1.8 ReliabilityThis chapter describes the reliability of the BTS3911E, including system reliability, hardwarereliability and software reliability.System ReliabilityThe BTS3911Es adopt redundancy design and improved fault detection and isolation solutionsto enhance system reliability.lRedundancyKey files, such as software versions and data configuration files, all support redundancy.lReliabilityA BTS3911E automatically detects and diagnoses faults in the software, hardware, andenvironment, and reports alarms. Then, the BTS3911E takes self-healing measures to clearthe faults. If the faults cannot be cleared, the BTS3911E isolates the faulty units.Hardware ReliabilitylOvertemperature protectionIf the temperature around a power amplifier (PA) in a BTS3911E is too high, the BTS3911Ereports an overtemperature alarm and handles the problem as follows:lIf the temperature is higher than the threshold for a major alarm, the BTS3911E switchesoff the PA and stops providing services. This protects the BTS3911E from damage causedby increasing temperature.lIf the temperature is higher than the threshold for a minor alarm, the BTS3911E enablesthe temperature derating function to ensure the services of admitted UEs and refuses theaccess requests of new UEs to prevent the temperature from keeping increasing.This function protects the PA from damage caused by overtemperature.lReliable power supplyThe BTS3911Es use the following techniques to achieve a reliable power supply:lSupport for a wide-range of voltages as well as surge protectionlPower failure protection for programs and datalPower supply protection against overvoltage, overcurrent, and reverse polarity protectionand negative poleslSurge protectionThe BTS3911Es take surge protection measures on AC power sockets, FE/GE ports,antenna connectors, and clock ports.Software ReliabilitylRedundancyTo ensure normal operation of a BTS3911E when errors occur in important files or data,the BTS3911E provides the following redundancy functions:BTS3911ETechnical Description 1 BTS3911E Technical DescriptionIssue Draft A (2015-07-30) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.27
lSoftware version redundancy: The BTS3911E stores software versions, including theBootROM version, in different partitions to provide redundancy. If the active version isabnormal, the BTS3911e switches to the backup version.lData configuration file redundancy: The BTS3911E stores data configuration files indifferent partitions to provide redundancy. If the current file is damaged, the BTS3911Ecan continue working properly by loading the backup file.lError tolerance capabilityIf software errors occur, the self-healing capability prevents the BTS3911Es from collapse.The software error tolerance capability covers the following aspects:lScheduled checks of key resources: A BTS3911E checks software resource usage andgenerates related logs and alarms. This allows the BTS3911E to release unavailableresources.lTask monitoring: When software is running, a BTS3911E monitors the running status ofevery task for errors and faults. If an error or fault is detected, an alarm is reported and self-healing measures are taken to restore the task.lData check: A BTS3911E performs scheduled or event-triggered data consistency checksand restores data consistency selectively or preferentially. In addition, the BTS3911Egenerates related logs and alarms.lWatchdog: In the event of a software error, a BTS3911E detects the error using the softwareand hardware watchdogs and automatically restarts.BTS3911ETechnical Description 1 BTS3911E Technical DescriptionIssue Draft A (2015-07-30) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.28
