質問 # 62
When a critical alarm is generated for the unit, the indicator on the LCD controller turns red and the buzzer beeps continuously.
正解:A
解説:
In Huawei data center facility equipment (such as precision cooling units and related controllers), alarm presentation follows a clear severity-based design so technicians can recognize urgency immediately without entering detailed menus. Acritical alarmrepresents the highest severity level and is treated as a condition that may impact safe operation, cooling continuity, or equipment protection. For this reason, the LCD controller uses the most prominent visual and audible indications: theindicator turns redto show critical severity, and thebuzzer sounds continuouslyto ensure the alarm cannot be overlooked in a noisy equipment-room environment. This behavior supports rapid response: O&M personnel can quickly identify that immediate action is required, then open the alarm list to locate the root cause, confirm whether the unit has derated or stopped, and execute the prescribed troubleshooting steps (for example, checking power status, sensor readings, fan/compressor status, water flow/pressure, and protection interlocks). Therefore, the statement correctly describes the standard critical-alarm indication method on the LCD controller.

Which of the following is the cabling mode of external power cables in IT scenarios of the FusionDC1000A?
正解:B
解説:
In the FusionDC1000A IT scenario, the external input power cables are designed to enter the power distribution system through dedicated cable inlets at the bottom of the Power PDB. During installation, the procedure requires opening the Power PDB, removing the plugs from the bottom 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 is bottom cabling.

After installing the FusionCol8000-C (110-440 kW), inject water to preserve the pressure for the chilled water pipes to how many MPa. After 30 minutes, check that no leakage occurs. Preserve the pressure for 24 hours. If the pressure drop is less than 0.01 MPa and no leakage occurs, the pipes do not leak.
正解:D
解説:
For FusionCol8000-C chilled-water systems, Huawei commissioning requires a water leakage/pressure-holding test on the chilled-water piping after installation to verify joint sealing, valve interfaces, and connection integrity before long-term operation. The specified method is to raise the water pressure in the chilled-water pipe to 0.8 MPa, then observe for 30 minutes to confirm there is no visible leakage. If the system remains dry, the same pressure is retained for
24 hours as a stability verification step. The acceptance criterion is that the pressure drop is less than 0.01 MPa over the 24-hour period and no leakage is found, which demonstrates that the piping and fittings meet tightness requirements under the prescribed test pressure. This procedure helps prevent future failures such as slow seepage, corrosion around joints, insulation waterlogging, and unexpected shutdowns caused by water loss or low differential pressure alarms. It also ensures that subsequent flushing, venting, and operational commissioning can be performed safely and reliably.
質問 # 65
Which of the following are the functions of the SmartLi 3.0 battery control unit (BCU)?
正解:A、B、C、D、E、F
解説:
In Huawei SmartLi 3.0, the BCU acts as the cabinet-level "brain" of the lithium battery system, coordinating measurement, control, protection, and communication. It manages and supervises BMUs inside the cabinet by collecting key operating data such as voltage, temperature, SOC, and SOH, and by aggregating module information for higher-level management. The BCU supports charge/discharge management by monitoring string current and controlling operating behaviors to keep the battery within safe electrical and thermal limits. To ensure consistent performance across parallel strings and cabinets, it implements intelligent voltage sharing and active current balancing, which helps equalize currents, improve utilization, and reduce uneven aging. For safety and reliability, the BCU provides fault diagnosis and protection, including handling events such as overvoltage, undervoltage, overcurrent, and overtemperature, and it can isolate abnormal loops when required. SmartLi 3.0 also incorporates internal short-circuit risk prediction as part of its safety strategy. Finally, group capacity testing is supported as a maintenance function to verify usable capacity and system health.

What is the primary function of the ECC800-Pro in a Huawei smart data center facility solution?
正解:D
解説:
The ECC800-Pro is Huawei's smart module controller, providing unified monitoring, alarm management, device commissioning (via WebUI/app), and coordination of subsystems such as power, cooling, environment sensors, and access control within the cabinet or module.
