In IT scenarios, which of the following are the power supply and distribution components of the FusionDC1000A?
Answer(s): A,B,C
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 UPS is the core power-conditioning component, providing voltage and frequency stabilization and uninterrupted supply during mains disturbances. The UPS works together with SmartLi, 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 the Power PDB, which performs downstream distribution, branch protection, and organized cable termination toward rack PDUs or IT equipment feeders. By contrast, an AC/DC power system is 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.
The default address of the WAN1 port on the ECC800-Pro is
Answer(s): D
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 to WAN1 and 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). The factory 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.
In a data center fire protection design, which approach best matches Huawei facility practice for protecting IT rooms while minimizing secondary damage to IT equipment?
Answer(s): B
Huawei data center facility design typically follows a layered fire protection concept: early detection, controlled alarm linkage, and suppression methods that protect equipment and ensure personnel safety. A smoke detection system (often combined with staged alarms) provides early warning so operators can verify events and initiate emergency procedures. For the IT white space, a clean-agent gas extinguishing system is preferred because it suppresses fire without leaving residue and significantly reduces the risk of corrosion or contamination compared with powder-based agents. The extinguishing system is normally integrated with linkage/interlock controls: audible/visual pre-discharge alarms, time delay, emergency abort, door access control logic, and HVAC shutdown or damper control to help maintain agent concentration. This coordinated mechanism reduces false discharge risk while preserving a reliable automatic response if a real fire develops. In contrast, relying only on manual extinguishers is too slow for rapid fire growth, and water sprinklers alone can cause substantial collateral damage to servers and power equipment.
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.
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.
