Maintenance Categories.............................................................................................1-1Precautions ................................................................................................................1-1

1.1 Maintenance CategoriesMaintenance can be classified into three categories: routine maintenance, notificationhandling, and alarm handling.

Routine MaintenanceRoutine maintenance means periodical maintenance. It involves checking the operationof equipment periodically. Any problems detected during the inspection should be handledimmediately to prevent accidents.

Alarm/Notification HandlingNotification handling involves analyzing the notifications generated during systemoperation, determining whether faults exist, and taking proper measures as required.Alarm handling involves analyzing the alarms generated during equipment operation,determining whether faults exist, and taking proper measures as required. For adescription of notification and alarm handling, refer to the ZXSDR B8200 L200(HV3.10)LTE Baseband Unit Alarm and Notification Reference.

1.2 PrecautionsDuring routine maintenance, follow the precautions below:

l Keep the equipment room dry, clean, and at normal temperature. Keep rats or otheranimals out of the equipment room.

l Ensure that the primary power supply of the system is stable and reliable. Checkthe system grounding and the lightning protection grounding regularly. Ensure thatthe lightning protection system is in good condition especially before a thunderstormseason or after a thunderstorm.

l Formulate complete rules for routine maintenance. Keep a detailed duty log ofthe operations, versions, data changes, upgrade, and faults of the system for faultanalysis and handling. Ensure a shift change record is available denoting clearresponsibility.

1-1


ZXSDR B8200 L200 Routine Maintenance Guide

l Never play games or surf the Internet on the PC. Never install, run, or copy anysoftware not related to the system on the PC. Never use the PC for other purposesnot related to work.

l Set the NetNumen passwords based on user levels and keep them open only tomaintenance personnel. Manage the passwords strictly and change them regularly.

l Receive induction training to learn about the equipment and network. Performmaintenance operations according to the instructions described in related manuals.Wear an antistatic wrist strap before touching the equipment to prevent accidentscaused by human errors.

l Do not reset the equipment, load or modify data without permission, especially theEMS database data. Data must be backed up before it is modified. A record ofthe modification should be made at the time. After data modification, the backupdata cannot be deleted until the system operates properly for a certain period of time(generally one week).

l Prepare the following common instruments and meters: flat head screwdriver, crossscrewdriver, signaling analyzer, network cable pliers, multimeter, AC power supply formaintenance, telephone line, and network cable. Test the meters regularly to ensureaccuracy.

l Inspect spare parts and accessories regularly to keep them in stock and in goodcondition. Protect them against moisture and mould. Separate the spare parts andaccessories from the replaced parts and accessories and label them respectively.Replenish the common spare parts and accessories as they are used up.

l Keep any software and documentation that may be used during maintenance in aspecified handy place for use when required.

l Lighting in the equipment room should meet maintenance requirements. Repair anybroken lights in time.

l Solve any detected problems in time. For any problems that cannot be handled,contact the local ZTE office.

l Place the contact information of the local ZTE office in a handy place and make itknown to all maintenance personnel. Update the contact information regularly.

Danger!

Power supply inspection and adjustment must be performed by professionals. Otherwise,injury, death, and equipment failures may occur.

Warning!

Data cannot be modified or synchronized without permission of the person in charge.Otherwise, major accidents may occur.
