問題 #24
In IT scenarios, which of the following are the power supply and distribution components of the FusionDC1000A?
答案:A,B,D
解題說明:
In the FusionDC1000A IT scenario, the power chain is built around an AC input, conditioned backup power, energy storage, and final distribution to the IT racks.Integrated UPSis the core power-conditioning component, providing voltage and frequency stabilization and uninterrupted supply during mains disturbances. The UPS works together withSmartLi, Huawei's lithium battery system, which serves as the energy storage unit to sustain the load during outages and to support controlled shutdown or generator switchover. After UPS output, power is delivered to the IT loads through thePower PDB, which performs downstream distribution, branch protection, and organized cable termination toward rack PDUs or IT equipment feeders. By contrast, anAC/DC power systemis typically associated with DC bus supply used in telecom-oriented or dedicated DC load scenarios, not the standard IT scenario architecture of FusionDC1000A that is centered on UPS plus battery plus AC distribution. Therefore, the correct components for IT scenarios are SmartLi, Power PDB, and Integrated UPS.
問題 #25
When the outdoor unit is installed at a position higher than the indoor unit, install an oil trap every five to six meters in the vertical direction along the gas pipe to ensure system reliability.
答案:A
解題說明:
This statement is true. In split DX/precision cooling refrigerant systems, the "gas pipe" typically refers to thesuction linereturning refrigerant vapor (and entrained compressor oil) from the indoor evaporator to the outdoor unit/compressor. When theoutdoor unit is higher than the indoor unit, the suction line includes avertical riser. Oil naturally tends to settle and flow downward under gravity, so without proper piping measures, oil may accumulate in low points or fail to be carried upward consistently, leading topoor oil return.
Insufficient oil return can cause compressor lubrication issues, abnormal noise, overheating, reduced efficiency, and long-term reliability risks. Installingoil trapsat the bottom of the riser and thenevery 5-6 metersof vertical lift helps collect oil and allows it to be periodically swept upward by refrigerant velocity, maintaining stable oil circulation. This requirement is especially important in data center cooling because continuous operation and high availability demand reliable compressor lubrication and stable refrigerant flow under varying load conditions.
問題 #26
In a data center power distribution architecture, what is the primary function of a Static Transfer Switch (STS) for critical single-cord loads?
答案:A
解題說明:
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.
問題 #27
What is the main function of an ATS (Automatic Transfer Switch) in a data center power architecture?
答案:A
解題說明:
An ATS automatically transfers the electrical load from a primary source (e.g., utility) to a secondary source (e.g., generator or backup feed) upon detecting a failure, helping maintain continuous power to critical loads.
問題 #28
What are the colors of indicators on the LCD panel of the MDU?
答案:B,C,D
解題說明:
On Huawei UPS systems (such as the UPS5000 series), the MDU LCD panel includes status indicators designed to provide an immediate visual understanding of the UPS operating condition and alarm severity. The indicator system uses three standard colors: green, yellow, and red.
Green indicates the UPS is operating normally and the power supply path is healthy. Yellow is used to show abnormal conditions that require attention, such as warnings or non-critical alarms, where the UPS can typically continue supplying power but O&M personnel should inspect and handle the issue within the required timeframe. Red indicates serious or critical conditions, such as major faults or alarms that may threaten continuous power supply or require urgent action according to operating procedures. These three colors align with the common Huawei alarm severity presentation logic on the UPS display and help technicians quickly judge whether the situation is normal, warning-level, or critical-level without entering deeper menus. Orange is not used as an MDU indicator color in this context.
