질문 # 19
The FusionCol8000-A230 unit uses two systems. Each system uses three compressors connected in parallel and two EEVs.
정답：B
설명：
For FusionCol8000-A230, the "two systems" part is correct: Huawei's quick guide explicitly states that the indoor and outdoor units consist of two independent cooling systems, which is the basis for redundancy and staged capacity control. However, the rest of the statement ("each system uses three compressors connected in parallel and two EEVs") is not supported as a fixed, universal configuration in the installation/commissioning guide text that is available here. In Huawei smart cooling designs, compressor quantity and the number of electronic expansion valves (EEVs) are model- and configuration-dependent and are tied to how the refrigerant circuit is partitioned (for example, multiple compressor stages for capacity modulation, and one or more EEVs for different evaporator branches). Because the documentation we can directly verify confirms two independent systems but does not confirm "three compressors per system" as an explicit requirement, the combined statement (two systems + specific compressor/EEV counts) is judged false: one part is verified true, while the detailed component count cannot be confirmed as stated.
질문 # 20
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?
정답：C
설명：
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.
질문 # 21
Which of the following is the procedure for replacing a damaged UPS power module onsite?
정답：B
설명：
For onsite replacement of a UPS power module, Huawei's maintenance logic follows a safe
"isolate remove insert re-enable" sequence controlled by the module ready switch. During removal, the ready switch must be rotated to the OFF state first so the module is logically isolated from operation and will not participate in power conversion. After isolation, the four fixing screws are removed and a short waiting period is required to allow internal energy in capacitors to discharge before the module is pulled out. This matches statement . During installation, the ready switch must remain OFF before insertion to prevent unintended startup or arcing during connector engagement. The module is placed in position, inserted slowly and evenly until fully seated, then secured with the four screws. Only after mechanical fastening and full seating is confirmed should the ready switch be rotated to the ON state to allow the system to recognize and bring the module online. This matches statement .
질문 # 22
Which of the following statements are true about the routine maintenance of a UPS?
정답：B,C,D
설명：
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.
질문 # 23
Which O&M practice is most effective for identifying cooling inefficiency caused by airflow problems in an operating data center?
정답：B
설명：
Huawei facility O&M methods emphasize using monitored operating data to locate inefficiencies before they become faults. Airflow-related cooling inefficiency commonly appears as hot spots at rack inlets, elevated return air temperature fluctuations, abnormal fan speed increases, or uneven temperature distribution across aisles. By trending rack inlet temperature sensors alongside cooling unit supply
/return temperatures and fan speed or airflow commands, operations teams can distinguish between insufficient cooling capacity and poor airflow organization. Recirculation (hot air returning to rack inlets) often raises localized inlet temperatures without a proportional rise in room average temperature, while bypass (cold air short-circuiting back to returns) reduces cooling effectiveness and can drive fans to higher speeds unnecessarily. Data-driven checks support targeted corrective actions such as sealing cable openings, adjusting floor tile placement, restoring containment integrity, balancing airflow, or optimizing setpoints. This approach improves thermal stability, prevents overcooling, reduces energy waste, and aligns with Huawei's emphasis on integrated monitoring and closed-loop optimization for reliable, efficient operation.
