After replacing the fan, choose "Menu > _____ > Performance Maintenance" on the main screen to enter the
"Performance Maintenance" screen and clear the accumulated runtime of the indoor fan.
正解：C
解説：
In Huawei room air conditioner and precision cooling unit O&M, fan replacement is treated as a maintenance activity that must be recorded in the controller so lifecycle management remains accurate. The controller tracksaccumulated runtimefor wear components such as indoor fans to support preventive maintenance planning, alarm thresholds, and performance analysis. After a fan is replaced, the old runtime value must be cleared so the system can correctly measure the new fan's service hours, avoiding premature "maintenance due" prompts or misleading reliability assessments. This function belongs to themaintenancefunction set rather than alarm viewing, parameter settings, or basic running status. Therefore, the correct navigation is throughMenu > Maint > Performance Maintenance, where the technician can locate the indoor fan runtime item and reset/clear it after confirming the replacement. Performing this step ensures consistent O&M records, supports correct maintenance intervals, and helps troubleshooting by aligning future fan-related alarms with the actual operating hours of the newly installed component.

Which of the following is the cabling mode of external power cables in IT scenarios of the FusionDC1000A?
正解：D
解説：
In the FusionDC1000A IT scenario, the external input power cables are designed to enter the power distribution system throughdedicated cable inlets at the bottomof the Power PDB. During installation, the procedure requires opening the Power PDB, removing the plugs from thebottom cable holes, and routing the external input power cables into the cabinet through these bottom entries before arranging them along the nearby cable support/bridge inside the Power PDB area. After the cables are terminated (for example, L1/L2
/L3/N and PE), the bottom cable entries are resealed using waterproof sealing materials to maintain enclosure protection performance. This bottom-entry method supports reliable mechanical routing for thick/armored power cables, reduces bending stress, helps maintain orderly segregation from signal cabling, and improves on-site safety by guiding high-current cables through a controlled inlet path. Therefore, the correct cabling mode for external power cables in FusionDC1000A IT scenarios isbottom cabling.
質問 # 79
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 bothenvironmental conditionsandequipment 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, theenvironment checkin option A is a standard routine item. Option B is also essential because O&M personnel must confirm the UPS is innormal 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 # 80
Which of the following is not a scenario-based solution for Huawei data center products?
正解：B
解説：
Huawei's scenario-based data center facility portfolio is organized around clearly defined solution families that map to typical deployment scenarios and site sizes. FusionModule500 and FusionModule2000 are smart modular data center solutions designed for standardized, fast deployment in equipment rooms and enterprise edge/branch scenarios.They integrate key subsystems such as power supply and distribution, cooling, monitoring, and optional fire protection into a modular architecture that reduces footprint and accelerates on- site delivery. Likewise, FusionDC1000 is Huawei's prefabricated modular data center series, delivered as complete, factory-integrated modules that combine civil engineering elements with electromechanical infrastructure for rapid construction, predictable quality, and scalable expansion across different capacity tiers. In contrast, FusionDC800 is not used as a defined scenario-based solution name within Huawei's mainstream data center facility solution lineup (where "FusionDC" offerings are represented by the FusionDC1000 series and "FusionModule" offerings by numbered FusionModule solutions). Therefore, FusionDC800 is the option that does not match Huawei's scenario-based solution naming.
質問 # 81
During wizard startup, when you enter the screen for selecting commissioning items for the first time, all items are selected by default. Which item is mandatory. You can deselect other commissioning items that are not mandatory.
正解：B
解説：
In Huawei precision cooling commissioning, the wizard groups functional commissioning items so technicians can validate key subsystems efficiently. Thecooling system commissioningis mandatory because it verifies the primary control and protection loop that directly determines whether the unit can safely provide cooling capacity. This includes confirming the refrigeration or chilled-water cooling path can start and stop correctly, sensors and control logic are valid, and protection conditions (such as abnormal pressures
/temperatures, flow conditions, or interlocks) behave as expected. Without completing cooling-system commissioning, the unit's core purpose-stable temperature control for IT loads-cannot be assured, and the controller cannot reliably judge normal versus fault states during operation.
Other items (indoor fans, condensate pump, humidifier) are important butscenario-dependent: some sites do not use humidification, some drainage designs do not require an internal condensate pump, and fan checks can be handled as part of broader functional tests or may vary by redundancy configuration. Therefore, the wizard allows non-mandatory items to be deselected, but the cooling system commissioning must remain selected to complete a valid baseline commissioning workflow.
