On the ECC800-Pro WebUI, the PUE configuration mode can be "Standard" or "User-defined".
Answer(s): A
Huawei’s ECC800-Pro supports PUE (Power Usage Effectiveness) management as part of its energy efficiency and green data center features. In practical O&M, different sites calculate PUE differently depending on metering topology, what loads are included (IT load only vs. auxiliary loads), and whether the site uses integrated modules (UPS, cooling, lighting, etc.) or external systems. To handle these real-world differences, the ECC800-Pro provides two PUE configuration approaches on the WebUI. “Standard” mode is used when the site’s metering points and calculation logic align with a predefined Huawei template, enabling rapid commissioning and consistent reporting. “User-defined” mode is used when the customer’s metering structure or management requirements differ—allowing engineers to select specific measurement points, define inclusion/exclusion rules, and tailor the calculation path so that displayed PUE matches the site’s accepted KPI definition. This dual-mode design ensures PUE is both standardized where possible and flexible where necessary, improving energy analysis accuracy and supporting optimization actions.
The NetEco service program backend can be accessed through the iBMC port.
Answer(s): B
In Huawei data center facility management, NetEco is the management software platform (server/application) used to centrally monitor and manage sites, while iBMC is the out-of-band hardware management interface used for server remote maintenance (such as power control, hardware health, BIOS settings, and remote console) on the specific server where iBMC exists. The iBMC port is not a service access interface for NetEco. NetEco’s backend services are accessed through the server operating system network interfaces (management/service network) and corresponding application ports after the server is properly networked and configured. Even if NetEco is deployed on a Huawei server that has iBMC, iBMC only provides a channel to manage the server hardware and does not expose NetEco application access as an official commissioning/O&M path. Therefore, NetEco backend access should be planned via the site’s management network (IP addressing, routing, security policy), not via iBMC.
The NetEco northbound interface does not support the SNMP protocol. Only WebService interfaces are supported.
In Huawei’s data center facility management architecture, the northbound interface of NetEco is designed specifically to integrate with upper-layer systems such as enterprise NMS platforms, SOC/monitoring centers, and customer unified O&M systems. To meet common industry integration practices, NetEco northbound capabilities are not limited to only one interface type. In addition to WebService-style interfaces used for richer data exchange and structured integration, NetEco also supports SNMP-based northbound integration, which is widely used for alarm forwarding, basic status monitoring, and interoperability with standard network management tools. SNMP is particularly common in mixed-vendor environments because it enables a lightweight and standardized method to deliver key alarms and events to a customer’s central monitoring platform without requiring deep application coupling. Therefore, the statement that “only WebService interfaces are supported and SNMP is not supported” is incorrect: NetEco northbound integration supports SNMP along with other northbound interface methods depending on the integration scenario and customer requirements.
Through device management, you can view the information about
Answer(s): A,B,C,D
In Huawei smart module management (such as on the ECC800-Pro/WebUI), Device Management is used to centrally view and maintain managed objects (UPS, SmartLi, rPDU, sensors, air conditioners, etc.). The Overview page provides a consolidated snapshot of a device’s operating status, key parameters, running mode, and basic identification information so engineers can quickly judge whether the device is healthy and online. The Alarm view lists active and historical alarms related to the device, supporting rapid fault isolation and verification after recovery. The Signal view shows monitoring points and I/O status (including analog values and digital inputs/outputs where applicable), which helps engineers confirm sensor wiring, linkage logic, and real-time state changes during commissioning and troubleshooting. The Service period information is used for lifecycle and maintenance planning, such as tracking service time, maintenance intervals, or component life indicators where supported, enabling preventive maintenance and reducing unexpected downtime. Therefore, Device Management supports viewing all four categories.
Which of the following are the user roles of Power Partner?
Answer(s): A,B,C,D,E,F
Power Partner is Huawei Digital Power’s partner service platform used to support delivery, commissioning, maintenance, and service operations across the full lifecycle of a project. To match real project workflows, the platform defines multiple user roles that align with different responsibilities and permission scopes. A Startup engineer focuses on commissioning activities such as obtaining startup authorization, performing initial configuration, and completing functional verification. A Service engineer handles routine maintenance, inspections, troubleshooting, part replacement guidance, and closure of service cases. A Project manager coordinates delivery milestones, resource planning, and overall service execution to ensure acceptance criteria are met. An Inventory operations manager manages materials/parts flow, tracking, and availability to support timely repair and maintenance. The DOC (Delivery/Dispatch Operations Center) role supports centralized operations such as work order dispatching, progress supervision, and process compliance. A service manager of a representative office typically oversees regional service quality, governance, and authorization control, ensuring the right people have the right access and that services are delivered according to Huawei process requirements.
The NetEco can be deployed on any virtualization platform.
NetEco is an enterprise management application with specific runtime dependencies, including supported operating system versions, database/middleware compatibility, CPU/memory/storage requirements, and network/security prerequisites. Because of these dependencies, Huawei does not treat NetEco as “hypervisor-agnostic for any virtualization platform.” In practice, NetEco deployment in virtualized environments is supported only when the virtualization stack meets Huawei’s compatibility requirements, such as validated hypervisors/virtualization solutions, proper virtual hardware settings, and resource reservation rules to ensure stable performance (especially for alarm processing, historical data storage, and northbound integration tasks). If deployed on an unverified virtualization platform, issues may occur such as clock drift, I/O latency, database performance bottlenecks, unstable NIC behavior, or unsupported VM device models, which can impact data collection, event correlation, and overall system stability. Therefore, the correct interpretation is that NetEco can be deployed on supported/verified virtualization platforms, not on any virtualization platform.
The software installation package does not need to be downloaded for the preinstalled server.
In Huawei delivery scenarios, a preinstalled server means the target software (for example, the NetEco platform and its required runtime components) has already been deployed and integrated on the server image before it is handed over for on-site commissioning. Because the installation media has already been applied, the on-site engineer’s work typically shifts from “software installation” to “environment verification and initialization,” such as confirming OS/service status, checking resource allocation, validating database and middleware health, verifying network planning (IP, gateway, DNS/NTP as required), and completing application-level initialization (site creation, user/role configuration, northbound interface settings, and device/model import if needed). In this case, downloading the full installation package is not a mandatory step for commissioning, because the package is mainly required when performing a fresh installation or reinstall/upgrade. However, standard practice is still to prepare supporting materials (patches, licenses, and compatibility documents) and ensure the preinstalled version matches the project baseline before acceptance.
The default port number for logging in to the NetEco is
Answer(s): C
In Huawei NetEco access design, the Web client is reached using HTTPS to protect credentials and management data in transit. During initial deployment and commissioning, engineers access the NetEco login page by entering the server IP address followed by the default HTTPS service port. Huawei’s standard login method specifies that users open a browser and enter https://NetEco server IP:31943 to access the NetEco login interface. This port is therefore treated as the default Web login port in typical on-premises NetEco deployments, and it is the baseline value referenced in installation and login guidance. Other ports may appear in specific tools, customized scenarios, version variants, reverse-proxy deployments, or when security policy requires port changes, but those are exceptions driven by planning or product packaging. For exam and commissioning purposes, the correct default login port is the one used by the NetEco Web client entry point under the standard deployment model: 31943.
