully aware of the meanings of alarm information at different levels displayed on the management terminal. choose the replacement way. 4. The correct judging of the observed result is a key factor of correctly analyzing and resolving problems. If plug-unplug method doesn’t work. This will help remove the troubles resulting from improper contact. Press Turn off the power and then press the cable connectors. then plug/unplug the connector between the module and the external interface so as to remove the faults resulting from improper contact or processor abnormality. unclose the fastener on the front panel.

When replacing boards, the maintenance personnel are recommended to contact relevant technical professionals or the local office personnel of ZTE Corporation so as to get technical instructions. In the process of replacing boards, it is necessary to follow rules as follows: 1. In the usual time, the unopened spare parts should be kept in antistatic packages (Drier bags are preferred inside the bag) classified and saved in cartons. Types and models should be labeled clearly on the antistatic bags or cartons for the convenience of identification. 2. Wear antistatic wrist straps before plugging/unplugging boards. When holding boards in hand, be cautious enough to keep away from circuits, components, connection slots, etc. Never overexert yourself when you plug/unplug boards so as to prevent from distorting boards or the pins and slots on the backplane. 3. The removed faulty boards should be labeled with fault causes before put into the antistatic bags and should be kept in classification. 4. After the faulty boards are removed, if no spare parts are available at the moment, put an idle dam board onto the vacant position in order to keep clear of dust or play an ornate role. 5. Make sure to mount the module into its position. 6. Hot plug/unplug operation is strictly prohibited when replacing power boards or MP. A.2 1. Procedures of Replacing Public Boards Preparations before replacement Page 100 of 106 In the process of this operation. A sufficient provision of antistatic bags. program versions and words “fault”. First aim at the slot labeled on the insertion box in line with the spare board name. When using the standby board to replace the active board. thus enabling the new board to run in active status. perform the active/standby changeover first so as to enable the standby board to be in active status beforehand. Make sure that spare parts are functionally intact and their models comply with the faulty boards. Confirmation after replacement Page 101 of 106 2) 3) 2. drier bags and assorted cartons is available for convenience of labeling faulty components. you should try your best to avoid contacting the parts and circuits on the board Put the removed faulty boards into the antistatic bags with drier bags and label them clearly according to their models. attributed slots. 1) 2) 3) 4) 5) 6) 3. If the active board is to be replaced. you use the other hand to hold the lower edge of the board and then gently pull the board out from its slot. This shows the circuit board has reached its position.Maintenance Manual of ZXG10-BSC(V2) 1) By observing and analyzing errors. Replacement procedures Wear antistatic wrist straps. then use the thumb to press the fastener on the circuit board and push the circuit into the slot with average force until the fastener locks it up. locate the faulty boards and replace them. Put the faulty boards in the cartons in category and label them clearly on the cover of the cartons so as not to confuse them next time. . Using one hand to forcefully turn the fastener on the faulty board outwards and downwards. perform another active/standby changeover after the replacement is over. when the board is removed from the insertion slot and flip outwards. Remove the front door from t he rack and be careful to put it down lightly.Maintenance Manual of ZXG10-BSC(V2) When the circuit board is freshly inserted. if services operation recovers. Check and confirm whether the spare board is damaged or whether the fault is on other boards instead of on this one. it becomes a symbol of replacement success. including the 3×8 cable and the 6-chip POWP cables on both sides. 3) 4) 5) 6) Page 102 of 106 . Preparations before replacement Preparations to be made are the same as those before the replacement of public boards. 1) 2) Procedures of replacing shelves and backplanes Wear wrist straps and turn off power supply system. Remove the backplane of the this layer after unscrewing it. Loosen the 4 screws on the shelf of this layer by starting from the front of the shelf. Read A.2 for more details. the indicator lights will be in normal status. Pull out the shelf out from the front. The office party and the related technical personnel should acknowledge the replacement operation beforehand. A. 1.3 Replacement of Other Components In most cases. For more information on how to distinguish the display status of indicator lights. Write down the slots and positions where cables are located. Write down the specific boards and their corresponding slots and remove all the boards at this layer. If the self-test fails in that the self-test proceeds continuously or indicates abnormality and the related unit has not recovered its services. remove all the cables connected at the backplane. Locate the fault by observing the alarm of fore/background. 2. read Chapter 3 in this manual. If the self-test succeeds. this shows the replacement fails. there will be a self-test process lasting for some time. the components here refer to the whole layer shelf or the backplane. install the cable lock chip onto it in exactly the same manner as is with the old backpane. Put back the front door of the rack. MP initiation. the indicator lights will be in normal status. install the short circuit chip on the left and right sides of the new backplane. Only one of its directions (left and right) can be inserted. Make sure not to reverse the top/bottom directions of the backplane. If the 3×8 cable lock chip is unavailable on the 96-core socket of the new backplane. Based on the previous records. In the process of this operation. you should try your best to avoid contacting the parts and circuits on the board Be sure the cable connections and board slots are inerrable. Be careful with the two (left/right) directions of the 3×8 cable. you try the other direction. 8) 9) 10) 11) 12) 13) 14) 3 Power on the rack and initiate the system. Mount the shelf with new backplane onto the rack. Insert each board corresponding to the recorded slots. If services’ operation recovers. Merely the left or the right of the two directions can be locked if inserted by a lock chip. Exactly in the same manner as the removed backplane. board version loading and version running takes place respectively. so does the 6-core power supply cable. Warning: MP’ s power supply is –48V. If it fails. If the self-test succeeds. Other boards will be burnt if inserted to the MP slot.Maintenance Manual of ZXG10-BSC(V2) 7) Mount the new backplane onto the idle shelf (or install the backplane onto the new shelf). it symbolizes the replacement success. connect the power supply lines to the corresponding cables on the backplane. Confirmation after replacement There will be a self-test process lasting for some time before the system powers on after the replacement. For more information on how to distinguish the display status of indicator lights. read Chapter 3 in this manual. If the self-test fails in that the self-test proceeds continuously or Page 103 of 106 . Page 104 of 106 . this shows the replacement fails.Maintenance Manual of ZXG10-BSC(V2) indicates abnormality and the related unit has not recovered its services. Check and confirm whether the spare board is damaged or whether the fault is on other boards instead of on this one. Locate the fault by observing the alarm of the fore/background.
