NEW QUESTION # 62
When the mains supply is stable, the UPS5000-H mainly works in which mode after ECO is configured?
Answer: A
Explanation:
After ECO mode is enabled on the UPS5000-H, the system's control objective changes from "always supply the load through the inverter" to "maximize efficiency while keeping protection mechanisms ready." When themains input is within the configured ECO acceptance window(voltage, frequency, THD, and other quality thresholds), the UPS supplies the critical load primarily through thestatic bypass path, which has lower conversion losses than continuous double-conversion. The inverter remains synchronized and on standby, so if the mains quality deteriorates or an abnormal condition is detected, the UPS canrapidly transferthe load back to inverter operation to maintain output stability. Battery mode is only used when the rectifier/bypass source is unavailable or out of range, and maintenance bypass is a manual service path used for isolation during maintenance, not for normal energy-saving operation. Therefore, with stable utility power and ECO configured, the UPS5000-H mainly operates instatic bypass mode.
NEW QUESTION # 63
Video management can connect to the third-party video surveillance subsystem and play historical videos.
Answer: A
Explanation:
In Huawei's data center O&M architecture, video is treated as an important auxiliary capability for security and remote operation. The Video Management function is designed not only to view live camera feeds, but also to integrate video resources into the same O&M workflow as alarms, access control events, and environmental monitoring. In typical deployments, the actual video storage and recording are handled by a third-party video surveillance subsystem (for example, an NVR/VMS platform). Huawei's video management function can connect to that third-party subsystem so that camera resources can be accessed in a unified interface, allowing operators to perform linkage operations such as "view video on alarm" and routine security inspection without switching platforms. Because historical recordings are stored by the surveillance subsystem, once the integration is established and permissions are correctly configured, operators can retrieve and play back historical video for event tracing, audit, and incident investigation. This supports closed-loop O&M: alarm/event occurs -> video verification -> root-cause confirmation -> maintenance action -> evidence retention.
NEW QUESTION # 64
After the battery module is installed, the torque and insulation should be checked according to the specified requirements.
Answer: A
Explanation:
This statement is true because post-installation verification is a mandatory acceptance step for battery systems in data centers. After a battery module is installed, torque verification ensures that all power terminals, interconnect bars, and grounding points meet the specified tightening requirements. If torque is too low, contact resistance increases, which can cause abnormal heating, voltage drop, nuisance alarms, and even connector damage during high current charge/discharge. If torque is too high, threads, lugs, or busbars can be damaged, creating hidden reliability risks. Insulation testing confirms that the battery circuit has no unintended leakage paths to chassis or ground and that cable routing, connector seating, and protective covers are correct. This is especially important for lithium battery cabinets where high DC voltage and large fault current capability demand strict electrical isolation. Performing torque and insulation checks after installation reduces early-life faults, improves safety, and ensures the cabinet can pass commissioning tests and enter stable service under UPS charge/discharge control.
NEW QUESTION # 65
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.
Answer: B
Explanation:
For FusionCol8000-C chilled-water systems, Huawei commissioning requires awater leakage/pressure- holding teston the chilled-water piping after installation to verify joint sealing, valve interfaces, and connection integrity before long-term operation. The specified method is toraise the water pressure in the chilled-water pipe to 0.8 MPa, then observe for30 minutesto confirm there is no visible leakage. If the system remains dry, the same pressure isretained for 24 hoursas a stability verification step. The acceptance criterion is that thepressure drop is less than 0.01 MPaover 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.
NEW QUESTION # 66
The default address of the WAN1 port on the ECC800-Pro is
Answer: B
Explanation:
In Huawei smart module commissioning, the ECC800-Pro controller provides a dedicated management access path through its WAN ports. For on-site startup commissioning, technicians typically connect a laptop directly toWAN1and place the laptop IP address in the same subnet as the controller so they can open the WebUI and complete initial settings (time, network, device discovery, alarm checks, linkage tests, and parameter commissioning). Thefactory default IP address for WAN1 is 192.168.8.10, which is used as the initial access point before the address is planned and changed to match the customer's management network. This default design supports quick "point-to-point" commissioning without depending on upstream switches, DHCP services, or enterprise IP planning at the very beginning of deployment. After login, Huawei commissioning practice is to harden access (password/authentication completion), then update network parameters and integrate the ECC800-Pro into the site monitoring network to enable continuous O&M, remote alarm reporting, and device management.
