質問 # 32
Which strategy most directly improves data center energy performance without compromising reliability when properly engineered and monitored?
正解：B
解説：
Huawei green data center concepts focus on reducing energy consumption through engineering controls rather than sacrificing resilience. Raising the allowable supply air temperature is a proven efficiency lever because it reduces compressor workload, expands economization opportunities where applicable, and can reduce fan energy when airflow is optimized. However, it must be implemented with airflow management-especially hot/cold aisle containment-to ensure server inlet temperatures remain within safe limits. Adaptive control is critical: monitoring rack inlet temperatures, cooling unit performance, and environmental conditions allows the system to dynamically adjust cooling output, fan speed, and setpoints to match real IT load. This avoids the common inefficiency of "overcooling for safety." When combined with standardized O&M procedures, alarm thresholds, and continuous trend analysis, the strategy improves overall energy performance while preserving reliability and service continuity. In contrast, permanent oversizing or forcing all redundant systems to run fully loaded wastes energy and can reduce operating efficiency. Properly engineered, monitored optimization delivers efficiency gains with controlled operational risk.
質問 # 33
Which of the following statements are true about the routine maintenance of a UPS?
正解：A、B、D
解説：
Routine UPS maintenance is preventive by design, so it must cover both environmental conditions and equipment operating status, not only alarms. The equipment room environment directly affects UPS reliability: high temperature accelerates capacitor aging, reduces battery/rectifier reliability, and may trigger derating; improper humidity increases the risk of condensation or electrostatic discharge; dust and poor housekeeping raise the risk of blocked airflow and overheating. Therefore, the environment check in option A is a standard routine item.
Option B is also essential because O&M personnel must confirm the UPS is in normal operating mode, verify no hidden alarms exist in the event log, and ensure the load level is within the recommended range to maintain redundancy and efficiency. Option C is true because fans are typical "wear-out" components; abnormal noise or speed changes often appear before a failure and can be detected early through inspection. Option D is false: absence of a front-panel alarm never replaces onsite environmental inspection and basic preventive checks.
質問 # 34
In a data center power distribution architecture, what is the primary function of a Static Transfer Switch (STS) for critical single-cord loads?
正解：C
解説：
Huawei data center power distribution design prioritizes continuity for critical loads. For single-cord IT equipment that cannot accept dual inputs, an STS provides a practical high-availability approach by connecting the load to two independent AC sources (often A and B feeds) and transferring the load to the healthier source when abnormalities occur. The key value is speed and coordination: the STS detects voltage/frequency deviations or source failure and performs a rapid transfer to minimize or eliminate interruption seen by the load. This supports O&M strategies where upstream systems (UPS, PDUs, distribution boards) are maintained or isolated without forcing downtime on single-cord devices.
In routine operations, STS status, transfer logs, alarms, and source quality parameters are monitored to prevent nuisance transfers and to ensure correct upstream selectivity and grounding. Correct commissioning also ensures the two sources meet synchronization conditions and that bypass
/maintenance procedures are standardized, improving safety and reducing operational risk.
質問 # 35
Which of the following interfaces is used to connect the controller and the main control module of the unit?
正解：A
解説：
In Huawei precision cooling units, the LCD controller (human-machine interface) must exchange real-time operating data and commands with the unit's main control module while also receiving a stable low-voltage power supply. This connection is typically implemented as alow-voltage communication bus plus DC power, which is why the interface is identified asI2C/12V. TheI2Cportion provides the data channel used for status display, parameter viewing/setting (within permission scope), alarm presentation, and command delivery (such as mute, reset, or control enable actions). The12 Vportion supplies power to the controller so it can operate independently of high-voltage power circuits and remain safe to access during routine O&M.
Interfaces likeDPandUSBare not used as the internal control link between the HMI and the main control board in this type of unit, and "SW" is not the designated controller-to-main-board interface in the standard wiring definition. Therefore,I2C/12Vis the correct selection.
質問 # 36
When tightening the screws (M16x50 mm) for the output power cables of lithium battery cabinets, what torque should be used to tighten and verify the screws?
正解：C
解説：
For Huawei SmartLi lithium battery cabinets, the output power cable termination uses high-current DC conductors, so the mechanical fastening torque is strictly specified to ensure both safety and long-term reliability. ForM16x50 mm screwsused on the+/N/# output cable terminals, the specified tightening
/verification torque is120 N m. This torque requirement is defined to achieve the correct clamping force between the DT terminal lug and the cabinet busbar/terminal surface. If the torque is below the requirement, contact resistance increases, which can lead to abnormal heating during charge/discharge, voltage drop, alarm events, and accelerated oxidation at the joint. If the torque is excessive, it can damage threads, deform the lug or busbar contact area, and introduce hidden mechanical stress that may loosen over thermal cycles. During commissioning and routine maintenance, technicians use a calibrated torque wrench to tighten and then re- verify each connection to the specified value to prevent hotspots and ensure stable operation under peak current conditions.
